RAPER, Chief Justice.
The defendant-appellant was charged with aggravated robbery in violation of § 6-66, W.S. 1957,1 (§ 6-4-402, W.S. 1977), found guilty by a jury and sentenced to a penitentiary term of not less than eight nor more than fifteen years. On appeal, defendant defines the issues to be:
“1. Whether the Trial Court’s refusal to suppress the in-court identification of the Defendant as the perpetrator of the robbery by the victim deprived the Appellant of due process of law.
“2. Whether the Trial Court committed plain error in refusing to instruct the jury as to its consideration of identification testimony.”
We will affirm.
Early in the morning hours, Woody’s Truck Stop was robbed. The testimony was that after the robber had left Woody’s Truck Stop, the victim-attendant, Hughes, got on the company C.B. and called for help. The call was received at the police station and an alert went out to patrolling officers. Officer Brent drove to Woody’s Truck Stop where the attendant pointed in the direction of 5ch and Morrie. According to Brent, he took off immediately without stopping to interview the attendant.2 On the way to 5th and Morrie, not far away, he broadcasted by radio his destination to two other patrol cars, both of which converged on the vicinity. Officer Brent testified that while he was approaching the area, two or three blocks away, he saw a vehicle leave the curb at high speed, so took off in pursuit. Though there is no testimony that any witness saw the defendant exit the vehicle, the circumstances indicate that he did so because Officer Markland spotted him in flight in the area, chased after and apprehended him.
In the meantime, Officer Kolkman came up to assist. Officer Brent then went back to talk to the attendant where he was interviewed. Brent took into evidence a white paper sack. Other officers appeared to make a crime scene investigation. Brent took Hughes to the police station to take a statement.
Markland, the officer while engaged in the chase, saw the defendant take off a green jacket and throw it on the ground. He assisted in the search of the defendant for weapons. He identified the defendant [361]*361in the courtroom as the person apprehended and, during the course of that identification, noted that the defendant, at the time of trial, was attired in a wine colored leisure suit and had a mustache. He recovered the green jacket and searched the vehicle. He observed a quantity of paper currency blowing around in the wind and a black wig laying on the ground. In the vehicle, on the seat, was a pistol along with more loose currency. The total amount of currency recovered was $403.00. Later on, an additional $30.00 was taken from the defendant’s person.
Kolkman, one of the three pursuing officers, identified defendant as wearing a T-shirt, dark pants, medium length hair and having a mustache at the time of apprehension. His testimony was that the defendant was apprehended about three blocks north of Woody’s. He testified that the money blowing around was picked up. He also testified that he saw a black and gray checkered hat on the floor of the vehicle and the wig. A fourth officer investigated the crime scene, Woody’s Truck Stop, where he found a bullet hole in a wooden counter shelf and assisted in prying out the bullet.
A fifth officer testified that he picked up a .22 caliber short cartridge case from the floor of the truck stop. The State’s chief forensic scientist and director of the crime laboratory positively identified the cartridge case by use of a comparison scope, matching its firing pin marks with those on the eases of cartridges test-fired from the pistol recovered by Officer Markland from the vehicle. He could not identify the bullet other than saying that it was also .22 caliber, but pointed out it was too badly battered to identify as being a bullet fired from the recovered firearm.
The filling station attendant, Hughes, was the last witness to testify for the State. In the courtroom he identified the defendant as being the one who had held him up at Woody’s Truck Stop by pointing a pistol in his face. He particularly recalled what the defendant was wearing. He testified further that the robber was carrying a white paper bag and directed Hughes to hand over all of the money from the cash register — a quantity of paper currency— which Hughes did, after which the defendant told Hughes to lay on the floor. After the robbery, he made an “inventory” and found there to be $403.00 missing. He testified that, before departing, the robber shot off the pistol a foot or so over the top of his head and took off. After lying there for a few minutes, he got on the company’s C.B. and called for help. Hughes testified that, at the time of the robbery, the defendant had a mustache was wearing a green coat, had long stringy hair (the wig) and was wearing a dark hat. When handed the green jacket in the courtroom, he recalled the dark spot on the shoulder. The defendant was asked to stand. Hughes said the robber was the same height and weight.
