The defendant was convicted of manslaughter on an indictment charging him with the first degree murder of Robert Sultis. He appeals and assigns two errors in his trial. G. L. c. 278, §§ 33A-33G. He argues that the Commonwealth withheld from him exculpatory evidence which was material to his defense and that the prosecutor made an improper reference in his summation to the defendant’s failure to call a particular witness. We affirm the judgment.
We summarize briefly the evidence presented at the trial. In the early morning hours of January 13, 1978, Robert Sul-tis and his friend Hawkins were at the Fan Club, a lounge on Warrenton Street in Roston. They had gone there together but separated upon their arrival to mix and socialize with other patrons. Sultis was at the bar, and two or three other patrons observed him reach over the bar and into the open drawer of the cash register, take some money from it, and leave quickly. They alerted the bartender to what they had just seen, and he called out to other employees telling them to stop the man leaving. The defendant, a doorman at the club, along with one or two other employees, gave chase to Sultis. They apprehended him a short distance up the street from the club, and they milled about him demanding he return to the club with them “to straighten the matter out.” They were seen by Hawkins, who had left the club and was farther down the street in his car ready to drive away from the area. He rapidly backed his car up the street towards the group, swerving and causing the members to scatter slightly. When he stopped the car, Sultis came around to the front passenger side and slowly got into the car. The defendant followed him while the others stood to the rear of the car. The defendant then ap *653 peared partially in the car struggling with Sultis, whom he was trying to pull out of the car. Hawkins got out of the car and approached the men standing behind it, and Sultis slid over to the driver’s seat. At this moment a police car containing three officers and a civilian drove by. Two of the three officers testified to their respective observations of the events which next occurred in quick succession: the defendant stepped back from the car with a gun in his hand; he fired a shot into the front seat area; and the car suddenly sped off and came to a crashing stop about a half block away. The defendant was arrested almost immediately for the shooting which caused Sultis’ death. It was the Commonwealth’s case that the defendant, using either his own gun or one taken from Sultis, deliberately shot him.
The defendant maintained that the shooting was an accident. He testified that as he was struggling with Sultis in the front seat of the car, Sultis produced a gun which accidentally discharged as a result of either the struggle or the sudden acceleration of the car. A knapsack containing a pellet gun was later found by the police under the front seat of the car. It is this gun, which was not the instrumentality of the crime, which gives rise to the defendant’s first claim of error at his trial.
Hawkins testified at the probable cause hearing that the pellet gun was not his, that he did not know to whom it belonged, and that he had not known it was even in the car. (The car belonged to Hawkins’ mother.) At the trial Hawkins did not deny that the pellet gun was his, and he admitted that he had testified to the contrary at the probable cause hearing.

His acknowledgement of his prior inconsistent statements prompted defense counsel to move to dismiss the indictment on two grounds. The first basis for the motion was the defendant’s allegation that the Commonwealth had knowingly allowed Hawkins to testify falsely at the probable cause hearing. The judge found that neither the issue
*654
of Hawkins’ credibility nor the question of ownership of the pellet gun was crucial or material to the determination of probable cause, especially in view of the fact that two of the three police officers who had observed the shooting also testified at the hearing. See

