Bates was indicted for murder and as an accessory after the fact to murder. 1 He was found guilty as an accessory. On ap *586 peal, Bates challenges the district court’s refusal to permit him access to the transcript of the juvenile delinquency hearing of Herbert Yazzie. Yazzie, the primary witness against Bаtes, had been adjudicated a delinquent for the same murder. Bates also complains of certain subject matter restrictions placed on his exploration of Yazzie’s prior bad acts and inconsistent statements.
Bates was unquestionably at the murder scene and involved in activities related to the murder. He convinced the jury that he was not an active participant in the murder itself, but he was unable to persuade the jury that his admitted actions after the fact were taken only out of fear of Yazzie.
I.
On the night of Jаnuary 21, 1978, a truck containing Bates, Yazzie and Jeffrey Ben-nalyson slid into a ditch along a muddy road. After refusing to provide assistance to the Bates group, another motorist, Palmer, was stabbed to death. The trial testimony of Yazzie and Bates differed significantly about thosе events, and Bennalyson was unavailable to provide an additional eyewitness view. 2
Yazzie testified that, after Palmer refused to help and made a comment about a gun, Bates pulled Palmer from the car, threw him to the ground, and kicked him like a football. Yazzie held Palmer while Bennalyson stabbed him and then Yazzie in turn stabbed him several more times. Bates came to the scene, jumped up and down on Palmer’s back, grabbed the knife, and also stabbed Palmer. After an unsuccessful attempt to have people in a neаrby trailer call the police to report the body, the three men dragged the body into the roadside ditch.
Bates testified that, after Palmer refused to' help and threatened to shoot the Yazzie group, he and Palmer engaged in a short fight. Yazzie stayed with Palmer while Bates used Palmer’s car to pull the truck from the ditch. Later, after seeing that Yazzie had stabbed Palmer, Bates helped drag and cover the body only because Bates was afraid of Yazzie. Yazzie appeared to be dazed, and he had previously threatened to shoot Bates. Bates’ version was that throughout these proceedings, Benallyson remained asleep in the truck.
II.
Bates claims that, because the court denied him the transcript of Yazzie’s juvenile delinquency proceeding, his defensе was improperly limited. In particular, Bates argues that the transcript may have contained prior inconsistent statements of Yaz-zie and other impeaching evidence. In addition, the transcript may have aided trial preparation and may have further “revealed the violent, incredible nature of Herbert Yazzie or may have supported the coercion defense of the defendant.” Brief for Appellant at 8-9.
Although the government had a copy of the transcript 3 and did not object to the defendant’s motions, the district court ruled that 18 U.S.C. § 5038 precludes granting adult dеfendants access to juvenile proceeding transcripts. 4 Section 5038 does re-
*587 quire the sealing of “the entire file and record of [the juvenile] proceeding” and prohibits later release, other than to meet an enumerated exception. 5 The first listed exceptiоn in the statute, however, appears on its face to provide authority for granting Bates’ request. It allows release in response to “inquiries received from another court of law.” 18 U.S.C. § 5038(a)(1).
We understand the government’s concern that, if exceptions to thе rule of confidentiality in juvenile proceedings are broadly interpreted, the very nature of juvenile proceedings will be changed.

However, the court-inquiry exception need not be strained to cover the special circumstances of this cаse.

