opinion: DANAHER, Circuit Judge.
  Jointly indicted, Stevenson and Borum after a jury trial were found guilty of housebreaking and robbery. Both contend on appeal that the trial court erred in denying their respective motions for judgments of acquittal at the close of the Government’s case. Additionally, Borum contends that fingerprint evidence of his complicity was erroneously received because comparison had been based upon fingerprints retained after an earlier conviction which had been “set aside following his satisfying the conditions of his sentence under the Youth Offender” statute. The appeals have been consolidated for presentation in this court.
  On July 2, 1965, one Davis received word, and presently confirmed that his house had been forcibly entered. Its contents were in great disarray, and many items of value had been stolen. Money had been taken from a metal box, from underneath a glass top on a bedside table, and from a tea canister. Davis knew neither appellant and had never given them permission to enter his home.
  A Metropolitan Police Department expert on July 2, 1965 had removed several fingerprints from the various named objects, each of which had been in the Davis home for some three to twelve years. Three prints were identical to known fingerprints of the appellant Borum, two having been lifted from the metal box and the third from the bedside table glass. A fourth fingerprint identical to a known fingerprint of the appellant Stevenson, had been lifted from the bottom of the tea canister.
  Stevenson has argued that his conviction can not be sustained since there was no showing that his fingerprint had been placed on the container on July 2, 1965 or that the container was located on the premises when the Stevenson print was superimposed. Thus, he contends, the evidence was insufficient to justify his conviction. The trial court instructed the jury that before a verdict of guilty could be returned, the jurors must be satisfied beyond a reasonable doubt that the housebreaking and robbery had occurred on July 2, 1965 as had been testified, and that Stevenson was one of those who had perpetrated the crimes.
  An officer testified that when he arrived at the house about 10:30 in the morning of July 2, 1965, “Everything was strewn all over the house, there were things out all over the bed and in the living room.” He proceeded to lift fingerprints from various objects. Stevenson was arrested the following evening, and some two to three hours later was fingerprinted by the police. The officer compared the known prints thus secured with that taken from the tea canister. The prints were identical, the expert testified, and both were prints made by Stevenson. He argues now that the evidence was insufficient to permit a jury to return a guilty verdict. We do not agree. Stevenson did not testify, and there was no suggestion from any source that Stevenson on any account could have had legitimate access to the canister upon which his fingerprints had been found.
  A like argument has been advanced by Stevenson’s brother-in-law, the appellant Borum. Like Stevenson, Borum did not testify.
  Under correct instructions the jury was bound to weigh the evidence and from such facts as it might find, to draw appropriate inferences respecting the guilt of the appellants. It is abundantly clear that the jury properly might conclude that Davis’s house had been burglarized on July 2, 1965; that the thieves had left their fingerprints as found by the police; and that the identification of the two accused had been adequately established.
  Fingerprint identification has long been recognized by the courts as entirely appropriate. The accuracy of fingerprint identification is a matter of common knowledge and no case has been cited, and we have found none, where identification so established has been rejected. Under the circumstances here shown, the jury was fully justified in concluding that these two appellants in the course of their crime had impressed their fingerprints upon the objects described in a location to which the appellants had been accorded no lawful access. We reject the contentions of the respective appellants that the evidence was insufficient to establish their complicity, as charged.
  Borum additionally has contended that enlarged photographs of Borum’s prints taken at the scene of the crime could not properly have been received in evidence, since identification of those prints had stemmed from similar prints acquired by the Government following Borum’s earlier arrest. The trial judge pointed out in colloquy with defense counsel that she did not agree that the Government is “not entitled to use the fingerprint because * * * [Borum’s] conviction under the Youth Corrections Act has been wiped out.” Over objection exhibits of Borum’s fingerprints taken on July 6, 1965 were then introduced.
