543 F.2d 1333 | D.C. Cir. | 1976
Lead Opinion
Appellants have been found guilty by a jury on numerous charges emanating from two armed robberies in the District of Columbia and the slaying of a police officer as the aftermath of one. On the verdicts, the trial judge entered judgments convicting appellants and sentencing them to long terms of imprisonment.
I. THE FACTUAL BACKGROUND
We start with a summary of the events comprising the offenses with which appellants were charged and the major developments at the trial ensuing. Our recitation is not nearly exhaustive of the innumerable details,
A. The Offenses
The two holdups from which the charges in suit emanated took place on May 24 and 25, 1971. On the first date, at about 11:00 a. m., appellants entered a branch office of the American Savings and Loan Association at 4900 Massachusetts Avenue, N.W.
Both men fled from the building on foot. Officer Nelson Gosnell, already staking out a nearby bank, observed them as they crossed an adjacent parking lot to an intersection, at which point they separated and casually walked away in different directions. In a matter of minutes, Officer Gosnell responded to the report of the holdup of American Savings, but by that time appellants had escaped and no one was able to track their movements.
On the next morning, May 25, again about 11:00 a. m., the second holdup occurred at a branch of the National Permanent Federal Savings and Loan Association
While Ms. DuTeil was preoccupied with Timm, Caldwell appeared at her window, this time wearing a beard and collar-length hair. As she turned to assist Caldwell at the window, he produced a gun and directed her to put money into a briefcase. Although she readily complied, Caldwell demanded to know “where . . you keep the big money?” When she informed him that only the vault contained a larger amount, he ordered her to open it.
Her unsuccessful fumbling in the vault room was noticed by the manager, William Garnett, and as he came to investigate he too was ordered at gunpoint to open her teller’s vault. At last, he obtained approximately $5,000 in old bills and about $175 in bait money from each of two tellers’ drawers. Garnett and Ms. DuTeil were told to stay in the vault room for five minutes and not to set off the alarm, under Timm’s threat to shoot people on the street if his orders were not followed.
As soon as the two left the premises, Garnett informed Officers Sigmon and Schwartz, the policemen in the back, that a robbery had taken place. Officer Sigmon thereupon left by the front door, the same exit used by appellants. The felony-murder in this case was soon to follow from the attempted capture of appellants and a shootout which then ensued.
Appellants had walked through a nearby parking lot, but, they turned back and began to run when they heard Officer Sigmon’s demand for them to halt. Almost immediately the gunfire began, though it remains uncertain who fired first. Shooting as he ran ahead of Timm, Caldwell headed for a flight of stairs leading to an alley; following Caldwell’s progress, Officer Sigmon took cover, crouching down with his left side against a retaining wall. Other law enforcement officers in the vicin
Officer Sigmon was in a position which blocked Timm’s escape route. At a pace described as “walking” to “rather fast,” Timm approached Officer Sigmon from behind, the officer, facing Caldwell, being unaware of his presence. Timm then shot the officer in the back from a distance noted by witnesses as varying from six inches to four feet. From the wound thus inflicted Officer Sigmon died.
Officer Wade Bishop then opened fire on Timm, but soon was forced to retreat and call for assistance. Timm and Caldwell managed to reach their getaway vehicle, a blue panel truck driven by a young woman later identified as Heidi Ann Fletcher,
B. The Trial
After various pretrial proceedings consuming several months’ time, appellants reached trial. The trial, by a sequestered jury, lasted three weeks. During the first five days the Government presented its case, which involved 52 witnesses and about 120 exhibits.
The Government’s proof of the events comprising the offenses on trial was unopposed,
Although appellants entered the American Savings branch dressed in disguises, the attempt to mask their identities, as we have indicated, did not prove to be a problem for witnesses there. Ms. Wells, the branch manager, picked Caldwell as one of the robbers and testified that a brown wig found in the panel truck corresponded with the length and color of his hair. Ms. Younger stated that a black wig found in
There was also a great deal of other evidence directly implicating the two men, including items uncovered by a search of the panel truck
Insanity defenses presented by appellants were their only responses to the charges, and here also the judge and jury were presented with an extensive group of lay and expert witnesses. The gist of Timm’s defense was that he suffered from acute and long-standing dependency needs, and that this, coupled with Caldwell’s great influence over him, brought about his participation in the robberies. In contrast, Caldwell attempted to show that at the time of the offenses he was afflicted with a “conversion hysteria” — a deep-seated complex which allegedly had progressed since childhood and which ultimately led him to seek punishment from other people. The “conversion” aspect, as interpreted by his experts, took the form of lawbreaking in hope of being caught.
Such were the offenses and the trial, viewed in rather broad outline. There were, we have indicated, many other factual developments bearing on the legal issues posed on this appeal. We elaborate on these as separate discussions of the issues are successively reached in this opinion.
II. PRETRIAL PUBLICITY AND SELECTION OF THE JURY
A. Publicity and Claims of Prejudice
Appellants jointly contend that due to widespread publicity surrounding the case they were denied the “impartial jury” guaranteed to them by the Sixth Amendment.
Initially, appellants charge that a change of venue was necessitated by extensive media coverage that highlighted, among other things, Officer Sigmon’s death, appellants’ unorthodox life style and various controversies punctuating certain of the pretrial hearings. They specifically assert that the substance of news articles appearing in the press effectively prejudged their guilt. Furthermore, they add, the District Court’s acceptance of Heidi Fletcher’s plea of guilty prior to trial
Neither appellant has convinced us alternatively that the trial judge erred in failing to order sua sponte a severance of defendants
Additionally, we reject appellants’ claim that the trial judge erroneously omitted to take steps to restrict the spread of information about the case. They argue that the judge should have sealed more of the pleadings, held more proceedings in camera and restricted the prosecution’s press statements under rules in vogue in the District Court.
On none of these points do we find reversible error. Again, appellants did not avail themselves of their right to move
We discern no error by the trial judge in not instituting further restriction on disclosures to the press by government personnel. Appellants do complain of news accounts containing remarks attributed to governmental sources.
More importantly, there is a crucial weakness which plagues appellants’ claims of error as to the handling of pretrial publicity. Appellants’ only defense was insanity, not factual innocence. Thus the requirement of showing prejudice from the publicity complained of became in turn a requirement of demonstrating impairment of the ability or willingness of potential jurors to remain impartial on the insanity issue, and this appellants entirely failed to do. Throughout all of their descriptions and protestations of pretrial press coverage,
B. The Voir Dire Examination
The issues which appellants place before us concerning the selection of the trial jury necessarily flow into their basic contention that they were prejudiced by undue publicity. We are advertent to the principle that voir dire procedures must provide “a full and fair opportunity to expose bias or prejudice on the part of the veniremen,”
Appellants argue first that the trial judge erred in not probing more vigorously the responses of potential jurors as to their exposure to press coverage of the robberies and related offenses. Furthermore, they say, the judge erroneously relied upon the personal assurances of impartiality of certain of the veniremen after only cursory questioning.
Scrutinizing the record, we are satisfied that appellants have no basis for complaining of an inadequate voir dire examination. At no time did attorneys for either appellant tender an objection to the procedure, but we pause briefly to discuss their contentions and decline to find plain error. Their counsel were granted full opportunity to propound their own questions for each potential juror, and the substance of the questions suggested by defense counsel were put to the jury by the judge.
Moreover, in United States v. Robinson
appellate' review of voir dire issues. “Pursuant to Rule 24(a), Fed.R.Crim.P., the trial judge is vested with ‘broad discretion’ in the conduct of voir dire — both as to the mode and manner of proceeding,”
Caldwell and Timm also challenge the trial judge’s reliance on the personal claims of two potential jurors that they could render a fair and impartial verdict on the evidence to be adduced. Both of these individuals, they argue, should have been stricken for cause.
Instead of a perfunctory determination of their eligibility to serve, the judge asked followup questions
Lest we forget, the competence of a citizen to sit on trial juries is to be measured by a common-sense standard. For this and other cases in which similar claims are made, the Supreme Court has prescribed the applicable test:
It is not required . . . that the jurors be totally ignorant of the facts and issues involved. In these days of swift, widespread and diverse methods of communication, an important case can be expected to arouse the interest of the public in the vicinity, and scarcely any of those best qualified to serve as jurors will not have formed some impression or opinion as to the merits of the case. This is particularly true in criminal cases. To hold that the mere existence of any preconceived notion as to guilt or innocence of an accused, without more, is sufficient to rebut the presumption of a prospective juror’s impartiality would be to establish*1347 an impossible standard. It is sufficient if the juror can lay aside his impression or opinion and render a verdict based on the evidence presented in court.51
Our careful study of appellants’ objections in light of the record persuades us to the conclusion that here the test was satisfactorily met.
Appellants would also have us find reversible error in the trial judge’s failure to strike, sua sponte, for cause an entire class of prospective jurors — policemen’s relatives. They urge that the judge was under a duty to eliminate two potential jurors who at that time were closely related to District of Columbia police officers.
In several jurisdictions, the law is established that “[t]he mere fact of membership on a police force is not presumptively a disqualification for service on a jury in a criminal trial.”
On its own facts, we are inclined to distinguish this case from claims of prejudice arising from jurors who are former victims of the same type of crime being tried,
III. PRETRIAL COMPETENCY DETERMINATION OF CALDWELL
Caldwell urges reversal of his conviction on the ground of insufficient inquiry into his mental competence to continue to stand trial after an apparent attempt to commit suicide.
As in every case wherein the issue arises, we hold fast to the principle that “the conviction of an accused person while he is legally incompetent violates due process.”
Retracing his arguments, the only matter to be explored at the second hearing was whether Caldwell’s apparent
attempt to harm himself seriously rendered him incompetent
Much the same reasoning leads us to conclude that the trial judge’s handling of the original competency hearing was without error. In the course of taking both lay and expert testimony, the judge sought to ferret out those rudimentary patterns of voluntary behavior which would indicate whether Caldwell’s condition met the criteria for a finding of competence. Upon examination of the record, it is plain that the substance of lay testimony was supportive of Caldwell’s awareness of things around him and, as well, his ability to communicate with others. In sum, the evidence was merely contradicted, and the judge found the Government’s evidence more persuasive.
IV. RESTRICTIONS ON PRESENTATION OF EVIDENCE
Since appellants offered only the defense of insanity, their complaints concerning the conduct of the trial focus importantly upon the trial judge’s regulation of the content of expert testimony on that subject. Both appellants contend that their efforts to prove lack of criminal responsibility for their acts were frustrated by certain of the trial judge’s evidentiary rulings. Although
A. The Insanity Defense: Caldwell
The first instance of alleged prejudice to the presentation of Caldwell’s insanity defense began prior to commencement of the trial and culminated during cross-examination of his witnesses. The court enlisted the aid of various experts to make a pretrial determination of Caldwell’s competence to stand trial. The gist of the problem is that the judge denied Caldwell’s pretrial motion for an additional examination by a particular psychiatrist,
Caldwell’s argument is erroneous for more than one reason. The only matter before the court at the time of his request was whether he was competent to stand trial. When the trial court is satisfied that it can resolve the issue of competence without additional appointments, we cannot construe the failure to do so as a denial of expert assistance for a substantive defense of insanity.
