Opinion for the Court filed by Circuit Judge WALD.
A jury сonvicted Dennis S. Davis and Bobby A. Holton of crimes involving the unlawful possession and distribution of crack cocaine, conspiracy and the unlawful use of a communications facility. On appeal, both appellants challenge their convictions on the basis of alleged errors made by the district court when it (1) permitted the jurors to consider government-prepared transcripts of drug transactions during deliberations; (2) replayed recorded drug transactions for the jury during deliberations without the defendants being present; (3) refused to voir dire the jury about possible prejudice stemming from a television news program; and (4) determined that handwritten notes made by a government witness were not producible *1539 Jencks Act material. In addition, appellants contend that the Fifth Amendment requires a remand for resentencing under the guidelines applicable to individuals who have committed crimes involving powder cocaine. Finding none of these claims meritorious, we affirm the convictions and sentences.
I. Background
In October 1991, a confidential informant advised the Metropolitan Police Department (“MPD”) that individuals were selling drugs at the Barry Farms housing complex in southeast Washington, D.C. The MPD launched an undercover investigation in which MPD Detective Michael J. Quander posed as the brother of the confidential informant in order to gain an introduction to the drug dealers. Detective Quander made six trips to the Barry Farms complex during which he purchased approximately 11 ounces of crack cocaine. Following the last purchase, the police executed search warrants at two homes in the complex and seized additional drugs and drug paraphernalia. They arrested apрellants Dennis S. Davis, Bobby A. Holton and several others.
The government’s evidence against appellants included body-wire tape recordings of conversations between Detective Quander and the individuals with whom he engaged in drug transactions. A trial was held at which the body-wire tapes were admitted into evidence but, based on an agreement between the parties, were never played to the jury. Appellants were convicted of all the charges against them. On appeal, this court vacated the convictions against appellants and remanded the ease for a new trial.
At the second trial, the government announced its intention to play portions of the body-wire recordings to the jury. Defense counsel unsuccessfully moved to have the tapes, excluded because of their poor quality. Just prior to calling Detective Quander to the witness stand, the government informed the court that it had not yet prepared transcripts of the tape recordings. The trial was recessed so that the government and defense counsel could listen to the tape recordings and the government could prepare transcriptions of the recordings. When presented with the government’s transcripts, defendants objected to their accuracy, arguing that the tapes were inaudible in many parts and that, because defendants denied involvement in the drug transactions, the attribution of statements to them would be prejudicial. Appellant Davis’ counsel proffered an alternative version of the transcript that eliminated the attributions and substituted “inaudible” for some of the statements. At the government’s request, the court listened to the tape recordings while reading along with the government-prepared transcripts. The court heard objections from the defendants and ruled that the government transcripts of the recordings would aid the jury in listening to the tapes during the trial, but that the transcripts themselves would not be given to the jury during its deliberations.
The tapes were played and authenticated during the examination of Detective Quan-der. The government-prepared transcriptions were distributed to the jury before the tapes were played and were collected directly afterwards. On cross-examination of the detective, it was revealed that Detective Quan-der had prepared handwritten notes or transcriptions of the tape recordings. Defense counsel made a Jencks Act request for the written notes, but the district court concluded that the documents did not constitute Jencks material and refused to hold a hearing. At defense counsel’s request, however, the court agreed to examine the documents in camera and ordered that the government file the handwritten notes under seal so that they could be examined on appeal.
The evening after the defendants began presenting their cases, ABC News showed a Nightline program concerning the disparate sentences imposed for crimes involving powder cocaine and those involving cocaine base or crack cocaine. Among the individuals interviewed on the program were District of Columbia Superior Court Judge Reggie Walton and Michelle Roberts, a criminal defense attorney who practices in the District of Columbia. Judge Walton talked about patterns of violent behavior related to the crack cocainе trade and speculated that high mandatory sentences may have contributed to the lowering of the homicide rate in Washington, *1540 D.C. Ms. Roberts criticized the sentencing structure for crimes involving crack cocaine as lacking deterrent value. When trial resumed the following morning, counsel for appellant Holton requested that the district judge voir dire the jury in order to determine whether any of the jurors had viewed the television program and, if so, what impact it might have on their deliberations. The district court refused to question the jurors because they had been probed about their ability to be fair and impartial during jury selection and frequently had been admonished not to decide the case based on anything heard outside of the courtroom.
After deliberations began, the court received notes from the jury asking to hear all of the tape rеcordings. The district judge consulted with counsel and arranged a procedure whereby his law clerk would play the tapes for the jury in the courtroom — which the judge described as “an extension of the jury room” — and distribute the transcripts as listening aids, to be collected at the completion of the playing of the tapes. Defense counsel objected to the jurors receiving-the transcripts during deliberations because the transcripts had not been admitted into evidence, were not accurate and because the court had stated that the jury would not be given the transcripts during deliberations.