At the preliminary hearing, in the presence of Hughes, the defendant was escorted into the courtroom of the Justice of the Peace in jail clothing and handcuffed. Defendant objected to his attire. The interrogation of Hughes by the county attorney got hardly past its introductory stage. He had described his duties at Woody’s Truck Stop as night attendant. A few minutes before 2:00 a. m., a “guy” came through the door, raised up a gun, put a sack on the counter and said “hand it over”. He was wearing dark colored headgear, like a skullcap, had long-black-stringy hair, was wearing a rain jacket, had dark pants and had a mustache. He was asked if he “might” recognize the person if he saw him again. Hughes answered “yes”. Counsel then queried: “Mr. Hughes, from your independent recollection and trying to recall what happened that evening, would you say the Defendant was that person? After some interchange between counsel and further questions, Hughes answered “yes, he’s in the room; he’s sitting by his attorney.” That is as far as the preliminary progressed when it was aborted by the Justice of the Peace. At that point, the presiding Justice of the Peace became indignant over defendant’s manner of dress for the occasion, suspended the hearing as a “farce” and disqualified himself from participation in any further preliminary procedures. The pre[362]*362liminary hearing was later reconvened before another Justice of the Peace, at which the defendant was bound over to the district court. No transcript of testimony received at the last preliminary hearing appears in the record.
Before commencement of trial, the defendant moved to suppress any in-court identification of defendant by Hughes on the ground that the circumstances of defendant’s appearance at the first preliminary hearing so tainted identification by Hughes that defendant was denied due process. The trial judge denied the motion. The defendant relies strongly on statements made in Frasier v. State, 1974, 262 Ind. 59, 312 N.E.2d 77, cert. den. 419 U.S. 1092, 95 S.Ct. 686, 42 L.Ed.2d 686, and Estelle v. Williams, 1976, 425 U.S. 501, 96 S.Ct. 1691, 48 L.Ed.2d 126. We have no disagreement with either case.
In Frasier the court relied upon Stovall v. Denno, 1967, 388 U.S. 293, 87 S.Ct. 1967, 18 L.Ed.2d 1199, which recognized a rule already in existence that the inquiry is “whether * * * the confrontation * * was so unnecessarily suggestive and conducive to irreparable mistaken identification that he [the defendant] was denied of due process of law.” 388 U.S. at 301-302, 87 S.Ct. at 1972,18 L.Ed.2d at 1206. (Bracketed material supplied.)3 The Frasier court concluded the test to be whether the witness was, in fact, influenced by the totality of the circumstances in a manner indicating a very substantial likelihood of misidentifi-cation. The case held on the facts before it there to be no substantial likelihood of mis-identification. We agree with the “totality” test and find it applicable but not with the same result urged by defendant.
Estelle deals only with the problem of the appearance of a defendant in prison garb at a jury trial and not with his appearance at a preliminary hearing. Nor does Estelle hold that it is inherently error for a defendant to wear prison garb during trial. The case does not concern identification and holds only that, in the absence of objection, the fact that defendant appeared in identifiable prison clothing was not error. We do not disagree with the principles of Estelle but find them inapplicable to the case before us, in that we are concerned with a preliminary hearing and an identification issue.
Following the Gilbert-Wade-Stovall triad in Simmons v. United States, 1968, 390 U.S. 377, 88 S.Ct. 967, 19 L.Ed.2d 1247; Foster v. California, 1969, 394 U.S. 440, 89 S.Ct. 1127, 22 L.Ed.2d 402; Coleman v. Alabama, 1970, 399 U.S. 1, 90 S.Ct. 1999, 26 L.Ed.2d 387; Neil v. Biggers, 1972, 409 U.S. 188, 93 S.Ct. 375, 34 L.Ed.2d 401; and Manson v. Brathwaite, 1977, 432 U.S. 98, 97 S.Ct. 2243, 53 L.Ed.2d 140, in that order, the Supreme Court has struggled with the scope of due process protection against the admission of evidence derived from suggestive identification procedures.