The purpose and nature of [an] appointment [under the Criminal Justice Act80 ] is entirely different from an examination conducted by an order of the court. The latter is conducted to serve the court in a completely nonpartisan manner. While the opinions of such an expert may assist one side or the other in a case, this is not the primary purpose for the expert’s appointment. The expert appointed under [the Act], however, is not originally and primarily an aid to the court, but rather is intended to serve the interest of the defendant.81
Equally pertinent to the dispute is the fact that Caldwell never informed the
Beyond these considerations, there is another major flaw in Caldwell’s current argument. The complaint is that, because Dr. Maguigad was not appointed additionally as an examining psychiatrist for purposes of the competency determination, Caldwell suffered from the lack of Dr. Maguigad’s testimony at the trial. This reasoning simply does not withstand scrutiny. On the one hand, the psychiatrist’s service at the pretrial stage was no assurance of further service at the trial stage. On the other hand, despite nonappointment earlier, the psychiatrist was appointable and callable at trial.
Quite apart from the foregoing contention, Caldwell sets forth the additional claim that the prosecution, in violation of a discovery order,
Our task would be simpler if we had before us a complaint involving material ordinarily discoverable under the Federal
The decision on this question must turn upon whether Caldwell’s letter and note were “statements” of the type contemplated by Criminal Rule 16(a),
We find the Government’s position unacceptable. The courts have rejected arguments that the “statements” discoverable under Rule 16(a) are only those made to governmental agents,
Still, we must determine whether the use the Government made of the correspondence at trial was prejudicial, for if not the nonproduction cannot affect Caldwell’s conviction.
B. The Insanity Defense: Timm
[25] Presenting his insanity defense in turn, Timm utilized testimony by a clinical psychologist, Dr. Carl Bauer.
Our starting point is our decision in Jenkins v. United States,
[t]he determination of a psychologist’s competence to render an expert opinion based on his findings as to the presence or absence of mental disease or defect must depend upon the nature and extent*1354 of his knowledge. It does not depend upon his claim to the title “psychologist.” And that determination, after hearing, must be left in each case to the traditional discretion of the trial court subject to appellate review. . . . When completion of [graduate] training is followed by actual experience in the treatment and diagnosis of disease in association with psychiatrists or neurologists, the opinion of the psychologist may properly be received in evidence.102
Basically, Timm argues that the judge’s decision to prohibit the sought-after testimony “was not based upon an analysis of his particular qualifications,” as directed by Jenkins, “but on a belief that such questions were ‘psychiatric questions’ and thus could not be answered by a psychologist.”
Terming the ruling “arbitrary and erroneous,”
From an examination of the record, however, we discern adequate support for the judge’s ruling. Phrased most simply, Dr. Bauer had already testified to the outer limit of the factual basis for any opinion he might express. He could not properly have been permitted to proceed beyond the parameters of what he actually knew about Timm.
The test for admitting expert opinion is whether it will appreciably aid the trier of fact in determining the factual is
Another contention by Timm in this area
To successfully invoke the Fifth Amendment privilege against self-incrimination, the danger of incrimination “must be real and appreciable . not a danger of an imaginary and unsubstantial character . .”
We think that to invoke the privilege it was not necessary as a precondition to assertion of the privilege, for Ms. Fletcher to demonstrate that she would have been forced to admit guilt, or that incidental parts of her testimony would have sealed a future conviction. As the Supreme Court has stressed:
The privilege afforded not only extends to answers that would in themselves support a conviction . but likewise embraces those which would furnish a link in the chain of evidence needed to prosecute the claimant .... To sustain the privilege, it need only be evident from the implication of the question, in the setting in which it is asked, that a responsive answer to the question or an explanation of why it cannot be answered*1356 might be dangerous because injurious disclosure could result.114
In the circumstances here, “we cannot say that the possibility of further incrimination was so remote as to deprive appellant of [her] fifth amendment rights.”
V. SEVERANCE OP CO-DEFENDANTS
Not surprisingly, the issue of severance
must show more than the fact that co-defendants whose strategies were generally antagonistic were tried together. At the very least, it must be demonstrated that a conflict is so prejudicial that differences are irreconcilable and ‘that
If it appears that a defendant or the government is prejudiced by a joinder of offenses or of defendants in an indictment or information or by such joinder for trial together, the court may order an election or separate trials of counts, grant a severance of defendants or provide whatever other relief justice requires. In ruling on a motion by a defendant for severance the court may order the attorney for the government to deliver to the court for inspection in camera any statements or confessions made by the defendants which the government intends to introduce in evidence at the trial. the jury will unjustifiably infer that this conflict alone demonstrates that both are guilty.’118
The first point raised in this regard concerns the presentation of Timm’s insanity defense. Timm called as witnesses Dr. Jonas Rappeport and Dr. Leonardo C. Maguigad, both of whom were expected to testify that Timm’s criminal acts resulted in part from Caldwell’s influence. The trial judge refused to let either expert refer specifically to Caldwell as the person responsible supposedly for Timm’s participation in the robberies. Just as he characterized the judge’s ruling with respect to Dr. Bauer,
We analyze the issue in two steps: first, whether the trial judge improperly restricted this testimony,
Once again we see an attempt to offer conclusory expert testimony that has no apparent factual basis.
[S]ome of my final conclusions . are based on my feeling that Mr. Caldwell had the capability from the little I know or that Mr. Timm may have been influenced unfavorably by someone else and may have been influenced to do this and on the basis of one letter that I have, there seems to be some indication that Mr. Caldwell is the type of person who is quite capable of influencing him. (emphasis added).
We are convinced that as a matter of law there was an insufficient factual basis for this witness’ potential testimony.
Where Timm’s second witness, Dr. Maguigad, is concerned, a similar deficiency unfolded at trial. He admitted in testimo
Timm now contends that the restriction on this line of testimony, assertedly necessary also to protect Caldwell’s rights,
Without equivocation, we have held that
[t]he decision to grant a severance of defendants properly joined for trial is one over which the trial court possesses great discretion and exercise of that discretion will be reversed on appeal only when it is shown to have been clearly abused. The general rule is that defendants charged with jointly committing a criminal offense are to be jointly tried.129
This general rule finds justification in a number of considerations. The joint trial
‘expedites the administration of justice, reduces the congestion of trial dockets, conserves judicial time, lessens the burden upon citizens who must sacrifice both time and money to serve upon juries, and avoids the necessity of recalling witnesses who would otherwise be called upon to testify only once.’130
The essence of the trial judge’s duty on a motion for severance is to determine wheth
The denial of the severance motion in the case at bar was not an abuse of discretion. A variety of factors had to be weighed in determining whether Timm and Caldwell should remain together in a single trial until the very end. The trial had already begun, after many months of hearings, examinations, witness-interviews and preparations by the court as well as by the lawyers involved. Potential jurors for any future retrials had been exposed to whatever news coverage ensued after sequestration of the original jury. Moreover, despite the lack of coordination between the two codefendants, their witnesses were able to make their basic positions clear to the jury. In light of appellants’ contentions that they suffered from pretrial publicity,
The second reason for severance, urged by both appellants, is that the case was too complex for the jurors to understand because of two insanity defenses and varying psychiatric explanations. Additionally, appellants assert that the presentation of the evidence was overly fragmented, and that the Government’s rebuttal did not sufficiently distinguish between the two appellants.
This issue was raised at trial only once, when the judge denied a request for a cautionary instruction during the Government’s rebuttal, stating her intention to so instruct at the close of trial. At that time the jurors were admonished that they were to determine guilt, innocence, or lack of guilt by reason of insanity as to each defendant separately, and that evidence admitted solely as to one defendant could not be considered against the other. This instruction was one of the last given to the jurors just prior to the beginning of their deliberations.
In their final arguments demanding reversal on account of insanity-related rulings, each appellant claims that the conduct of the other cast doubts upon the genuineness of his insanity defense. Caldwell points to Timm’s verbal interruptions of the proceedings; and Timm cites Caldwell’s “trance” during various periods of trial, particularly during the Government’s rebuttal. So far as Caldwell’s actions are concerned, we are cited to no specific facts tending to show that his strange behavior worked to the detriment of Timm. All we are told by counsel is that “[i]f the jurors concluded from their observations of Caldwell during the remainder of the trial that his defense was a sham[,] [t]hey might well have been misled into believing that Timm’s defense also was insubstantial.”
Caldwell likewise claims that the jury could have viewed him as a malingerer because of Timm’s yelling and verbal remarks at the prosecutor and at various witnesses. But here again Caldwell fails to set forth anything to show how these occurrences, without more, damaged his defense, and we cannot hold without an adequate factual basis that there was a carryover effect. Timm’s behavior in the courtroom was not beyond the bounds of what might reasonably be expected at a trial of any defendant seeking to persuade the jury that he is mentally unbalanced. To win severance, a codefendant “must show that substantial prejudice derives from the joint trial and not merely that he would have had a better chance of acquittal were he tried separately.”
VI. THE PROSECUTOR’S SUMMATION
Appellants have articulated several complaints about the prosecutor’s closing argument, charging him with “belittling” their expert witnesses and improperly characterizing the insanity defenses. Our scrutiny of what was actually said, in proper context, unearths no error as to verbal remarks or prosecutorial behavior.
A. Closing Argument Regarding Caldwell
Under the canopy of “belittling” expert witnesses, Caldwell describes two instances in which government counsel allegedly ridiculed testimony by Dr. Whyte, a witness for Caldwell,
Similar criticism is leveled against the Government’s repetition of the view expressed by Dr. Whyte as to the significance of the letter written by Caldwell in which he asked his friends for drugs.
Caldwell attacks this prosecutorial approach as “inconsistent with the very concept of psychiatry, whose function is to explore the hidden meanings of human behavior.” “The statements,” he says “amount to an attack on any defense grounded in this science.”
It is clear that the prosecution struck hard blows but not foul ones.
We may similarly dispose of Caldwell’s contention that there was no showing that Dr. Whyte’s construction of the letter
The episode in which the prosecutor labeled Caldwell’s defense a fraud involved a series of remarks, generally that it was “a big fake of a desperate person who has no other conceivable defense.” Caldwell argues that such comments to the jury were inflammatory and prejudicial, because Caldwell’s expert witness testified that he had considered and rejected the possibility of malingering and that he ultimately concluded that Caldwell really was mentally ill. We say unhesitatingly that a prosecutor is not precluded from challenging the genuineness of an insanity claim simply because a defense witness has himself rejected the view that the defense is feigned. Our adversary system of conducting criminal trials encompasses no device whereby the accused is forever insulated from attack by offering a witness whose opinion undertakes to refute facts and circumstances in evidence which support a contrary theory of the case.
Here the prosecution’s argument did not lack evidentiary support. Caldwell’s defense of insanity was called into question, not for the first time in summation, but much earlier during the trial itself. That was accomplished partly through the testimony of a fellow inmate at the jail, who pictured Caldwell as behaving normally, as well as by circumstances such as the letter and the note Caldwell endeavored to send to his friends.
B. Closing Argument Regarding Timm
Timm’s first accusation
