Willie Barnett was convicted after trial by jury of assault with intent to rob while armed with a dangerous weapon (G. L. c. 265, § 18) and of three counts of *88 assault and battery by means of a dangerous weapon (G. L. c. 265, § 15A). He was sentenced to concurrent terms of five to seven years, to be served at the Massachusetts Correctional Institution at Walpole, from and after a sentence remaining to be served in the State of Alabama. An appeal under G. L. c. 278, §§ 33A-33G, is here, having been transferred from the Appeals Court under G. L. c. 211A, § 10 (A).
The jury may be taken to have viewed the facts thus. On September 3, 1971, the defendant and two accomplices (both initially assumed by witnesses to be men) entered the Buy Rite Store, a grocery at 1627 Washington Street in the South End of Boston, with intent to rob it. As the defendant came through the front door and drew a shotgun from a paper bag, Clinton Tennyson, a uniformed security guard standing about ten feet away, saw the defendant and the gun although there were several customers in the intervening space. Tennyson ran down an aisle toward the rear of the store. The defendant shot and wounded the store manager, Byron Randall, who was standing behind a cash register, and then ran out the door, apparently without getting at the money. Meanwhile Tennyson moved down the other aisle toward the front of the store while drawing his .38 caliber revolver from his holster. The defendant came back through the door. The two exchanged shots. Tennyson and Mrs. Elizabeth Ware, a customer, were wounded by the shotgun blast (Tennyson receiving shot in his abdomen, face, and right arm), but, as later appeared, neither was seriously injured. The robbers fled.
Police arrived promptly and took Tennyson, Randall, and Mrs. Ware to Boston City Hospital. As one of the police units that had transported the wounded was returning to its station, the officers observed the defendant and another seated on the fender of a car in the parking area of a nearby garage at Shawmut Avenue and Ruggles Street. These two matched the rather general descriptions of two of the robbers that the officers had obtained at the scene and evidently over the police radio; and (according to testimony received at voir dire but not at trial) adjacent to the two was a red Ford Falcon automobile with *89 a Connecticut license plate No. JS2939 matching a description, received over the radio, of a red automobile with Connecticut license plates believed to have been the car in which the robbers made their escape down Shawmut Avenue after the robbery attempt. Stopping at the garage, the officers saw that the defendant was bleeding from a gunshot wound in his left shoulder. As it turned out, the other person was a woman with close-cropped hair dressed in man’s clothing. The officers took the two to Boston City Hospital. The defendant was hysterical and nauseated during the short drive.
As the defendant lay on a litter in an X-ray room with gauze visible covering his wound, Tennyson was wheeled into the room, also on a litter, and he immediately and positively identified the defendant as the man who had shot him. 1 The confrontation occurred within an hour of the robbery. At the trial Tennyson also identified the defendant as the gunman.
When the doctors later extracted the slug lodged in the defendant’s shoulder, it proved to be of .22 caliber and not capable of being fired from Tennyson’s revolver. There was no testimony of any gunplay at the store besides that between Tennyson and the defendant, but a discharge from a .22 caliber weapon was not excluded. 2
*90 The strength of Tennyson’s identification was enhanced by his testimony that he had seen the defendant at the store three or four times in the month preceding the robbery; he had particular reason to recognize him during the robbery because on a visit to the store earlier that week the defendant had called him “Uncle Tom’s old nigger.” 3 On the other hand, the probative force of the fact that the slug in the defendant’s shoulder could not have come from Tennyson’s revolver was no doubt minimized by the jury because the defendant wavered badly on how the wound came to be inflicted. When the officers spoke to the defendant at the garage and subsequently at the hospital, he claimed he was robbed of $75 at a fruit stand across the street from the garage and had been shot during a struggle with the robbers. Early the next day he told the police that he shot himself accidentally during an argument and scuffle with his wife. At trial his story mediated between the two versions. He said he left the garage in midafternoon and was robbed (but not shot) at the fruit stand; he did not return to his companions at the garage but continued to his sister’s apartment several blocks away where he was living with his wife; disgusted at the loss of his money, he attempted suicide with his sister’s revolver, but succeeded only in wounding himself in the shoulder; he then returned to the garage on foot and was apprehended by the police. 4
*91 On this appeal, the defendant argues that the judge committed error in declining on the defendant’s motion (1) to suppress the out-of-court and in-court identifications by Tennyson; (2) to allow the defendant to examine testimony before the grand jury; (3) to permit the defendant to make certain offers of proof; (4) to grant a mistrial. Error is also claimed (5) in the judge’s failure to halt the prosecution’s pursuing a certain line of cross-examination.
1. The defendant moved in advance of trial to suppress evidence of identifications of him, both in- and out-of-court, by the eyewitness Tennyson. 5 Following the method and standards derived from the Wade-Gilbert-Stovall cases, 6 the judge received evidence at an extended voir dire regarding the circumstances of the hospital identification which paralleled the evidence on the subject at trial summarized above. The judge found the confrontation at the hospital to be permissible; accordingly he ruled that the testimony as to that identification could be admitted at trial, and as there was “no poison” in the hospital confrontation, there was no need to show that an in-court identification would be based on an independent untainted source. Paying due regard to the judge’s appraisal of the testimony, we find no basis for rejecting his conclusion.
A “one-on-one” confrontation with a person in custody
*92
is disfavored generally as a basis of identification (see
Stovall
v.
Denno,
The judge could properly hold here that there were no such “special elements of unfairness”
(Russell
v.
