Thе appellants, Joseph Capone and Richard Murnane, were convicted by a jury of robbing the mail, assault, and conspiracy to do both. 18 U.S.C. §§ 371, 2 & 2114. Murnane was also convicted of possessing an unregistered sawed-off shot gun. 18 U.S.C. § 2; 26 U.S.C. § 5861(d). The appellants make several arguments attacking their convictions. We conclude that these arguments do not warrant reversals.
The main evidence at trial was provided by John Grider, an admitted accomplice in the crime, who was serving time in jail on a second-degree murder conviction arising out of unrelated activities. Grider was evidently persuaded to testify in this prosecution by a series of promises: he was promised “use” immunity; he was promised a letter from the prosecutor detailing his cooperation, for use when Grider became eligible for parole in six yеars; and he was promised that, should his life be endangered as a result of having testified, the Government would consider a transfer to another prison.
At trial, Grider described in detail the planning and execution of the robbery. According to Grider, the robbery was planned during a series of meetings in Somerville, Massachusetts, between the appellants, James Hackett, Peter Hackett, and himself. At these meetings, Capone provided information about the schedules of mail trucks and their contents, which he had obtained from his uncle, Joseph Bimber, who worked at the South Postal Annex in Boston. Capone also agreed to supply the guns for the robbery, and he reserved for his uncle and himself one-fifth of the expected profits. According to Grider, although Capone took part in the planning of the robbery, he did not takе part in the robbery itself.
Murnane, again according to Grider, did take an active part in the actual robbery. On the day of the robbery, June 16, 1975, Murnane drove the Hackett brothers and Grider in a stolen car to the South Postal Annex. While Murnane (with Peter Hackett) blocked the path of a mail truck attempting to leave the Annex by an access ramp, Grider • and James Hackett approached the truck with drawn guns. James Hackett climbed into the cab of the truck, Grider returned to the stolen car, and Murnane led the hijacked mail truck up Route 93.
As other testimony made clear, witnesses alerted the police, and two policemen, Officers Owen and Powers, pursued the hijacked mail truck. A gun battle ensued, in which Officer Owen, demonstrating considerable courage, was seriously wounded. All four attackers escаped on foot and could not immediately be located. Subsequently, four guns were recovered in or near the stolen car, which Murnane had driven.
Grider’s testimony was corroborated most significantly by the testimony of Larry Williams, Capone’s brother-in-law and a former police officer, who, before the robbery, had discovered a cache of guns in Capone’s sister’s barn, copied down the serial numbers, and relayed them to the police. The serial numbers given by Williams matched the guns recovered from the stolen car and another gun, a Walther PPK, which Grider admitted to using during this robbery and keeping afterward. Williams also testified *585 that a trencheoat, similar to one that Capone wore was stored in the barn with the guns. Officer Owen testified that the attacker who rode in the cab of the mail truck (James Hackett) wore a trencheoat and the driver of the hijacked mail truck described this same man as having a “barnyard smell.” The prosecution also entered into evidence several spent cartridges, discovered during a search of Murnane’s bedroom. Tests proved that these cartridges had been fired from the same Walther PPK that Williams had seen in Capone’s sister’s barn, that Grider said he used during the mail truck robbery, and that Gridеr later abandoned during another robbery. Other witnesses corroborated several other details of Grider’s story, but they could not name the persons involved or provide a detailed description of the events. Thus, only Grider’s testimony (while corroborated) absolutely identified the appellants as active participants in this particular robbery.
With this background in mind, we turn to the appellants’ claims.
1. Apрellants’ most significant argument arises out of the prosecutor’s remarks to the jury. In his rebuttal argument, the prosecutor made the following comments:
[Cjounsel [for defendants] suggest[] that when the government went out [to Grider’s prison to persuade him to testify], they sent their representatives, they’ve shaped the testimony of Mr. Grider as he testified.
.... They failed to point out to you that when they went out, Officer Owen, seated in the сourtroom was there. The same man that six years ago today lay on the ground wounded. He’s the man who went out there, and he talked to Grider, and they suggested his testimony had been shaped by the government.
A few minutes later, in closing his remarks, the prosecutor stated:
[T]he government would submit to you that it has proven its case beyond any reasonable doubt, all reasonable doubt, that six years ago today Officer Owеn la,, there in the street wounded, and he sits before you today awaiting the truth, awaiting your verdict.