When “the juvenile himself was involved in the transaction on which the prosecution of the defendant is based,”
United States v. Chacon,
When the district court obtains the transcript, under the authorization of § 5038(a)(1), it should then examine the transcript
in camera
and release only the information that is of “exculpatory or impeachment value” to the adult defendant.
United States v. Chacon,
We do not feel it necessary to discuss in detail the constitutional underpinnings that mandate a liberal policy of release where the juvenile is a significant prosecution witness. It is sufficient to note that the Confrontation Clause protects Bates’ access to impeachment materials in the transcript.
See Davis v. Alaska,
We do not believe that the lengthy cross-examination of Yazzie renders the denial of the transcript harmless error. The government argues that Yazzie’s perceptions and biases were “exhaustively and professionally еxplored,” and that “further impeachment . . . was unnecessary.” Brief for Appellee at 18. However, much of the Yazzie cross-examination necessarily related to the murder charge, and the jury apparently had reasonable doubts about that portion of Yazzie’s testimony. We cannot say beyond a reasonable doubt that further impeachment materials would not have destroyed Yazzie’s remaining credibility.
See Chapman v. California,
Since material with possible exculpatory or impeachment value was not made available to the defendant in this case, we must remand for disclosure to the defendant of all such material and for a new trial.
III.
Bates urges that, in addition to the denial of the juvenile proceeding transcript, other improper restrictions were placed on his cross-examination of F.B.I. agent Baxter and of Yazzie and on his own testimony. In pаrticular, Bates was denied the opportunity (1) to question Baxter about statements Yazzie made to him; (2) to question Yazzie about a prior automobile theft arrest and about an alleged prior shooting incident; and (3) to testify himself regarding that incident. We find no general abuse of the wide discretion the trial court has in fixing the scope of cross-examination,
see United States v. Speir,
*589 Bates was permitted to tеstify and to question Yazzie about a threat against Bates alleged to have been made by Yazzie in 1977. Record, vol. 4, at 279, 404. He was not permitted to testify or to ask Yaz-zie about a shooting which occurred the same night. Id. The jury was properly instructed on Bates’ cоercion defense, which requires a “well-founded fear of impending death or serious bodily injury.” Record, vol. 4, at 521. The threat and the alleged shooting in 1977, coupled with Yazzie’s admitted actions on the night of the Palmer murder, could support a finding of “well-founded fear.” The jury might well disbelieve such a posited fear — particularly given Bates’ voluntary association with Yazzie on the night in question — but the alleged shooting incident was clearly relevant to an essential element of Bates’ defense.
IV.
As his final point on appeal, Bates charges that the district court committed plain error by admitting his inculpatory statements without a full suppression hearing. We need not resolve this issue, however, because of our, treatment of the juvenile proceeding transcript question. Since the case must be retried, we assume that, upon proper motions, all necessary hearings will be held.
REVERSED.
Notes
. Bates was convicted under 18 U.S.C. §§ 3, 1153. Both the victim and the alleged assail *586 ants were American Indians, and the crime occurred in Indian country. Federal jurisdiction is not challenged. Record, vol. 3, at 156, 158.
. Bennalyson, who had also been indicted both as a principal and as an accessory after the fact, was killed in an accident before trial.
. The government agreed at oral argument that no statutory exception permitted the Unitеd States Attorney alone to receive the transcript. The Assistant United States Attorney stated that-he had not relied on the transcript and, indeed, had not even looked at it, although there was no ruling or other prohibition against his doing so. Record, vol. 3, at 342.
. The cоurt initially read § 5038 very expansively even to preclude admission of any exhibits used in the juvenile proceeding. See Record, vol. 3, at 213-15. The court later relented somewhat and permitted the use of some materials for impeachment purposes only. See id. at 221, 229.
In support of the denial of the transcript, the court also cited Fed.R.Evid. 609(d), Record, vol. 3, at 49-50, which makes “evidence of juvenile adjudication . . . generally not admissi *587 ble.” However, this provision falls within a rule dealing with “Impeachment by Evidence of Conviction of Crime”; at issue in this case is not admission of the fact of adjudication. Indeed, Yazzie’s connection with the crime was clear from his own testimony. Moreover, a rule of evidence does not provide authority to refuse disclosure for nonevidentiary purposes.
. Section 5038(a) provides:
Throughout the juvenile delinquency proceeding the court shall safeguard the records from disclosure. Upon the completion of any juvenile delinquency proceeding whether or not there is an adjudication the district court shall order the entire file and reсord of such proceeding sealed. After such sealing, the court shall not release these records except to the extent necessary to meet the following circumstances:
(1) inquiries received from another court of law;
(2) inquiries from an agency preparing a presentence report for another court;
(3) inquiries from law enforcement agencies where the request for information is related to the investigation of a crime or a position within that agency;
(4) inquiries, in writing, from the director of a treatment agency or the director of a fаcility to which the juvenile has been committed by the court;
(5) inquiries from an agency considering the person for a position immediately and directly affecting the national security; and
(6) inquiries from any victim of such juvenile delinquency, or if the victim is deceased from the immеdiate family of such victim, related to the final disposition of such juvenile by the court in accordance with section 5037.
Unless otherwise authorized by this section, information about the sealed record may not be released when the request for information is relаted to an application for employment, license, bonding, or any civil right or privilege. Responses to such inquiries shall not be different from responses made about persons who have never been involved in a delinquency proceeding.
. Confidentiality encourages “the juvenile to discuss his actions freely and completely so that rehabilitation can commence without delay.”
United States v. Chacon,
. Legislative documents are unfortunately of little help in determining the precise boundaries of § 5038. See S.Rep.No.1011, 93d Cong., 2d Sess., reprinted in [1974] U.S.Code Cong. & Admin.News, pp. 5283, 5321. The government argues that, because Congress must have known that juveniles and adults are often involved in crimes together, the absence of a specific statutory exception to cover use at adult trials is significant. Brief for Appellee at 15. We will not hobble our interpretаtion of statutes with the requirement that every circumstance meant to be covered must be specifically mentioned.

the Court stressed that “the right of confrontation is paramount to the . . . policy of protecting a juvenile offender.”