In this court, the issue of unnecessarily suggestive pretrial identification has not been met head on. The matter has only been touched at its fringes. While not clearly delineated, this court in Fresquez v. State, Wyo.1971, 492 P.2d 197, indicates its acceptance of the rule that the court will look at the totality of the circumstances surrounding a pretrial confrontation that is suggestive or conducive to mistaken identification. The Court had before it Simmons v. United States, supra and Stovall v. Den-[363]*363no, supra. It did not, however, consider an accidental meeting between a rape victim and the defendant-assailant at the police station, in looking at the totality of the circumstances, as a suggestive confrontation conducive to mistaken identification, particularly since that objection was not raised at the trial.
There are not many cases involving preliminary hearing, pretrial identification. In State v. Strickland, 1976, 113 Ariz. 445, 556 P.2d 320, the defendant was first identified by the victim of a robbery at a preliminary hearing after having failed twice to identify him at two “live” lineups or at a photo lineup, and had, in fact, singled out another individual altogether at a live lineup. Her (the victim’s) opportunity to see the defendant was before the incident when, with two others, he walked past while she had no interest in observing the individual characteristics of each. She was grabbed from behind and a money pouch taken from her. In the struggle, she lost her glasses and could not see the attacker afterwards. At the preliminary hearing, the defendant wore a county jail T-shirt and was seated alone with counsel at the defense table. She then found she could identify the defendant with certainty. She had been informed that the defendant had confessed. In the Strickland case, the Arizona Supreme Court found there was “very substantial likelihood of irreparable misidenti-fication,” citing Simmons v. United States, supra at 384, 88 S.Ct. at 971, 19 L.Ed.2d at 1247, and reversed the conviction even though defendant had confessed to the crime. The court went on to hold that it could not say that the witness’ “positive identification was harmless and did not contribute to the verdict.” At the same time, the court did not proscribe identification made for the first time at preliminary hearings and emphasized that the suggestibility of preliminary hearings does not per se taint the subsequent in-court identification, citing State v. Williams, 1976, 113 Ariz. 14, 545 P.2d 938, where the pretrial identification was of a man manacled to a police officer (not at a preliminary hearing). We conclude that case to be one which must be isolated on its unique facts. Its principal value is a demonstration of the extreme circumstances that must exist to suppress identification testimony at a preliminary hearing.
On the other hand, in the bank robbery case of United States v. Black, 6th Cir. 1969, 412 F.2d 687, F.B.I. agents took two witnesses from Tennessee to a Chicago courtroom during the hearing of a pretrial motion at which the defendant, not in prison garb, was present. At the request of the district attorney yet another witness was taken to observe a pretrial motion hearing at which the defendant was again present. The court held there was no violation of due process and acknowledged that whether due process had been violated depended upon the totality of the circumstances, citing Simmons v. United States, supra. See also to the same effect, United States v. Lipowitz, 3rd Cir. 1968, 401 F.2d 591, where witnesses were requested to sit in the courtroom during arraignment. There was held to be no due process violation.
In United States ex rel. Springle v. Follette, 2nd Cir. 1970, 435 F.2d 1380, cert. den. sub nom. Springle v. Zelker, 401 U.S. 980, 91 S.Ct. 1214, 28 L.Ed.2d 331, it was said that a totality of circumstances necessarily means that the entire trial must be scrutinized to see whether on balance the petitioner received a fair hearing. Clemons v. United States, 1968, 133 U.S.App.D.C. 27, 408 F.2d 1230, cert. den. 394 U.S. 964, 89 S.Ct. 1318, 22 L.Ed.2d 567, involved a preliminary hearing identification by witnesses but not under the circumstances before us (no jail garb or handcuffs). The concurring opinion of Circuit Judge Leventhal expressed the view that the Court must assess not only the totality of circumstances surrounding a particular identification but also the totality of trial proof bearing on the likelihood of misidentification. The approach would in effect create an overlap with the harmless error rule. The Supreme Court in Wade, supra (footnote 3), 388 U.S. at 242, 87 S.Ct. at 1940, remanded for a determination of “whether the in-court identifications had an independent source, or whether, in any [364]*364event, the introduction of the evidence was harmless error * * *.”