We are not persuaded that such argument was impermissible. In truth, there was some evidence of malingering, and it was for the jury to decide what if any weight would be attached to it. The trial judge fully appreciated the possibility that some testimony might have been referred to out of context; and she prudently instructed the jurors that counsels’ summations were intended to include only what they deemed deserving of special attention, and that the jurors’ recollection of the evidence, not counsels’ was controlling.
Another line of witness-questioning was also reiterated by the prosecutor in closing argument. During the course of administering a number of psychological examinations, Dr. Bauer employed what is colloquially known as the “house-tree-person” test. Basically, it consists of directing the patient to draw each of those three figures and inferring therefrom his feelings about himself and society. Based on this examination and others, Dr. Bauer concluded that Timm was suffering from a mental disease. Quite candidly, Dr. Bauer stated:
I would not wish the Court to think that on the basis of that drawing in itself I would draw any conclusion of any consequence.
It is one of the blocks in the information which I have gathered. It is significant in that it does correlate with all the other information.
The prosecutor, however, attempted to condense Dr. Bauer’s entire testimony, saying “[a]nd yet, according to him, because Timm drew a figure like this, Timm is mentally ill.”
Caldwell now contends that the essence of this witness’ testimony was distilled by the prosecutor to such a form that it placed disproportionate emphasis upon one of the psychological examinations. We believe, however, that the prosecutor’s argument did not provide that much of a twist. While the prosecutor’s language was somewhat exaggerated, and while several steps in Dr. Bauer’s process of deduction were omitted, nevertheless the statement by government counsel appeared to be little more than an expression of the net result of Dr. Bauer’s examinations.
There is a third point which by our assessment is no more substantial in nature. According to the prosecutor’s summation, the only examination from which Dr. Bauer found evidence of Timm’s dependency needs was the handwriting or graphology test.
Lastly, we are urged to find reversible error in what is viewed as an attempt to use evidence admitted only as to Caldwell to rebut the insanity defense advanced by Timm. To recapitulate the pertinent testimony, Dr. John R. Cavanaugh was called to the witness stand by the Government during rebuttal. At one point he replied to the prosecutor on direct examination “that the quiet, calm, peaceful attitudes of the indi
In light of the court’s ruling on the initial objection, permitting the reference to both individuals was error. But we are mindful of several other items which in any event save the prosecutor’s comments from being more than harmless error. Dr. Cavanaugh was not attempting, at the time of his remark, to present a psychiatric diagnosis of Timm, but merely a categorical observation which might well have been rested upon evidence already adduced. Nothing the observation assumed with respect to Timm was a fact not in evidence;
In sum, our review of these aspects of the Government’s summation shows that essentially they were direct appeals to the cornmon sense of the jurors.
VII. INSTRUCTIONS TO THE JURY
According to both appellants, the trial judge erred in fashioning instructions for the jurors in each of three different areas of the litigation. The first two complaints involve the denial of requested instructions on specific aspects of the case; the last is more realistically an argument against the assignment to appellants of the burden of proving the insanity defenses they sought to erect.
Caldwell submitted to the judge a proposed instruction on second degree murder which stated that, if he were convicted, the punishment would be “up to life, or not less than twenty years.” The judge declined to employ such a statement in the charge to the jury. Addressing its more obvious shortcoming, the Government points out that the request, as so phrased, incorporated an inaccurate representation of the law, for the proposed wording implied that a person found guilty of second degree murder would be incarcerated for at least twenty years. An instruction informing the jury of sentencing possibilities would have correctly stated that the minimum range of actual confinement, in terms of parole eligibility, is from one day to one-third of twenty years.
In point of fact, the trial judge did charge the jury on the elements of second degree murder, as a lesser included offense of first degree murder, but the underlying
Timm requested an instruction relating to an incident which occurred on cross-examination of one of his expert witnesses. During questioning by the prosecutor, Dr. Maguigad testified that he had been retained by Timm’s father; when asked whether his fee had been paid prior to his appearance in court, he answered in the negative. Thereupon Timm’s counsel objected at the bench, urging that such a line of inquiry was irrelevant. The court agreed, but responded that it would “just . let the whole thing lie,” and the matter was pursued no further at that time. At the close of the case, however, Timm asked that the jury be instructed “on the fact that expert witnesses are entitled to be paid for their services.” In denying this request, the trial judge concluded that it was “not necessary at this point.”
We sympathize with Timm’s apprehension that jurors might have concluded that, since he had not been paid, Dr. Maguigad’s compensation would depend on the success of his testimony. And we think that the better practice would have been to give a cautionary instruction immediately following such an improper question. As to Timm’s request for the instruction just pri- or to the jury’s retirement for deliberations, the judge estimated that the impact of the question had been dissipated by the lapse of time between its asking and the charging of the jury; in short, that remark was of a minor nature in the context of a three-week trial, and perhaps more harm would have been done by dredging the subject up once again. On this point we defer to the trial judge’s evaluation, based as it was upon first-hand observation of the entire range of events which transpired during the trial.
The final contention goes to the substance of the instruction on burden of proof of insanity. The question is whether the court properly charged that appellants had to establish their insanity defenses by a preponderance of the evidence for both the federal and the District of Columbia code offenses on trial.
In this court’s decision in United States v. Greene,
We deem it unnecessary, however, in the circumstances presented, to resolve on the merits that issue in the instant case. We note, on the one hand, a serious and complex constitutional question with no controlling precedent directly in point, and the toll its decision will take on the court’s resources at this time. On the other hand, we note the interrelationship of numerous convictions of appellants stemming from facets of two separate but internally integrated criminal episodes,
To recapitulate, Timm incurred nine nonfederal convictions, and Caldwell eight, on which each was sentenced to incarceration for terms extending upwardly to life imprisonment.
Pour years ago, we faced a cognate situation in United States v. Hooper,
We think these considerations chart the same course here. Accordingly, we vacate the federal convictions and the sentences levied upon appellants.
. The convictions, and the sentences respectively imposed, were as follows:
On counts 1, 7 and 11, for federal bank robbery, 18 U.S.C. § 2113 (1970) five to fifteen years’ imprisonment (both appellants). On counts 2, 8 and 12, for armed robbery, D.C.Code §§ 22-2901, 22-3202 (1973), five to fifteen years’ imprisonment (both appellants).
On counts 4, 10 and 14, for assault with a dangerous weapon, D.C.Code § 22-502 (1973), two to eight years’ imprisonment (both appellants).
On counts 5 and 18, for carrying an unlicensed pistol, D.C.Code § 22-3204 (1973), one year’s imprisonment (appellant Timm).
On count 6, for felony-murder, D.C.Code § 22-2401 (1973), life imprisonment (both appellants).
On counts 15 and 16, for federal firearms violation, 26 U.S.C. §§ 5861(d), (i), 5871 (1970), two to eight years’ imprisonment (both appellants).
On count 17, for carrying an unlicensed pistol, D.C.Code § 22-3204 (1973), one year’s imprisonment (appellant Caldwell).
All sentences were designated for concurrent operations except those on counts 7 and 11, which are to be served consecutively to the sentence imposed on count 1.
. In Part I, we discuss, the factual background of the robberies and the trial itself. Part II summarizes our holdings with respect to pretrial publicity and the conduct of the voir dire. In Part III, we analyze the issues concerning the pretrial competency determination of Caldwell. Part IV is an extensive discussion of issues affecting the presentation of the insanity defenses. In Part V, we address problems relating to severance of the codefendants. Encompassed in Part VI are our views on the conduct of the prosecutor’s summation. Finally, in Part VII we explore the various claims of error as to the final instructions to the jury. There also we capsulize our dispositions of the convictions.
. The precise disposition, by counts of the consolidated indictment, is set forth in Part VII at notes 191-195, infra.
. The parties’ statements of the facts of the case without repetition or undue elaboration, consume a total of 187 pages of their briefs.
. The prosecution and the defense stipulated that this institution is a corporation and that its accounts were insured by the Federal Savings and Loan Insurance Corporation. See 18 U.S.C. § 2113(g) (1970). A similar stipulation was made as to National Permanent Federal Savings and Loan Association, the other institution robbed.
. The branch manager, Jean Wells, noticed them but assumed that they were police officers. She testified that
[t]hey were very assured. I think that is the reason my judgment said they might be policemen when they walked in. They were extremely observant, self-assured. They seemed very deliberate in their actions.
. Timm and Caldwell were first linked to the American Savings robbery when they were recognized coincidentally the next day by Officer Gosnell as he assisted in their arrest for the second robbery.
. See note 1, supra.
. For example, Officer Schwartz also began to return fire. At one point, he took aim at Timm but held fire to avoid hitting a civilian walking behind Timm.
. Ms. Fletcher was separately indicted as co-defendant of Timm and Caldwell for the offenses of May 25. In December, 1971, before the case was reached for trial, she entered a plea of guilty to those charges, and was sentenced under the provisions of the Federal Youth Corrections Act, 18 U.S.C. §§ 5005 et seq. (1970).
. Timm, wounded and barely conscious, was found lying in the back of the truck.
. These included a briefcase containing $7,958, some of which was the bait money; a .45 caliber automatic pistol identified as the one from which had been fired the shot killing Officer Sigmon, and cartridge cases and mutilated bullets found at the scene; a copy of a magazine, bearing Timm’s fingerprints, which had been removed from Ms. DuTeil’s desk; a cache of guns and ammunition, among which was an unregistered sawed-off shotgun from which the serial number had been removed; and wigs and other makeup paraphernalia. In Caldwell’s pocket was a loaded handgun and an expended .38 caliber projectile identified as having been fired from Officer Bishop’s gun.
. See text infra at notes 14-17.
. Police officers had located various articles of clothing which appellants had worn during the robberies. These included a gold jacket worn by Caldwell and wigs worn by each. See note 12, supra. Various witnesses described for police, and later identified in court, these items of outerwear.
. See note 10, supra.
. See note 1, supra.
. Perhaps the most interesting and pertinent examples were (a) the deputy medical examiner who verified the cause of death; (b) the ballistics expert who identified the bullet as coming from Timm’s .45 automatic, and who matched the indentations of the nose of the death bullet with those of Officer Sigmon’s belt buckle; and (c) the technician who correlated hair fibers of Caldwell and Timm with those found on the wigs taken from the truck.
. “In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law . . . .” U.S.Const. amend. 6.
. See note 10, supra.
. The standard for granting a change of venue in the federal courts derives from Fed.R. Crim.P. 21(a), which reads:
The court upon motion of the defendant shall transfer the proceeding as to him to another district whether or not such district is specified in the defendant’s motion if the court is satisfied that there exists in the district where the prosecution is pending so great a prejudice against the defendant that he cannot obtain a fair and impartial trial at any place fixed by law for holding court in that district.
. In December, 1972, within days after the entry of Heidi Fletcher’s plea of guilty, see note 10, supra, Caldwell alone moved for a change of venue, claiming prejudice from publicity over the plea. No supporting documentation was filed to describe media accounts of Ms. Fletcher’s new status, and the trial judge rightly denied the motion. A change of venue cannot be grounded merely upon a codefendant’s entry of a plea of guilty prior to trial. The rationale is much the same as that underlying decisions that such an occurrence does not constitute ground for a mistrial if an adequate cautionary instruction is given. See United States v. Dardi, 330 F.2d 316, 332-333 (2d Cir.), cert. denied, 379 U.S. 845, 85 S.Ct. 50, 13 L.Ed.2d 50 (1964); United States v.