United States, supra
at 1284) as might take the case out of the general class permitting a confrontation without lineup. He found, to the contrary, “no indication of any police desire or intention to deal with Barnett unfairly.”
7
He also found the police could think the defendant seriously wounded. See
People
v.
Smith,
We should add that the judge’s ruling was not the end of the matter. It meant only that the testimony could be presented to the jury for assessment by them. Tennyson and the others who testified to the identification were subjected to full and vigorous cross-examination by the defendant, and much of the defendant’s closing argument was focussed on persuading the jury that the setting of the identification was conducive to mistakes and that the identification was in fact erroneous. See Russell v. United States, supra at 1285.
2. Although a possible inconsistency had appeared in Tennyson’s testimony about the exchange with the defendant on his previous visit at the store (see n.3), the judge refused the defendant’s motion to be allowed to examine Tennyson’s testimony before the grand jury; the judge referred to the fact that the defendant had access to Tennyson’s testimony at the probable cause hearing. This was before a new, prospective rule regarding inspection of grand jury minutes was announced in
Commonwealth
v.
Stewart,
3. At trial, during cross-examination of one of the officers who had observed the hospital confrontation, the defendant asked whether the officer thought Tennyson’s condition was serious. The judge excluded the questions and then refused to permit the defendant to make an offer of proof, which would have been (as the defendant says in his brief) that the officer did not think Tennyson was *95 badly hurt — attempting thus to attack the propriety of the showup. The defendant claims that the refusal of the offer was error. Strangely, he does not assert that the judge erred in barring the questions. The claimed error may be thereby precluded, but we think it is anyway unsubstantial.
Ordinarily a defendant is not required to make an offer of proof in order to preserve for appeal a ruling excluding a question on cross-examination (see
Civitarese
v.
Gorney,
*96
4. A police officer present at the hospital stated in response to a question by the prosecutor that Barnett “was identified [at the hospital] by the victims as being one of the three men involved in the attempted hold-up and shooting____” The defendant’s counsel approached the bench and asked that the answer be struck and moved for a mistrial for prejudice; no hospital identification other than Tennyson’s was to be offered at the trial. (See n.2.) The judge denied the mistrial but granted the motion to strike, saying, “The answer was not strictly responsive to the question. It is stricken; and the jury will disregard it.”
10
Whether to grant a mistrial is largely a discretionary matter. See
Murray
v.
Foster,
5. The prosecutor in cross-examining the defendant about his explanation of the shoulder wound put questions as to whether he had told a police officer that he had lost his money in a crap game and as to whether he had had an argument with his wife. The defendant now contends that the convictions should be reversed because the questions were argumentative and suggestive. The contention is not available because the defendant did not object when the questions were first asked and answered. But the ques-. tions sought further to impeach the much impeached defendant’s testimony, and there is no intimation that the prosecutor was implying the truth of any proposition that he knew to be false, or was otherwise trying to inflame the jury. Cf.
Commonwealth
v.
Redmond,
Judgments affirmed.
Notes
In an affidavit filed in support of a motion to inspect grand jury minutes, the defendant indicated that Byron Randall had also identified him at the hospital as the gunman. The Commonwealth stated during voir dire that Randall could not be located and would not appear as a witness for the prosecution.
Tennyson said that he and the defendant exchanged simultaneous shots. Yet Mrs. Ware testified that after she heard a loud noise at the front of the store (presumably the shooting of Randall), Tennyson ran past her and she then heard “bang-bang” — distinct shots. It is possible that the second bang was the firing of a .22 caliber weapon. Or perhaps the witnesses at the store did not hear the report of a .22 caliber weapon in the confusion and in comparison with the louder discharge of the shotgun and the .38.
As the defendant drew the shotgun from the paper bag, one of his companions was near Tennyson and the other was standing by the cash register. The record does not make clear how the two escaped from the store.
At the probable cause hearing Tennyson said a fellow with the defendant at the previous visit called him “Honky Tonk.” This left the possibility that Tennyson, who was a somewhat inarticulate witness, meant that the defendant called him “Uncle Tom’s old nigger” and the companion called him “Honky Tonk,” but on voir dire and at trial Tennyson appeared to deny that the companion made the statement.
The defendant testified that he was employed at the garage but was not working on the day of the robbery. His story at trial was partially, but lamely, confirmed by a mechanic at the garage who testified for the defense. Both asserted that the police arrived and apprehended the defendant some time before 4 P.M., which was before the robbery occurred. There were certain mutual inconsistencies in their accounts of why the defendant was waiting at the garage instead of going to the hospital for treatment of his wound.
This motion was made originally on the theory that the identification at the hospital should be suppressed because of the absence of counsel. After the filing of the motion the Supreme Court held in
Kirby
v.
Illinois,
United States
v.
Wade,
It may be observed that if the confrontation had occurred by accident, rather than through honest police procedure, but in equally suggestive circumstances, there would be no question about the admission of the identification. See
Commonwealth
v.
Leaster,
In Stovall the defendant was handcuffed to a police officer and was the only Negro in the room when the eyewitness identified him in response to an officer’s question whether the defendant “was the man.”
Indeed, where the record did not disclose the reason why the cross-examiner sought an answer to an excluded question, we have held on occasion that an exception might be inadequate in itself to preserve the issue for appeal. See
Breault
v.
Ford Motor Co.,
The case of
McGeorge
v.
Grand Realty Trust, Inc.,
The judge could have reasoned that a statement to the jury in that form would be better than one that directed specific attention to the content of the answer.