The federal cases cited in the preceding two paragraphs, as do many other cases, West’s Digest System, place some significance on whether the questioned pretrial identification took place before or after Stovall v. Denno, supra, even though it was specifically stated in „Stovall that a claim of unnecessarily suggestive identification conducive to irreparable mistaken identification was an already recognized rule. (See our footnote 3). In Manson v. Brathwaite, supra, as we view it, an effort was made to clear up various misconceptions and questions that had arisen from Stovall, supra; Neil v. Biggers, supra; Simmons v. United States, supra; Foster v. California, supra; and Coleman v. Alabama, supra, with respect to the relationship between suggestiveness and misidentification. The Court in Manson said:
“We therefore conclude that reliability is the linchpin in determining the admissibility of identification testimony for both pre- and [post]-£>tova// confrontations. * * *” 432 U.S. at 114, 97 S.Ct. at 2253, 53 L.Ed.2d at 154.
While it is difficult to do so, we conclude that the Manson Court separates the reliability of the identification from other evidence of guilt. Justice Blackmun in the Court’s opinion:
“Although it plays no part in our analysis, all this assurance as to the reliability of the identification is hardly undermined by the facts that respondent was arrested in the very apartment where the sale had taken place, and that he acknowledged his frequent visits to that apartment.” (Footnote omitted.)
Then Justice Stevens in his concurring opinion:
“Second, in evaluating the admissibility of particular identification testimony it is sometimes difficult to put other evidence of guilt entirely to one side.* Mr. Justice BLACKMUN’S opinion for the Court carefully avoids this pitfall and correctly relies only on appropriate indicia of the reliability of the identification itself. * * *”4 432 U.S. at 118, 97 S.Ct. 2254-55, 53 L.Ed.2d at 156.
We therefore divide a consideration of the problem into two phases: First, the court must consider whether upon a totality of the circumstances, there is a very substantial likelihood of irreparable misidenti-fication, and, if so, to secondly consider harmless error. In the first phase, Manson discards a per se approach which focuses on procedures and requires exclusion of out-of-court identification whenever obtained through unnecessarily suggestive confrontation procedures without regard to reliability. The defendant in the case now before us urges this course. The Manson -approved approach relies upon the totality of circumstances but permits the admission of pretrial identification evidence, if despite the suggestive aspect, it possesses features of reliability. It is an ad hoc course which permits relevant evidence for consideration and evaluation by the fact trier, the underlying factor being that of fairness. Justice Blackmun, writing for the Court, spoke approvingly of language used by Judge Lev-enthal in his concurring opinion in Clemons v. United States, supra:
“ ‘It is part of our adversary system that we accept at trial much evidence that has strong elements of untrustwor-thiness — an obvious example being the testimony of witnesses with a bias. While identification testimony is significant evidence, such testimony is still only evidence, and, unlike the presence of counsel, is not a factor that goes to the very heart — the “integrity” — of the adversary process.
“ ‘Counsel can both cross-examine the identification witnesses and argue in [365]*365summation as to factors causing doubts as to the accuracy of the identification— including reference to both any suggestibility in the identification procedure and any countervailing testimony such as alibi.’ ” Fn. 14, 432 U.S. 113, 97 S.Ct. 2252-53, 53 L.Ed.2d 153.
The Manson Court would then, against a test of reliability, employ the factors to be considered, set out in Neil v. Biggers, supra. As expressed in Manson :
“ * * * These include the opportunity of the witness to view the criminal at the time of the crime, the witness’ degree of attention, the accuracy of his prior description of the criminal, the level of certainty demonstrated at the confrontation, and the time between the crime and the confrontation. Against these factors is to be weighed the corrupting effect of the suggestive identification itself.” 432 U.S. at 114, 97 S.Ct. at 2253, 53 L.Ed.2d at 154.
We use the Manson version because of the last sentence which did not appear in Neil v. Biggers, supra, because it gives us a guide to what to do with the factors after-we ferret them out.