In a widely publicized or sensational civil or criminal case, the court, on motion of either party or on its motion, may issue a special order governing such matters as extrajudicial statements by parties and witnesses likely to interfere with the rights of the accused to a fair trial by an impartial jury, and any other matter which the Court may deem appropriate for inclusion in such an order (emphasis in original)
This rule is identical to the former Rule 100, which was in effect at the time of trial.
. See note 3, supra.
. Several proceedings were held in camera. We cite, for example, Heidi Fletcher’s motion concerning her bail status, held August 29, 1971, and Timm’s motion to have Ms. Fletcher return to testify at trial, heard on February 17, 1971.
. Typical of the remarks under complaint was the description by a District of Columbia Department of Corrections spokesman of a suicide attempt by Caldwell while in custody.
. A prime example of a prosecution position appearing in the press are accounts of the prosecution’s belief that appellants were faking insanity. This viewpoint was extrapolated from arguments presented in open court and pleadings filed with the court in the normal course of litigation. It will be recalled that the jury was then sequestered, as it was throughout the trial.

. We repeat that the jury was sequestered for the duration of the trial.
. That appellants were the perpetrators of the crimes being tried was never disputed at any point in the case.

Bernard, 198 F.2d 96 (9th Cir. 1952). In Bloeth, the accused was tried for his suspected commission of an alarming series of murders in a suburban New York county. The Second Circuit Court of Appeals remanded the case for a new trial based upon the conduct “from the prosecution denigrating the insanity defense and so predisposing the prospective jurors to reject it.” 313 F.2d at 373. Further, said the court, “[t]he opinions formed in this case, moreover, were based not solely on accounts of the crime at issue, but on . . expressions of the disbelief of the District Attorney in the lack of sanity of the defendant, with editorial attack upon the possibility of a legal loophole that by the defense of insanity would free the mad killer to strike again.” Id.
Similarly, in Fouquette, the Chief Judge of the Ninth Circuit ordered a stay of execution following a murder conviction, finding probable cause that local prejudice had precluded a fair trial. In this instance, the pretrial publicity included improper press interviews by both the District Attorney and the judge who was later to try the case. The prosecutor described at length “how he framed a second confession he obtained from Fouquette to rebut his defense of insanity.” 198 F.2d at 99. For his part, the trial judge expounded in the same county newspaper upon “how under the Nevada law the ‘citizenry’ well could be exposed to future danger if Fouquette were acquitted on the ground of insanity.” Id. We hasten to say that there was no such behavior in the case at bar.