Appellant Holton was convicted of one count of Conspiracy to Distribute Cocaine Base in violation of 21 U.S.C. §§ 846 and 841, four counts of Unlawful Distribution of Cocaine Base Within 1000 Feet of a Playground and School in violation of 21 U.S.C. § 860(a) and 18 U.S.C. § 2, аnd one count of Unlawful Use of a Communication Facility in violation of 21 U.S.C. § 843(b). Appellant Davis was convicted of one count of Conspiracy to Distribute Cocaine Base in violation of 21 U.S.C. §§ 846 and 841, six counts of Unlawful Distribution of Cocaine Base Within 1000 Feet of a Playground and School in violation of 21 U.S.C. § 860(a) and 18 U.S.C. § 2, and one count of Unlawful Use of a Communication Facility in violation of 21 U.S.C. § 843(b). The court sentenced appellant Holton to concurrent terms of 363 months imprisonment for the conspiracy and distribution offenses and 48 months imprisonment for the communication facility offense, and appellant Davis to concurrent terms of 370 months imprisonment for the conspiracy and distribution offenses and 48 months imprisonment for the communication facility offense. These consolidated appeals ensued.
II. Discussion
A. Use of Transcripts and Replaying of Tapes During Jury Deliberations
1. Transcripts
A transcript repeating in written form a conversation recorded on tape may help a juror listening to the tape follow the conversation when the tape is of questionable clarity,
see United States v. West,
The principal risk of indiscriminately permitting the use of transcripts by jurors is that in the case of a poor quality or unintelligible recording, the jurors may substitute the contents of the more accessible, printed dialogue for the sounds they cannot readily hear or distinguish on the tape and, in so doing, transform the transcript into independent evidence of the recorded statements.
See United States v. Howard,
These risks can be markedly decreased when certain precautions are taken. Thus, we have upheld the practice of giving the jury a transcript to help follow a tape recording played during trial so long as procedures are followed to ensure that the jury does not rely on one party’s version of the transcript instead of the tapе recording.
See Slade,
We have not previously adopted any rule regarding the use of the transcript by the jury during its deliberations or indeed for the admission of a transcript into evidence so that, like any other piece of evidence, it can be brought into the jury deliberations.
See Dallago v. United States,
Our survey of the practices of other circuits indicates that permissible procedures regarding transcripts vary widely. Some circuits have permitted transcripts to be brought into deliberations without requiring
*1542
that they be formally admitted into evidence.
See, e.g., United States v. Capers,
To protect jury deliberations from improper influence, we ordinarily restrict the jury’s access only to exhibits that have been accepted into evidence and “consideration by the jury of documents not in evidence is error....”
United States v. Treadwell,
Our precedents indicate that it is permissible to present the jury either with an “accurate” transcript or two alternative transcripts. We believe that the best practice remains for the parties to dеvise a stipulated transcript.
See Onori,
To sum up: The district court, in the exercise of its discretion, should decide whether transcripts should be admitted into evidence as an aid to the jury. It is within the. district court’s discretion to decide whether, upon request of the jury to hear tape replays, it will permit the jury to use the transcripts during deliberations. The court should reach a decision in this respect sufficiently early in the trial to allow defense counsel an opportunity to challenge the accuracy of any government-prepared transcript, to support the accuracy of any alternative transcript that the defendant wishes to introduce, to raise objections, and to request appropriate jury instructions. Upon an objection of one of the parties, and failing agreement between the parties on a stipulated transcript, each party should be permitted an opportunity to introduce its own transcript or the parties should creаte a single transcript that shows both versions at the points of disagreement. When the jury receives two transcripts of the same recording, it should be instructed that there is a difference of opinion as to the accuracy of the transcripts and that it is up to them to decide which, if any; version to accept. The jurors also should be instructed that they should disregard any portion of the transcript or transcripts that they think differs from what they hear on the tape recording. Further limiting instructions will depend on the circumstances of the case.
Although we recognize that the district court could not have anticipated the rule we lay down today, we find that the court failed to meet the standards previously set forth in Slade for the use of a transcript during trial. A careful reading of the transcript reveals that the trial judge acknowledged that the tapеs were sufficiently audible and intelligible to be played to the jury and that the transcripts would aid the jury in listening to the tapes, but that he never explicitly found that the transcripts accurately reflected statements recorded on the tapes or that the attributions in the transcripts were accurate.