Applying those factors, then, we see that Hughes had an adequate opportunity to view the defendant, perhaps a minute and a half or so. He was no casual observer but the victim of the unforgettable and dangerous experience of being confronted by an individual armed with a formidable appearing weapon. When Hughes was told to “hand it over,” he had further opportunity to observe the defendant while he proceeded to the cash register, removed the money and placed it on the counter for defendant to pick up. After that, Hughes was required to lay on the floor. It appears reasonable to believe in that time and under those conditions, the defendant’s facial features could well be placed on record within the witness’ memory. Although defendant wore a wig, he had no mask. The opportunity to observe was present.
There is no question but that the defendant had Hughes’ attention with a handgun leveled at him. Hughes was in such a position that he had better pay attention: “I noticed that he was a nervous type person, and he began moving a little bit, so I did what he said real quick.”
With respect to the factor of the accuracy of his prior description of the criminal, the prior description given by Hughes, upon which defendant relies, was the one given at the miscarried preliminary hearing. The testimony of Hughes at the trial though was that he had previously described the defendant to arresting officers as related in footnote 2 of this opinion. At the preliminary hearing he recollected that the defendant had a mustache and was present at the preliminary hearing and the trial. The significant parts of the description at the scene and preliminary hearing had to do with his clothing, the stringy hair, the headgear and the weapon he carried. There was no suggestive identification at the preliminary hearing that would bring those matters of identification to the attention of Hughes. At the preliminary hearing the defendant was not in the same dress, wearing a hat, carrying a pistol, or adorned with a wig. There were some insignificant variations between the description of those items at the preliminary and the trial but exactness would surely create suspicion. Borrowing the approach of the Court in Manson, in recognition that it plays no part in our analysis at this point, the reliability of the identification of the defendant’s appearance at the time of the crime is hardly undermined by the corroboration found in the other evidence of defendant’s dress and other accouterments related to him at the time of arrest.
The level of certainty demonstrated at the confrontation was adequate. The testimony at the terminated preliminary hearing indicated no uncertainty. Through no fault of the State or the witness, no opportunity was afforded to test the witness’ certainty through cross examination. No showing whatsoever was made that, in light of the factors just discussed, the suggestive identification in any way corrupted the testimony of the witness Hughes. While other evidence of guilt cannot be considered at [366]*366this stage, we can consider the role of this particular witness as far as identification is concerned. The prosecutor attempted in every reasonable way he could to persuade the Justice of the Peace to hear the rest of the evidence, not only further testimony of Hughes but that of other witnesses:
“BAYLESS: I think, Your Honor, if you’ll wait and listen to the evidence you’ll find that there’s alot of independent basis for the identification and so I think the Court’s observations are premature and I think that the Court should listen to the balance of the evidence.”
There is no indication that the State was attempting in any way to influence the testimony of Hughes.
The pretrial confrontation in this case was a necessary proceeding. A fundamental part of a preliminary hearing, as well as a trial, is the presence of the defendant. Regardless of his attire, he can usually be identified by virtue of his role as the person charged. While we do not want to be understood as approving his appearance at a preliminary hearing unnecessarily attired in jail garb and handcuffed over his express objection, the necessity for identification evidence of some sort at that stage is inevitable. The function of the preliminary hearing is to ascertain whether there is “probable cause to believe that an offense has been committed and that the defendant has committed it * * Rule 7(b), W.R.Cr.P. There must be identification of some sort to relate the defendant to the crime. It is not always through eye-witnesses.
There never was any identification of the defendant other than in a courtroom. This is not the usual suggestive identification utilized to track down and arrest a violator. There is not involved a photographic lineup, a police lineup, a police station identification, an on-the-scene showup, or any other outside device to show the defendant to the witness for identification purposes. Except for his crime scene observation of the defendant, Hughes had not been afforded any opportunity until the preliminary hearing to make any identification. The objections of the defendant, followed by the abrupt outburst of the Justice and his inappropriately piqued withdrawal from the proceeding gave the State no fair opportunity at that juncture to further demonstrate the reliability of Hughes’ identification nor was the defendant afforded an opportunity to establish the unreliability of the identification. Hughes’ recollection of the defendant as seen when he was being held up with a gun in his face stands unchallenged. Manson makes it clear that a suggestive confrontation does not per se command the exclusion of the identification testimony. Further, in Manson, reversal is considered a “draconian sanction,” for cases in which the identification is reliable despite an unnecessarily suggestive procedure:
“ * * * Certainly, inflexible rules of exclusion, that may frustrate rather than promote justice, have not been viewed recently by this Court with unlimited enthusiasm. [citing cases.]” 432 U.S. at 113, 97 S.Ct. at 2252, 53 L.Ed.2d at 153.