  Borum would have us say that the fingerprints which led to his identification when compared with those found in the Davis premises on July 2, 1965 were unlawfully used. He quite misreads the intendment as well as the language of the Federal Youth Corrections Act upon which he relies. 18 U.S.C. § 5006(h) (1964) defines “conviction” to mean “the judgment on a verdict or finding of guilty, a plea of guilty, or a plea of nolo contendere.” Section 5021(a) provides that upon
  “the unconditional discharge by the division of a committed youth offender before the expiration of the maximum sentence imposed upon him, the conviction shall be automatically set aside and the division shall issue to the youth offender a certificate to that effect.” (Emphasis added.)
  It is quite so that the Act is to be applied to one who may be deemed a fit subject for rehabilitation. In the event that the youthful offender by virtue of his own good conduct shall have satisfied the prescribed conditions, he may be spared the lifelong burden of a criminal record. Setting aside a “conviction” in accordance with the terms of the Act can obviously redound to the great advantage of the accused.
  But the Act calls for no more than that the “conviction” shall be set aside, the appropriate conditions having been met.
  If a court finds that a youth offender will not derive benefit from treatment under the Youth Corrections Act, the court may sentence that offender under whatever penalty provision is otherwise applicable. On the other hand, that a judge may decide that a particular offender may possibly be amenable to rehabilitation in nowise eliminates the fact that in either event, the accused will have been arrested, booked, photographed and fingerprinted as an incident to his arrest.
  We find no merit in the contention that the later setting aside of a conviction will obliterate the earlier consequences under discussion. We reject the Borum argument. Rather it is so that the Government here may properly have recourse to his fingerprints in furtherance of the congressional purpose that Borum’s identification records be used for the detection and prosecution of crime. It follows that there was no error on the part of the trial judge in admitting in evidence the fingerprints taken in the instant ease even though Borum had been identified following their comparison with those obtained at the time of Borum’s earlier arrest.
  The convictions herein considered are Affirmed.
  . 18 U.S.C. § 5021(a) provides “[u]pon the unconditional discharge by the Division of a committed youth offender before the expiration of the maximum sen-tenee imposed upon him, the conviction shall be automatically set aside and the Division shall issue to the youth offender a certificate to that effect.”
  . The thieves robbed Davis’s mother-in-law, one Effie Thomas, of some $23.25. She was a nearly-blind 81-year-old lady who undertook no identification of the intruders who robbed her.
  . Of course where the presence of fingerprints has been susceptible of explanation offered by the accused conviction does not necessarily follow. Cooper v. United States, 94 U.S.App.D.C. 343, 218 F.2d 39 (1954); but see Mason v. Commonwealth, 357 S.W.2d 667 (Ky.1962); compare Hiet v. United States, 124 U.S.App.D.C. 313, 365 F.2d 504 (1966), where the trial judge deemed the evidence overwhelming and that the fingerprints of the accused established his guilt. On appeal, one judge agreed with the trier, one considered the fingerprint evidence insufficient, and a third judge agreed to reverse because of prejudicial delay on the part of the prosecution.
  . Fingerprinting
  “is known to be a very certain means devised by modern science to reach the desired end, and has become especially important in a time when increased population and vast aggregations of people in urban centers have rendered the notoriety of the individual in the community no longer a ready means of identification.” United States v. Kelly, 55 F.2d 67, 69, 83 A.L.R. 122 (2 Cir. 1932).
  And see United States v. Krapf, 285 F.2d 647, 650 (3 Cir. 1961).
  . For informational background, see State v. Kuhl, 42 Nev. 185, 175 P. 190, 3 A.L.R. 1694 (1918).
  . Other methods, but none superior to fingerprinting have been employed over the years where the courts were concerned with problems of identification. See, e. g., Shaffer v. United States, 24 App.D.C. 417, 425, 426 (1904) ; United States v. Kelly, supra note 4; State v. Kuhl, supra note 5.
  . See generally, Bridges, “Practical Fingerprinting” (1963) as to the “invincibility” of the identification so shown. See also 5 U.S.C. § 300 (1964) and note 12 infra.