United States, supra, 400 F.2d at 638; see also United States ex rel. Bloethe v. Denno, supra note 38, 313 F.2d at 372.
. The first complaint involves a prospective juror who came to the bench in response to the judge’s question as to how much any of them knew about the robberies. The offending remark, according to appellants, was that “they brought Fletcher in.”
Later, a second potential juror approached the bench to answer more fully the judge’s query as to whether anyone believed that insanity should not be held to be a defense to a serious and violent crime. Appellants characterize as prejudicial the juror’s statement, “[wjell, I don’t feel they should hide behind the plea of insanity, Your Honor.”
. With the first of the two potential jurors, the following questions evolved:
THE COURT: Well, did you form any opinion as to these defendants as a result of reading about Heidi Fletcher?
POTENTIAL JUROR: No, because I didn’t — I think the reason I paid more attention to her was because of her father being here in the District, and the other two defendants I didn’t know anything about it and I never paid any attention to the case.
THE COURT: If you were selected on the jury would you be able to determine the case, the guilt or innocence of the defendants, based solely on the evidence produced in the case rather than any impression from anything you have read, seen, or heard?
POTENTIAL JUROR: Yes, Your Honor. I think I would.
THE COURT: If you were a defendant, would you want you as a juror?
POTENTIAL JUROR: I see no reason why I wouldn’t.
The following colloquy ensued between the court and the second individual:
THE COURT: Would you tell us how you mean that, what is your reason that you feel it is not a proper defense?
POTENTIAL JUROR: Well, I don’t feel they should hide behind a plea of insanity, Your Honor.
THE COURT: Suppose they are proven by testimony of psychiatrists and competent witnesses that they are suffering from or were suffering from a mental disease or defect which caused them to do the thing—
POTENTIAL JUROR: Then I would have to abide by those findings.
THE COURT: Do you feel you would be hesitant to find in that way?
POTENTIAL JUROR: Not if they were proved to be insane.
THE COURT: I would like to tell you that the burden is upon the defense to establish, by a preponderance of the evidence, that the defendants are suffering from a mental disease or defect.
Would you be able to follow the instructions with regard to that or would you feel that you would be basically prejudiced on that plea?
POTENTIAL JUROR: I feel I would be able to follow through with the instructions.
THE COURT: Very well, you may resume your seat.