Appellants’ counsel immediately moved for a mistrial on the grounds that these remarks were an inflammatory appeal to the jury’s passions.
Viereck v. United States,
We agree with the trial court that this last remark of the prosecutor was improper. We have held that prosecutors must avoid such comments given the “invisible cloak of credibility” that they wear “in virtue of their position,”
Patriarca v. United States,
The United States Attorney is the representative not of an ordinary pаrty to a controversy, but of a sovereignty whose obligation to govern impartially is as compelling as its obligation to govern at all; and whose interest, therefore, in a criminal prosecution is not that it shall win a case, but that justice shall be done. ... It is as much his duty to refrain from improper methods calculated to produce a conviction as it is to use every legitimate means to bring about a just one.
Berger v. United States,
The issue here, however, is whether it was necessary to retry the case or whether a cautionary instruction was adequate. To require a new trial, we must conclude either that, despite the instruction, the misconduct
*586
was likely to have affected the trial’s outcome,
compare United States v. Socony-Vacuum Oil Co.,
First, the prosecution’s appeal to passion, although improper, was isolated. The quoted remarks werе the only instances in the course of the five-day trial in which the prosecutor overstepped the bounds of proper conduct. They were not repeated after warnings by the judge, as in
Berger v. United States, supra.
And, they were “not cumulative evidence of a proceeding dominated by passion and prejudice. . .. ”
United States v. Socony-Vacuum Oil Co.,
[a] prosecutor [is] entitled to attempt to rehabilitate his witnesses, and when defense counsel makes inflammatory statements, we will allow the prosecutor somewhat greater leeway in rebuttal. See United States v. Medina,455 F.2d 209 , 210 (1st Cir. 1971) (criticism of Government witnesses may invite zealous rejoinder); cf. United States v. White,486 F.2d 204 , 206 (2d Cir. 1973), cert. denied,415 U.S. 980 ,94 S.Ct. 1569 ,39 L.Ed.2d 876 (1974) (dictum) (intemperate remarks at end of a long and hotly contested trial are harmless error.)
United States v. Flaherty,
Second, the improper appeal to passion seems to have been something less than deliberate. The remarks were not part of a prepared discourse,
compare United States v. Leon,
Third, the trial judge gave a strong, explicit cautionary instruction. He told the jury:
I am going to vary the usual order of instructions, because I do wish to deal with a matter raised in the last seconds of [the] rebuttal argument; that is, concerning Officer Owen, who is clearly from the testimony that we have a very brave and lucky officer, but his interest is not served and it is not your duty to serve his interest, if it were served, by anything other than a truthful verdict as you see it. The suggestion that one verdict as opposed to another is something that he is waiting for is something that you should disregard. I assume that neither he nor anyone else would want a verdict that reflected anything other than the truth as you see it given the burden of proof which the Constitution and lаws of the country put upon the government in criminal cases.
This explicit instruction, addressing the misguided implication directly and sharply, was, we believe, in light of the circumstances sufficient to counteract prejudice that flowed from the prosecutor’s statement.
United States v. Farnkoff,
Finally, it is most unlikely that any prejudice that survived the- jüdge’s instruction could have affected the outcome of this case. The evidence against the defendants was overwhelming if the jury believed Grider and worthless if it did not. Grider’s testimony was detailed and basically consistent. It was substantiated by significant independent corroboration. Flaws or inconsistencies in that testimony to which appellants point (e.g., whether Capone provided two or four guns and whether Capone wore a moustache in May 1975) were minor. The major reasons advanced for disbelieving Grider consisted of Capone’s denial of hic involvement (Murnane did not testify in his own behalf) and Grider’s status as a self-confessed accomplice granted immunity. These reasons were explored in detail and argued vigorously by counsel. Moreover, insofar as the jury was in doubt about Grider’s credibility making it more likely that the prejudicial remark affected its verdict, the tendency of the rational argument underlying the remаrk (as discussed above) to relieve that doubt makes the remark itself somewhat less prejudicial. In sum, the record reveals that the jury’s verdict could hardly have been the result of passion inspired by the brief remarks of the prosecutor but rather was based upon lengthy testimony, vigorous argument, and a reasonable belief that Grider was in fact credible. We therefore hold that the brief comments by the prosecutor, although improper, did not substantially prejudice the appellants and did not deprive them of their constitutional right to due process of law.