The Court in Manson confirmed Neil v. Biggers, supra, on the question of unnecessarily suggestive identification where it elaborated upon the totality of circumstances test:
“ * * * It is, first of all, apparent that the primary evil to be avoided is ‘a very substantial likelihood of irreparable mis-identification.’ * * * ” 409 U.S. 188, 93 S.Ct. 375, 381, 34 L.Ed.2d 401, 410.
From our review of the totality of the circumstances of the pretrial identification, we cannot say that there was a “very substantial likelihood of irreparable misidenti-fication.” The burden on the defendant is not an easy one. The weight to be given to the Hughes’ identification was for the jury and not the trial court nor this court. In our judicial capacity, we must discriminate between real and fancied dangers of the miscarriage of justice.
Even assuming that there was constitutional error in the type of pretrial identification here and that it did taint the testimony of the witness Hughes, we need not accept the view of the defendant that regardless of the facts and circumstances it [367]*367must be deemed plain error requiring an automatic reversal. Rule 49, W.R.Cr.P.5 Before a federal constitutional error can be held harmless, the burden is on the State to demonstrate and the court must be able to declare a belief that it was harmless beyond a reasonable doubt. Chapman v. State of California, 1967, 386 U.S. 18, 87 S.Ct. 824, 828, 17 L.Ed.2d 705, 24 A.L.R.3d 1065. There are but few constitutional violations so basic that infraction can never be classed as harmless error.6 We cannot find that the Supreme Court of the United States has held that the substantial likelihood of mis-identification is justification in itself to declare plain error. As previously indicated, in United States v. Wade, supra, the Court recognized harmless error to be available. Foster v. California, supra, was remanded for a determination of whether there was harmless error. We turn now to applying that standard, and will conclude there can be no doubt that any error, if it existed at all, was harmless.
The courtroom identification of the defendant at the preliminary hearing has little significance. The defendant was not wearing the same clothing that he was wearing at the time Woody’s Truck Stop was robbed. He was not wearing the same kind of clothing at the time of robbery that he was wearing in the courtroom at the time of the trial. He was convicted because of the vast circumstantial evidence against him. What is significant is Hughes’ description of what he saw at the scene of the crime which was nothing like what he saw at the preliminary hearing or the trial. He described an individual in a green coat, dark pants, with a long-stringy-hair wig, wearing dark headgear and pointing a pistol at him. A policeman came, and apparently at that time Hughes did little more than state the robber was heading off in a northerly direction. See footnote 2. The individual that was apprehended had in his possession a pistol, money in the same amount as stolen, a wig, was wearing a green coat, and was apprehended in flight, all as a result of whatever it was that the station attendant told the policeman before the policeman wasted no time getting out after the criminal. Moreover, Hughes’ testimony was substantiated by other independent evidence, e. g., a cartridge case was found on the floor of the truck stop which matched the weapon taken from the defendant. The defendant showing up in prison garb and handcuffed at a preliminary hearing could not corrupt all that decisive evidence. Identification can be established by circumstantial evidence which then becomes a jury question. Johnson v. State, Wyo.1977, 562 P.2d 1294.