. Caldwell deems this hearing inadequate because, inter alia, the trial judge failed to order further mental examinations, sua sponte, and allegedly ignored defense counsel’s statement that he was unable to communicate with appellant. We reject these arguments. Caldwell has no reasonable basis to urge such complaints on appeal because all witnesses who testified were specifically requested by Caldwell’s counsel — indeed, they were only persons whose appearances were demanded — and the judge’s explicit offer to call others was declined. Moreover, uncooperativeness with one’s counsel does not alone prove an inability to communicate. We discern no error in the judge’s failure to expand the inquiry any further on her own motion; neither do we see error in the absence of specific reasons given for her decision.
. Caldwell’s counsel represented that Caldwell was and, since arrest had been in a trance-like state, unable to eat, talk or perform basic tasks for himself. The facts adduced at the competency hearing indicated quite the opposite. The Government called three witnesses, one of whom was an inmate, Prince A. Sham non, who had helped to care for Caldwell in the jail’s infirmary. Shannon stated that during this alleged trance Caldwell ate solid food, stole food from others, bathed himself, helped a fellow inmate to learn to read, and wrote a letter and note which he asked Shannon to pass on to friends outside the jail. Similar testimony was given by a registered nurse who observed Caldwell at the jail. The final government witness was Dr. Elizabeth Strawinsky, who concluded on the basis of Caldwell’s medical records and conversations with him that he was capable of communicating with others if he chose to do so.

. What Caldwell mainly contests is the propriety of the court’s acceptance of the lay testimony offered by the Government. It has long been the law in this circuit that layman may testify as to “insanity.” See, e. g., United States v. Pickett, supra note 66, 152 U.S.App.D.C. at 348, 470 F.2d at 1257 (1972); Tatum v.

. Brief of Appellant Caldwell at 89.
. Caldwell as hospitalized there shortly after his arrest, from May 28 to June 24, 1971.
. The expert referred to is Dr. Alec Whyte. See text infra at notes 85-98.
. The court was generous in its appointment of several experts to aid Caldwell with preparation of his insanity defense.
. Criminal Justice Act of 1964, Pub.L. No. 88-455, 78 Stat. 552 (1964), as amended, 18 U.S.C. § 3006A (1970), legislation “designed to provide indigent defendants in criminal cases with representation and expert service. It is clear that the Act comprehends within its definition of ‘expert services’ the assistance of a psychiatric expert in preparing and presenting an insanity defense.” United States v. Chavis, supra note 75, 155 U.S.App.D.C. at 194, 476 F.2d at 1141. See also United States v. Taylor, 437 F.2d 371, 377 (4th Cir. 1971); United States v.

. The record reveals that during trial, at a hearing outside the presence of the jury, Dr. Maguigad admitted, under questioning by Caldwell’s counsel, that he had seen Caldwell for only ten minutes during the process of admitting him to Saint Elizabeths Hospital. This revelation occurred during Caldwell’s attempt to show that Dr. Maguigad, then a witness for Timm, lacked sufficient knowledge to testify as to Caldwell’s alleged influence on Timm. This evidence leaves Caldwell’s contentions curious indeed.
. We might add that even if Dr. Maguigad had testified, the Government unquestionably retained the right to cross-examine all other witnesses for Caldwell.
. In November, 1971, the trial judge ordered pretrial discovery in accordance with the specifications of Caldwell’s written motion. In pertinent part, the order covered
all written or recorded statements made by the defendants [including] . . statements made to witnesses other than police officers at any time the defendants were in custody . . . ; all . . documents obtained during the investigation of this case that may be used as evidence herein . . ; and any . . . papers [or] documents . . which the prosecuting attorney intends to use in a hearing or trial or which were obtained from or belong to the accused.
. In the letter, written to a group of his friends in Virginia, Caldwell stated:
I am well in spite of outward appearances . I need about ten ‘Lysergics’ so I can pass my head test with flying colors. A woman will call you and ask for ‘Vic’s perscription’ [sic] or you’ll know her by the use of that name . . .. Ask Charlie to let me know when the test is going to occur.
The note, passed to a sixteen-year old inmate in the jail infirmary to be relayed to another inmate, showed Caldwell asking “them to get 5 to 10 LSD trips to me.”
. See note 86, supra.
. In its entirety, Rule 16(a) reads:
Upon motion of a defendant the court may order the attorney for the government to permit the defendant to inspect and copy or photograph any relevant (1) written or recorded statements or confessions made by the defendant, or copies thereof, within the possession, custody or control of the government, the existence of which is known, or by the exercise of due diligence may become known, to the attorney for the government, (2) results or reports of physical or mental examinations, and of scientific tests or experiments made in connection with the particular case, or copies thereof, within the possession, custody or control of the government, the existence of which is known, or by the exercise of due diligence may become known, to the attorney for the government, and (3) recorded testimony of the defendant before a grand jury.
See generally United States v. Addonizio, 451 F.2d 49 (3d Cir. 1971), cert. denied, 405 U.S. 936, 92 S.Ct. 949, 30 L.Ed.2d 812 (1972).
. See note 88, supra. See also, e. g., United States v. Aadal, 407 F.2d 381 (2d Cir.), cert. denied, 395 U.S. 967, 89 S.Ct. 2114, 23 L.Ed.2d 754 (1969).
. See note 88, supra. See generally, Note, Discovery by a Criminal Defendant of His Own Grand-Jury Testimony, 68 Colum.L.Rev. 311 (1968).
. “The duty of disclosure affects not only the prosecutor, but the Government as a whole, including its investigative agencies.” United States v. Bryant, 142 U.S.App.D.C. 132, 140, 439 F.2d 642, 650 (1941). See also, e. g., United States v. Rosenberg, 299 F.Supp. 1241 (S.D.N.Y.1969) (transcripts of conversations with Internal Revenue Service official on occasions of alleged bribes); United States v. Mosely, 266 F.Supp. 834 (S.D.N.Y.1967) (defendant’s statement to postal inspectors).
. See note 88, supra.
. We cannot agree with our dissenting colleague that Caldwell’s letter and note were not “relevant” within the meaning of Rule 16(a). As applied to the accused’s own damaging statements, the requirement of relevance “seems superfluous in view of the obviously vital importance of the material sought.” 8 J. Moore, Federal Practice fl 16.05 [1] at 16-32 (2d ed. 1965). See also Xydas v. United States, 144 U.S.App.D.C. 184, 188-189 n. 9, 445 F.2d 660, 664-665 n. 9, cert. denied, 404 U.S. 826, 92 S.Ct. 57, 30 L.Ed.2d 54 (1971); 1 C. Wright, Federal Practice §§ 251-53 (1969). The fact that the materials were used for impeachment and rebuttal does not make them any the less relevant. Caldwell’s statements, in the context of his insanity defense, were by no means “tangential” or “ ‘beside the point’ matters,” but were tantamount to a confession of mental soundness.
. Rule 16(a) encompasses the accused’s “recorded” as well as “written” statements in the Government’s possession, see note 88, supra, and recorded conversations between the accused and persons other than governmental agents are within the rule. United States v. Crisona, 416 F.2d 107, 114-115 (2d Cir. 1969), cert. denied, 397 U.S. 961, 90 S.Ct. 991, 25 L.Ed.2d 253 (1970); Davis v.