2. Appellants next complain that the district court did not adequately instruct the jury on the need to scrutinize Grider’s testimony with care. Appellants’ counsel requested, among others, the following instruction:
15. The jury is required to consider with great care and scrutiny the tеstimony of an unindicted co-conspirator to whom a reward or promise has been offered in return for his testimony.
In going over the proposed instructions with counsel, the court said, “15 is correct,” and later added, “I think I’m obliged to say extreme care, or particular care, or special care, and I’ll do that.” In due course, the trial judge gave two instructions on credibility. One was a general instruction, indicating that the jury should evaluate witness testimony according to their “common sense and knowledge of human behavior,” and the second referred specifically to Grider as an accomplice:
Mr. Grider is an accomplice; that is, by his own admission he participated in the crimes charged. And while the testimony of every witness is to be weighed with great care, the testimony of an accomplice must be considered with particular care.
*588 In considering whether to believe Mr. Grider, you may consider what interest he has in testifying, whether there was any particular reason that he should select these two defendants as the people who were with him on the hijack attempt.
Neither of appellants’ counsel objected to this instruction at the time; neither pointed out to the judge that he had nоt given the specific instruction in the precise words previously requested.
Appellants first argue that the judge violated Fed.R.Crim.P. 30 by failing to “inform counsel of its proposed action” on requested instruction 15. The short answer to this argument is that the judge agreed to give the instruction, he did in fact give a substantially similar instruction, and in any case .defendants were in no way prevented from making their argument to the jury.
See, e.g., United States v. Jones,
Appellants next object to the instruction actually given. Because the claimed error was not brought to the attention of the court it may only be attacked now if it was “plain error.” Fed.R.Crim.P. 52(b). Appellants claim that the court erred by departing from the words of the requested instruction; that by instructing the jury on a “particular care” standard rather than a “great care and scrutiny” standard, the court erred as a matter of lаw by reducing the degree of scrutiny required; ■ that the court narrowed the broad issue of Grider’s credibility to the narrow issue of his motive for singling out appellants; and by not mentioning the grant of immunity in the instruction, the court led the jury to discount defense arguments seeking to discredit Grider on that basis. Parsing of the language used and study of case law does not bear out these contentions.
See United States v. Hickey,
3. Appellants argue that the Government violated their constitutional rights by delaying their indictment for approximately two and one-half years.
United States v. Lovasco,
As the statute of limitations provides the main source of protection from delay in prosecution, it is necessary for appellant to prove
actual prejudice
in order to succeed on a claim that pre-indictment delay that yet resulted in an indictment within the statutory period resulted in a deprivation of due process.
Id.
at 789-90. This is a heavy burden.
See, e.g., United States v. Henry,
4. Appellants claim, and the Government concedes, that the names of the grand jurors who indicted them were not drawn “publicly” as required by the Jury Selection and Service Act of 1968, 28 U.S.C. § 1866(a), because there was no posted notice of the drawing. A violation of the Act, however, constitutes grounds for reversal only if it amounts to a “substantial failure” to comply with the statute. 28 U.S.C. § 1867(a). The failure to post notice is a “technical,” not a “substantial” violation. This matter was recently analyzed with care by the Fifth Circuit in
United States v. Bearden,
5. Capone claims that the trial judge should have instructed the jury on the question of his “withdrawal” from the conspiracy. Capone’s counsel never requested any such instruction, nor is there any record evidenсe which would, without highly imaginative argument, suggest a factual basis for that claim. There was thus no error in failing to deliver sua sponte a withdrawal instruction.
6. The remaining arguments we find frivolous. Murnane claims that the
*590
court improperly admitted evidence showing that he was engaged in a past crime. But a reading of the record makes it clear that the contested evidence showed that Murnane was
not
involved in the past crime. Capone argues that the verdicts against him were inconsistent. But, they are not necessarily inconsistent, and even if they were, inconsistent verdicts are lawful.
Dunn v. United States,
For these reasons the convictions are
Affirmed.