After we have examined the total circumstances to determine if there was an unduly prejudicial pretrial identification, upon an evaluation of the totality of surrounding circumstances, we then examine the facts for harmless error. What was the effect of all the evidence identifying the defendant as the person who robbed Woody’s Truck Stop? Reason indicates that there must be a causal connection between a “ ‘substantial likelihood of irreparable misidentification,’ ” Neil v. Biggers, supra, and the guilty verdict as viewed against the totality of the circumstances, Simmons v. United States, supra. When Hughes’ description is coupled with the sequence of events leading to the capture of defendant, the articles found in the car from which the circumstances and inferences point to his having exited, there can be no doubt of guilt. The witness Hughes could have been less than positive and even doubtful whether the defendant seated at defense table [368]*368was the robber, and still the defendant’s guilt role in the robbery would lie outside the perimeter of reasonable doubt. The view we take of identification testimony in this case can be summed up as set out in Johnson v. State, supra:
“ * * * Identification of an accused, therefore, need not be positive in order to obtain a conviction. The witness need only testify that it is his belief, opinion or judgment that the accused committed the crime. The lack of positiveness goes only to the weight of his testimony. [Citations omitted.]
“The general rule with regard to establishing an accused’s identity is stated in 77 C.J.S. Robbery § 47, p. 508:
‘ * * * Where the sum total of circumstantial evidence is sufficient, accused may be identified by his voice, or particular manner of talking, or by tracks, or footprints, or by any distinctive features of his person or apparel, or by any other evidence of a purely circumstantial character. * * * ’”
(Emphasis in original.)
Through good police work, good fortune, or a combination, the criminal suspect here was apprehended in such close proximity to the time and place of the crime that the speedy' interconnection of events quickly puts together the combination of events making identification of the defendant conclusive.
This court has many times ruled on the question of prejudicial error in criminal cases, Criminal Law, West’s Wyoming Digest, but it does not seem to have set up any standard for the determination of when there is harmless or prejudicial error. For constitutional questions, we adopt the rule of Chapman, whether under the Constitution of the United States or the Constitution of the State of Wyoming. Other than on constitutional questions, error in the admission of evidence is harmless if the facts shown by that evidence are already before the jury through other properly admitted evidence. 3 Wright, Federal Practice and Procedure: Criminal, § 854, p. 361; Guffey v. United States, 10th Cir. 1962, 310 F.2d 753.
Defendant claims error in failure of the trial court to instruct the jury on identification testimony. The defendant failed to object to refusal of the trial judge to give the offered instruction; we will not consider it on review, Raigosa v. State, Wyo. 1977, 562 P.2d 1009, unless it can be brought under the plain error doctrine, which we will not exercise except in exceptional circumstances, Hampton v. State, Wyo.1977, 558 P.2d 504. Only recently this court has confirmed its position that a request for an instruction without a distinct objection to failure of the court to so instruct, is insufficient to allow this court’s review of the alleged error. Montez v. State, Wyo.1977, 573 P.2d 34.
The burden is on the defendant to show plain error. Belondon v. City of Casper, Wyo.1969, 456 P.2d 238, cert. den. 398 U.S. 927, 90 S.Ct. 1815, 26 L.Ed.2d 89. Defendant fails to show that other instructions given by the court are inadequate to present the factual question of identification for the decision of the jury. The offered identification instructions would have admonished the jurors to use great caution in considering identification testimony, that such testimony was uncertain and less to be relied on than other types. Under the refused instructions, in appraising such testimony, the jury would have been instructed to consider opportunity to observe the offender, whether it was the product of his own recollection, the influence of subsequent identification opportunities, or confrontations between the witness and the defendant. They provided, as well, that the burden of proof on the prosecutor to prove the crime beyond a reasonable doubt specifically includes the identity of the defendant and presence of bias and prejudice resulting from previous confrontations.
The trial judge gave complete instructions including directions that the jury was the sole judge of the credibility of the witnesses and weight to be given their testimony, to consider the means of knowledge of facts testified to, the reasonable[369]*369ness of testimony, whether contradicted, any prejudice shown by the evidence, and to consider all the facts and circumstances in the case. The court, through several instructions, admonished the jury as to the duty of the State to prove beyond a reasonable doubt that the defendant committed the crime charged. It is not error to refuse requested instructions which are otherwise covered by other instructions, even though the principles embodied are correct. Benson v. State, Wyo.1977, 571 P.2d 595.
Affirmed.