. Dr. Bauer, at the time, was a member of the staff of Saint Elizabeths Hospital. He saw Timm eight to twelve times and administered such commonly-known tests as the Rorschach, in addition to a handwriting or graphology test. His expert qualifications as a clinical psychologist were not challenged by the Government.
. This effort is related also to another issue on appeal. See Part V, infra.

. See Blunt v. United States, supra note 102, 128 U.S.App.D.C. at 379, 389 F.2d at 547 (footnote omitted).
. The trial judge observed that Dr. Whyte “has already expressed a great deal of information which I think was proper under his qualifications and the results of the tests which he is skilled in administering.” The court was convinced that the witness had taken his information as far as he could. See generally, Jenkins v. United States, supra note 101; United States v. Riggleman, 411 F.2d 1190, 1191 (4th Cir. 1969). We discuss the need for an adequate factual basis for a psychiatric opinion more fully in Part V, infra.
. Compare Strickland v. United States, 115 U.S.App.D.C. 5, 316 F.2d 656 (1963). Reacting to facts similar to those of the instant case, we upheld the trial court’s disallowance of a psychologist’s testimony because the witness “did succeed in expressing his opinion at some length”, because “counsel made no clear proffer or objection” and because other defense experts had full access to the test results obtained by the psychologist. Id. at 6, 316 F.2d at 657. We do not mean to say that a psychologist’s testimony can be excluded merely because his test results are available to other witnesses. It is, however, one of many factors going to a determination of prejudice.

In light of this disposition, we cannot hold that the Government’s failure to grant Ms. Fletcher immunity from prosecution for the May 21 and 24 robberies was a withholding of exculpatory material within the requirements of Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963). We note, in the same vein, that there was no general right to a grant of governmental immunity to Ms. Fletcher to secure her testimony in Timm’s behalf. Earl v. United States, 124 U.S.App.D.C. 77, 361 F.2d 531 (1966), cert. denied, 388 U.S. 921, 87 S.Ct. 2121, 18 L.Ed.2d 1370 (1967).

. See Part 1V(B), supra.
. We use the word “restricted” because the trial judge did not literally stop the effort to attribute influence over Timm to another person. Rather, the judge cautioned Dr. Rappeport to
indicate that [Timm] is impressionable, or however you would put it, and subject to influences of others and leave it that vague even if they assume that it was the other defendant, co-defendant, that is, Heidi Fletcher. It’s immaterial but it cannot be thought to be Mr. Caldwell, at least it can’t be brought out in that fashion.
. The burden rests upon the moving defendant to demonstrate prejudice from the denial of a motion to sever. See United States v. DeSapio, 435 F.2d 272, 280 (2d Cir. 1970), cert. denied, 402 U.S. 999, 91 S.Ct. 2170, 29 L.Ed.2d 166 (1971); United States v.

. Apparently no one made any effort to secure the personal appearance of Cooper at trial.
. Dr. Rappeport’s presence in court was not by any means a total loss. He did come forth with rather extensive and specific testimony on Timm’s social background, home life and the like, with ample support for his professional views.
. We have allowed psychiatric experts to base their opinions upon reports of others customarily relied on, such as reports of psychologists. See, e. g., Jenkins v. United States, supra note 101. But a psychiatric opinion may not be predicated on hearsay of the kind offered here. “ ‘Generally speaking, the opinion of a medical expert based upon information obtained out of court from third persons is inadmissible. The same rule is followed when the question is the sanity of the defendant.’ ” United States v. Bohle, 445 F.2d 54, 69 (7th Cir. 1971), quoting 2 Wharton’s Criminal Evidence § 519 at 344 (12th ed. 1955). See also People v. Keough, 276 N.Y. 141, 11 N.E.2d 570, 572 (1937); Seawell v. Brame, 258 N.C. 666, 129 S.E.2d 283, 287-288 (1963); 3 J. Wigmore Evidence, § 688 (Chadbourne rev. 1970). “[T]he party to be confronted by such an opinion should have the full opportunity of cross-examination,” United States v. Bohle, supra, 445 F.2d at 65, an obvious impossibility where the person who supplied the information is not present in the courtroom.
. See note 120, supra.
. The trial judge felt that there was such a necessity. Our holding that neither Dr. Rappeport nor Dr. Maguigad had sufficient factual foundations for the opinions Timm wanted them to state sustains the judge’s ruling in any event. Since, however, there is an alternative basis for the ruling, we discuss it.
. United States v. Gambrill, 146 U.S.App.D.C. 72, 83, 449 F.2d 1148, 1159 (1971). See also United States v. Hurt, 155 U.S.App.D.C. 217, 222, 476 F.2d 1164, 1169 (1973); Brown v.

And see Fed.R.Crim.P. 8(b), which reads:
Two or more defendants may be charged in the same indictment or information if they are alleged to have participated in the same act or transaction or in the same series of acts or transactions constituting an offense or offenses. Such defendants may be charged in one or more counts together or separately and all of the defendants need not be charged in each count.
Other courts as well have stated that the trial judge has wide latitude in granting or denying severance, and that an abuse of discretion must be shown in order to prevail upon a claim of error. See, e. g., Opper v. United States, 348 U.S. 84, 95, 75 S.Ct. 158, 99 L.Ed. 101 (1954); United States v. Brown, 335 F.2d 170, 172 (2d Cir. 1964); Tillman v.

