OPINION OF THE COURT
William Edward Zeiler appeals his convictions for three bank robberies after a jury trial in the United States District Court for the Western District of Pennsylvania. Three eight-and-one-half year sentences, to be served concurrently, were imposed. On this, his third appeal to this court, Zeiler challenges the competency of witnesses who identified him at the time of the trial as the perpetrator of one of the robberies because of their exposure to: (a) extensive pretrial publicity identifying him as the robber, and (b) photographs of him, seen in the absence of defense counsel. We reject both of these contentions and affirm the convictions.
Zeiler was originally arrested in June 1967 as a suspect in a series of bank robberies. Following a hearing at which he unsuccessfully attempted to suppress identification testimony because of the pretrial publicity, United States v. Zeiler,
We considered appeals from both trials in United States v. Zeiler,
The claim that the Bloomfield witnesses were incompetent to testify because of unduly suggestive photograph displays deserves little comment. In Zeiler II, we considered the precise issue now appealed. At that time we found an independent origin for in-court identifications. We see no reason to reverse our holding now. The court was careful upon retrial to restrict witnesses to in-court identifications and to exclude testimony about photograph display identifications. Our instructions were followed explicitly. 1
Thus, the only real issue in this appeal is the nettlesome question of whether witnesses who have been exposed to extensive pretrial publicity identifying the defendant as the culprit should be disqualified from testifying as to the defendant’s identity. We did not meet this issue in either
Zeiler I,
The district court refused to suppress eyewitness identifications because of pretrial publicity both at a suppression hearing,
Confronted for the first time with the necessity of ruling on the pretrial publicity issue, we must review the facts. Following a five year series of bank robberies, Pittsburgh police mounted an extensive search for the “commuter bandit.” Sketches of the robber were widely circulated. When Zeiler was arrested and brought into the Federal Building on June 23, 1967, press and television photographers were on hand. Pictures were taken both in the basement parking area and on the thirteenth floor. Zeiler’s picture was shown on the three major television stations in Pittsburgh and appeared in both major newspapers. This publicity indicated that appellant was allegedly the elusive “commuter bandit.”
Appellant contends that the prosecuting authorities encouraged and assisted the news media. He notes that cameramen were waiting at the Federal Building when he arrived in official custody. He testified at trial that one of the offi *719 cials leading him into the Federal Building said to the photographers:
Hey, let’s give these other guys a chance here. Let’s slow up a little bit and let them get a good picture — give them a chance. . . . They have to make a living, too.
Three of the four witnesses to the Bloomfield robbery saw pictures of Zeiler’s arrest on television and in the newspapers; the fourth saw the arrest on television alone. All four witnesses testified at the suppression hearing that upon seeing Zeiler’s picture they knew this was the man they had seen robbing the Bloomfield bank. The four witnesses discussed the news reports among themselves prior to viewing Zeiler in a photograph display and at a line-up.
The competency of the eyewitness identifications is challenged on two grounds: (1) federal and local officials aided the news media in publicizing photographs of the arrest and (2) the media viewings made the witness identifications inherently suspect.
Appellant’s first ground can be easily dismissed. We need not decide whether encouragement, by law enforcement officers of prejudicial pretrial publicity should disqualify witnesses affected by such publicity, for the record does not support the defendant’s factual allegations. No evidence was presented that the pretrial publicity was controlled or directed by law enforcement authorities. Nor was there evidence that the arrest publicity was designed by them as a pre-line-up identification technique. Nothing in the record indicates that law enforcement authorities had set up a “meet the press” conference with Zei-ler. 2 The foregoing statement reputedly made by a Pittsburgh police official, even if true, is of little significance. The appellant has not shown that the publicity surrounding the arrest of the “commuter bandit” was anything more than normal news coverage, rather than the product of law enforcement officials trying to make a case in the newspapers or on television.
Appellant’s second ground is more troublesome. His claim combines elements of two separate lines of precedent, each concerned with protecting the integrity of the criminal proceeding as a fact finding mechanism. While conceding that no reported decision has ever declared eyewitness identifications incompetent because of pretrial publicity, defendant analogizes the effect of publicity on witnesses with its effect on jurors. He points to the Supreme Court’s conclusions that a fair trial can be denied because of the prejudicial psychological impact, either of pretrial publicity on jurors, Irvin v. Dowd,
Cases involving the psychological impact of pretrial publicity upon jurors, however, are not really apposite. The constitution guarantees an impartial jury. It does not guarantee an impartial witness. A juror must impartially analyze and weigh evidence presented at trial; he should not consider extra-judicial information about an alleged criminal act. A witness, on the other hand, is not charged with weighing the testimony and ascertaining guilt or innocence. He brings to the courtroom information related to the alleged crime. Of necessity, he lacks the detachment required of jurors.
Biased jurors can be weeded out on voir dire, or if necessary, by a change of venue. They can be replaced with neu *720 tral jurors. Witnesses are not so fungible. Disqualification of jurors because of exposure to pretrial publicity does not prevent trying a defendant; disqualification of witnesses may have that effect. We long ago abandoned the practice of disqualifying witnesses because of presumed bias. Bias can be examined through cross-examination, and juries are free to disregard biased testimony. The same standards cannot be applied to both jurors and witnesses vis-a-vis pretrial publicity.
The other line of precedents upon which appellant relies stems from cases such as United States v. Wade,
When, as in the present ease, there is no evidence that law enforcement officials encouraged or assisted in impermissive identification procedures, the proper means of testing eyewitness testimony is through cross-examination. 3 The credibility of witnesses’ subsequent identifications can be weighed by the jury in light of the witnesses’ statements as to their reactions to television or newspaper pictures. The danger that the jury may give undue weight to eyewitnesses’ testimony can be further guarded against by appropriate jury instructions. 4
The judgment of the district court will be affirmed.
Notes
. The distinction between in-eourt identifications and at-trial testimony about prior photograph identifications was necessary because of our holding in Zeiler I,
. In fact, Federal Department of Justice regulations discourage pretrial pictures of suspects. It is Department policy that its personnel:
should take no action to encourage or assist news media in photographing or televising a defendant or accused person being held or transported in federal custody.
. In tlie present ease, no reference by either party to the witnesses’ media viewings was made at trial, either on direct or cross-examination. The trial judge would not permit the Government to introduce evidence about the photograph or line-up identifications. Counsel for the defendant was not prevented from cross-examining the witnesses about the lineup, the photograph display or the media viewings. Had defense counsel wished to attack the credibility of the in-court identifications on the basis of these previous identifications, he could have done so.
. In United States v. Barber,
In any case raising the question whether the defendant was in fact the criminal actor, the jury will be instructed to resolve any conflict or uncertainty on the issue of identification. The jury will be instructed that identification may be made through the perception of any of the witness’ senses, and that it is not essential that the witness himself be free from doubt as to the correctness of his opinion. The identification testimony may be treated by the jury as a statement of fact by the witness: (1) if the witness had the opportunity to observe the accused; (2) if the witness is positive in his identification; (3) if the witness’ identification testimony is not weakened by prior failure to identify or by prior inconsistent identification; and (4) if, after cross-examination, his testimony remains positive and unqualified. In the absence of any one of these four conditions, however, the jury will be admonished by the court that the witness’ testimony as to identity must be received with caution and scrutinized with care. The burden of proof on the prosecution extends to every element of the crime charged, including the burden of proving beyond a reasonable doubt the identity of the defendant as the perpetrator of the crime for which he stands charged.