v.
Pugh,
We relate the facts testified to at the evidentiary hearing on this motion as the judge found them because our review of the transcript reveals that his findings are well warranted on the evidence elicited at the hearing. See
Commonwealth
v.
Accaputo,
In preparing for trial, the prosecutor asked the polygraph examiner for a written report of his session with Hawkins. The prosecutor received this report on June 8, 1978, and he, in turn, gave it to defense counsel on June 12,1978. The report contained the statement that Hawkins told the examiner during the pre-test interview that the pellet gun was his. O’Meara testified during the trial that he knew of Hawkins’ admission to the examiner as of the date of the examination, January 24; however, at the evidentiary hearing O’Meara stated he did not learn of Hawkins’ admission any earlier than June 12. When questioned about his contradictory testimony, O’Meara replied that he had been confused as to dates when he had given his trial testimony but that he was now certain it was no earlier than June 12. The polygraph examiner also testified at the motion hearing that on January 24, 1978, he advised O’Meara of the substance of Hawkins’ examination but that he did not tell O’Meara of *656 Hawkins’ statement concerning his ownership of the pellet gun. It was also discovered during the evidentiary hearing that on the morning of June 12 Hawkins had told the prosecutor and O’Meara that he had lied about the ownership of the pellet gun at the probable cause hearing. No one advised defense counsel of this conversation.
The judge “specifically” found that O’Meara did not know of Hawkins’ prior admission of ownership of the pellet gun when he testified to the contrary at the probable cause hearing. Although Hawkins had told O’Meara that he referred to Sultis as “cousin” and had told O’Meara on January 24 that the gun “might have been” his cousin’s, there was no testimony to this effect at the probable cause hearing other than Hawkins’ previously described response which was cut short by an objection. 4 The judge found that Hawkins’ admission to the prosecutor and O’Meara on the morning of June 12, which was not related to defense counsel, was “cumulative impeachment ammunition” at best. He concluded that there was no evidence to support a finding that the Commonwealth had deliberately suppressed exculpatory evidence. We agree. 5
The defendant points to his general demands to the Commonwealth that he be furnished with exculpatory evidence, and seeks to invoke the holdings of
Brady
v.
Maryland,
The defendant next points to the prosecutor’s failure to advise him on June 12, 1978, that Hawkins had just informed him (the prosecutor) and O’Meara that he had lied at the probable cause hearing. He argues that this “omission must be evaluated in the context of the entire record.”
Commonwealth
v.
Ellison,
The defendant’s second and final assignment of error concerns the prosecutor’s closing argument wherein he made reference, over the defendant’s objection, to the defendant’s failure to call a particular witness, Detective Ryan. He was one of the three officers who happened upon the scene at the precise moment of the shooting. He was seated in the front seat of the police cruiser. In his opening remarks to the jury, the prosecutor referred to him as an anticipated witness; however, Detective Ryan was never called to testify at the trial. Defense counsel argued to the jury in his summation that Ryan had the best opportunity of all the occupants of the police cruiser to observe the shooting. He told them that “you have a right to expect the Commonwealth to produce all the evidence in the case, and particularly that which is from the best vantage point.” The prosecutor met these remarks head-on in his summation: “If Detective Ryan was so important to [the defendant’s] case, isn’t it true that he could have put him on himself? ... If [the defendant] hadn’t made the movements that he did with that witness, did he show the witness was unavailable in his own case?”
The defendant argues that he was entitled with impunity to invite the jury to draw an inference adverse to the Commonwealth because the witness was a police officer. He contends that, as such, the witness was not equally available to him and that the witness was favorably disposed to the Commonwealth. “Whether an inference can be drawn from the failure to call witnesses necessarily depends, as with inferences generally, upon the posture of the particular case and the state of the evidence.”

O’Rourke,
We will not establish an ironclad rule that police officers are “clearly favorably disposed” witnesses to the Commonwealth and unavailable to defendants. See
Commonwealth
v.
Morrissey,
Judgment affirmed.
Notes
This admission came after persistent and exhaustive cross-examination during which Hawkins stated, “I lied, I lied.”
A prosecutor’s failure to disclose exculpatory evidence pursuant to defendant’s request is not a ground for dismissing an indictment. While the defendant’s motion was mislabelled, as it related to this allegation, the judge nonetheless considered it as if it were a motion for a mistrial or a motion for a new trial.
Hawkins and Sultis were not related, but they had been friends for many years and referred to each other in this manner.
O’Meara testified that he thought Hawkins called Sultis “brother,” although he did acknowledge that he “might have” known of the “cousin” reference.
In light of this finding it is unnecessary to consider the defendant’s contention that a deliberate suppression requires a dismissal of the indictment.
“If there is no reasonable doubt about guilt whether or not the additional evidence is considered, there is no justification for a new trial. On the other hand, if the verdict is already of questionable validity, additional evidence of relatively minor importance might be sufficient to create a reasonable doubt.”