. We note in passing other assertions by appellants that each was prevented from effectively developing his defense because of trial joinder — assertions we regard as even more plainly insubstantial. First, Caldwell states that because Timm placed upon him chief responsibility for the crimes, the joinder was prejudicial. But as we have outlined in text, Caldwell’s objections to potentially damaging testimony on that score were largely successful. See text following notes 116-122, supra. Second, Timm expresses criticism of his codefendant’s refusal to stipulate to “formal” testimony, a move which lengthened the parade of government witnesses relating incriminatory details. Timm’s motion to sever because of such refusals was correctly denied. As the Government explains, Caldwell did stipulate to various other facts; the remaining items to which the Government was willing to stipulate, but Caldwell was not, lengthened the trial only minimally; and the Government never agreed to stipulate to expert testimony, as was its right. No defendant can demand as of right a stipulation by his codefendant; the “general rule [is] that ‘[a] party is not required to accept a judicial admission of his adversary, but may insist on proving the fact.’ ” Parr v. United States, 255 F.2d 86, 88 (5th Cir.), cert. denied, 358 U.S. 824, 79 S.Ct. 40, 3 L.Ed.2d 64 (1958). See also United States v.

. Fed.R.Crim.P. 30 reads in pertinent part:
No party may assign as error any portion of the charge or omission therefrom unless he objects thereto before the jury retires to consider its verdict, stating distinctly the matter to which he objects and the grounds of his objection. Opportunity shall be given to make the objection out of the hearing of the jury and, on request of any party, out of the presence of the jury.

. Timm also adopts the arguments made by Caldwell but we reject these points for the reasons stated above.
. See note 157, infra.
. Caldwell also contends that the prosecutor improperly made light of Dr. Bauer’s method of psychological analysis, namely, inclusion of use of the graphology test. By definition, that examination is an interpretation of a person’s emotional makeup from handwriting characteristics, writing pressure and the like. We think the prosecutor was well within his right to criticize when he attempted to offset the importance of the test by telling the jury that it was not a standard intelligence test of the kind previously administered to Timm, and that it was a matter of personal interest to Dr. Bauer because it was the subject of his doctoral dissertation.
. See note 154, supra.
. In characterizing these remarks as harmless error, we do not regard the error to be serious enough to warrant a “prophylactic” reversal. See United States v. Bell, 165 U.S.App.D.C. 146, at 165, 506 F.2d 207, at 226 (1974).

Therefore, we held, jurors must be informed of the relevant consequences of such a finding, to supplement their common knowledge of the simpler verdicts of guilty and not guilty.

. See note 1, supra. Appellants also contend that the Federal Bank Robbery Act, codified in 18 U.S.C. § 2113 (1970), under which appellants jointly incurred three convictions, see note 1, supra, supersedes the general provisions of the District of Columbia Code and thus, they assert, bars prosecution under the latter for a felony-murder occurring in a federally-insured financial institution. We reject this position. In regard to the effect of passage of the Bank Robbery Act, the argument is contrary to general principles of prosecutorial discretion, Hutcherson v. United States, 120 U.S.App.D.C. 274, 277, 345 F.2d 964, 967, cert. denied, 382 U.S. 894, 86 S.Ct. 188, 15 L.Ed.2d 151 (1965), and the legislative history of the Act does not indicate a congressional intent to limit that discretion in this manner.

Concurrence in Part
(concurring in part and dissenting in part):
I concur in the foregoing opinion and the judgment but disagree with the majority’s assertion that the letter and note were discoverable under Rule 16(a), Fed.R.Crim.P. See Majority Op. at 1351. Such evidence, admitted and used solely in rebuttal for the purpose of impeachment, forming no part of the Government’s case-in-ehief, not material to the preparation of the defense and not material to the substantive crimes charged, is not a “relevant . . . statement” within the meaning of Rule 16.
As the court in Hodges quoted from Skill-man, upholding the admissibility of previously undisclosed recorded conversations of the defendant with a third person:
“[t]he recorded conversation was not a ‘relevant statement’ under the meaning of Rule 16. It was introduced not as a part of the government’s case-in-chief, but on rebuttal. ... It was not admitted for its truth, but was admitted solely for the purpose of [impeachment]. . There was nothing in the statement which had any bearing on the substantive crimes charged.”
480 F.2d at 232-233.
The same interpretation of Rule 16 was applied in United States v. Garrett, 305 F.Supp. 267 (S.D.N.Y.1969):
We have long construed Rule 16(a)(1), F.R.Crim.P., “as giving defendant almost automatic right to his written or recorded statements or confessions.” United States v. Federman, 41 F.R.D. 339, 341 (S.D.N.Y.1967). We adhere to the limitation expressed in Federman that defendant is not entitled to any tangential or “beside the point” matter he may have stated. Such irrelevant material, having no bearing at all on the crime charged, “may be put to good use in the pursuit of truth, including a test of defendant’s veracity.” Id. Cf. Advisory Committee’s Note, Rule 16(a)(1).
The majority opinion plays on words when it states that the letter was “tantamount to a confession of mental soundness.”
Supplemental Opinion on Appellants’ Petitions for Rehearing (D.C.Criminal Nos. 1420-71 & 1421-71).
Pending the Supreme Court’s decision in Mullaney v. Wilbur,
Mullaney’s significance to the instant case can be appraised only in the context of our application of Greene as the controlling precedent. Greene rested on Leland v. Oregon,
Appellants assert, however, that Winship and Mullaney have sub silentio set Leland for naught, and that in the case at bar we should so hold. In our view, we lack that prerogative. In Greene, the panel rejected a similar invitation,
In this milieu, it is not for us to declare the challenged statute unconstitutional on the theory that Leland is dead. Our duty is to abide Leland as long as the Supreme Court has not made its demise plain,
Petitions denied.
ORDER
Appellants’ suggestions for rehearing en banc and supplemental memorandum in support thereof having been transmitted to the full Court and there not being a majority of the Judges in regular active service in favor of having this case reheard en banc, it is
Ordered by the Court en banc that the aforesaid suggestions for rehearing en banc are hereby denied.
Statement of Chief Judge BAZELON in support of his vote to grant rehearing en banc.
The question presented by this petition for rehearing en banc is the extent to which recent Supreme Court decisions in Mullaney v. Wilbur
First, the Greene division interpreted Winship to require the prosecution to bear the burden of persuasion only with respect to “proof of facts — ‘the occurrence of an event’ ” and not with respect to “mental condition.”
Mullaney is also significant for its strikingly narrow description of the current status of Leland: “In Leland the Court declined to apply the specific holding of Davis —that the prosecution must prove sanity beyond a reasonable doubt — to the States.”
Most importantly, all of the considerations that underlie Mullaney — and Winship —compel the conclusion that the prosecution must bear the burden of persuasion with respect to insanity. Plainly stated the basic thrust of the two cases is simply that erroneous determinations of guilt or of the degree of culpability are intolerable.
We would be recreant to our duty as judges, if through a blind following of a decision which the Supreme Court itself has . impaired as an authority, we should deny protection to rights which we regard as among the most sacred of those protected by constitutional guaranties.
The court today concedes — and the case it cites admit — that Leland need not be followed if its demise is plain.

. The court noted in Leland that the issue of insanity as a defense to a criminal charge was considered by the jury only after it had found that all elements of the offense, including the mens rea if any required by state law, had been proven beyond a reasonable doubt. . . . Although as the state court’s instructions in Leland recognized, evidence relevant to insanity as defined by state law may also be relevant to whether the required mens rea was present, the existence or nonexistence of legal insanity bears no necessary relationship to the existence or nonexistence of the required mental elements of the crime. For this reason, Oregon’s placement of the burden of proof on insanity on Leland, unlike Maine’s redefinition of homicide in the instant case, did not effect an unconstitutional shift in the State’s traditional burden of proof beyond a reasonable doubt of all necessary elements of the offense.