  . The initial identification of Borum had stemmed from comparison of the fingerprints found in the Davis home July 2, 1965, with those already on file. Defense counsel stated: “As long as the record is clear, Your Honor, so it can be preserved for the Court of Appeals, that is all I am interested in.”
  . Bynum v. United States, 104 U.S.App.D.C. 368, 265 F.2d 465 (1958) is of no help to the appellant. We held there that the Fourth Amendment rights of the accused were paramount. Since there had been no probable cause for the arrest of Bynum, the Government was not entitled to use as evidence the fingerprints thereupon secured.
  . Tatum v. United States, 114 U.S.App.D.C. 49, 51, 310 F.2d 854, 856 (1962). And that was its purpose as Judges Parker and Phillips testified. Hearings, Senate Subcommittee on the Judiciary, 81st Cong., 1st Sess. (1949).
  . For example, under D.C.Code § 22-3204 (1961), a first offender might have a record of conviction of a misdemeanor, only, with imprisonment for not more than one year, but for a second offense under that section he might be sentenced to imprisonment for not more than ten years. Again, were an accused to violate the narcotics laws, 26 U.S.C. § 7237 (1964) provides ever-increasing penalties for a second offense and for a third or subsequent offense. Obviously, setting aside a first “conviction” under the Youth Corrections Act can be truly meaningful.
  . See 5 U.S.C. § 300 (1964); as Chief Judge Biggs pointed out in United States v. Krapf, supra note 4, the Department of Justice [and now, the Attorney General, 5 U.S.C. § 300] had been charged with the means and authority necessary to acquire, collect, clarify and preserve identification and other records for use in the detection and prosecution of crime. Pursuant thereto the United States Marshals Manual explicitly directs that one charged with violation of federal law be fingerprinted and that the fingerprints be forwarded to the Department. And section 702.02 of the Manual further provides that “Fingerprint records may not in any case be returned to a defendant, whether or not he is acquitted of the charge against him.”
  Judge Biggs further observed as had other judicial writers that “It must be remembered that fingerprinting is not a punishment but a procedure, the purpose of which is to facilitate law enforcement.” 285 F.2d at 651.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  In some cases there is some confusion over who should be listed as the appellant and who as the respondent. This confusion is primarily the result of the presence of multiple docket numbers consolidated into a single appeal that is disposed of by a single opinion. Most frequently, this occurs when there are cross appeals and/or when one litigant sued (or was sued by) multiple litigants that were originally filed in district court as separate actions. The coding rule followed in such cases should be to go strictly by the designation provided in the title of the case. The first person listed in the title as the appellant should be coded as the appellant even if they subsequently appeared in a second docket number as the respondent and regardless of who was characterized as the appellant in the opinion.
  To clarify the coding conventions, consider the following hypothetical case in which the US Justice Department sues a labor union to strike down a racially discriminatory seniority system and the corporation (siding with the position of its union) simultaneously sues the government to get an injunction to block enforcement of the relevant civil rights law. From a district court decision that consolidated the two suits and declared the seniority system illegal but refused to impose financial penalties on the union, the corporation appeals and the government and union file cross appeals from the decision in the suit brought by the government. Assume the case was listed in the Federal Reporter as follows:
  United States of America,
  Plaintiff, Appellant
  v
  International Brotherhood of Widget Workers,AFL-CIO
  Defendant, Appellee.
  International Brotherhood of Widget Workers,AFL-CIO
  Defendants, Cross-appellants
  v
  United States of America.
  Widgets, Inc. & Susan Kuersten Sheehan, President & Chairman
  of the Board
  Plaintiff, Appellants,
  v
  United States of America,
  Defendant, Appellee.
  This case should be coded as follows:Appellant = United States, Respondents = International Brotherhood of Widget Workers Widgets, Inc., Total number of appellants = 1, Number of appellants that fall into the category "the federal government, its agencies, and officials" = 1, Total number of respondents = 3, Number of respondents that fall into the category "private business and its executives" = 2, Number of respondents that fall into the category "groups and associations" = 1.
  Your task is to identify the state of the first listed state or local government agency that is an appellant.