The trial judge did indeed listen to each tape recording while he read the government-prepared transcripts. After playing the October 4, 1991 tape for the judge, the government stated “I would suggest that the court can now find that not only are the excerpts that the government intends to play audible and intelligible, but that the material on the tape that the government intends to play is highly probative.... ” After making two changes to the transcript of the October 4, 1991 tape, the government stated that it “stands by its transcript 100 percent.” The court ruled “I am satisfied and make essentially the findings that are articulated by [the government] with respect to the October 4th transcript.” Because the only proposed findings articulated by the government related to the quality of the tape, not the transcript, we are unable to conclude that the judge verified the accuracy of the transcript. After playing the October 16, 1991 tape, the government stated its belief that its transcript “is the appropriate transcript to aid the jury in playing these tapes.” The court agreed but did not state that the transcript was accurate. The court appears to have made the same “finding” with respect to the transcript of the October 23,1991 recording and the transcript of the October 30, 1991, recording. The court never ruled on any of the specific objections that were raised by defense counsel.
Despite оur skepticism, it is possible that the court’s “findings” could be interpreted as verifying the accuracy of the transcripts. There was no way, however, for the judge to know whether the attribution of certain voices to certain defendants was accurate; Detective Quander had not yet testified as to *1544 the identity of the speakers and the defendants had not testified. Nor did the district judge condition his accuracy “finding” on subsequent proof that the attributions were correct or ever revisit the issue. We must conclude, therefore, that the district judge did not follow any of the procedures described in Slade that must precede the jurors being given the transcripts.
The immediate question then is whether the court’s error in placing the transcripts before the jury during deliberations requires reversal of the convictions. As we discussed above, we restrict the jury’s access to information in order to protect the jury’s delibеrations from improper influence. If there was an intrusion in the jury room that did not result in harm, then reversal would be pointless.
See United States v. Olano,
The facts of this case do not suggest that the court should presume prejudice or that there is a reasonable probability that the jury was prejudiced by the transcripts. The record “provides substantial support for the relative accuracy of the transcripts.”
Slade,
Appellants insist that the court’s “about-face” with respect to the jury having the transcripts during deliberations compromised defense counsel’s ability to highlight alleged inaccuracies or present alternative transcripts, but the facts simply do not bear out such a claim. Defense counsel seized the opportunity to challenge the preparation and accuracy of the government-prepared transcripts during their cross-examination of Detective Quander and during their closing arguments. Thus, “the jury was made aware that the transcripts offered only the government’s interpretations” of the tape recordings,
Slade,
The district court’s frequent limiting instructions also served to avert the possibility of prejudice. The court instructed the jury prior to the distribution of each transcript and at the close of trial that the transcripts were not to be considered independent evidence and that only the tape recordings constituted evidence of the conversations recorded therein.
1
The jury was
*1545
also provided with a written instruction as to the limited use to be made of the transcripts and was referred to that instruction by the judge when he informed the jury that arrangements had been made for them to hear the tapes.
2
See United States v. Crowder,
Finally, it is clear that the jury did not use the transcripts as a substitute for listening to the tapes in deliberations. The record indicates that the transcripts were made available only in conjunction with the relevant tape recordings and the record suggests that the jury did listen to the tapes being replayed during deliberations.
Cf. United States v. Collazo,
Appellants argue that by allowing the transcripts to be seen and read by the jury, the district court violated the best evidence rule, which requires the production of an original recording, when available, to prove its contents. Fed.R.Evid. 1002. We note that the bеst evidence rule would not be implicated in circumstances in which the district court follows the proper procedure. “The elementary wisdom of the best evidence rule rests on the fact that the [recording itself] is a more reliable, complete and accurate source of information as to its contents and meaning than anyone’s description [of it].”
Gordon v. United States,
2. Replaying of Tapes
Appellants also challenge the trial court’s decision to replay the tapes for the jury during deliberations when neither they nor their attorneys were present. They argue that they were denied their Sixth Amendment right to confront the evidence against them and their Fifth Amendment right to due process. The government asserts that defendants’ counsel agreed with the district court’s proposal that only his law clerk be present, but the trial transcript is decidedly vague on that point, probably because there were prior discussions off the record between the lawyers and the judge which are not a matter of record.
First, appellants speculate about problems that
might
have occurred during the replaying, which was conducted in the courtroom by the judge’s law clerk according to procedures of which both parties were informed beforehand. But, there is in fact no evidence suggesting that the law clerk either made independent decisions about whether or how to replay tapes or remained
*1546
in the сourtroom while the jury was deliberating, except for the actual playing of the tapes. Under these circumstances, there is no reason to presume harm.
See United States v. Sobamowo,
Second, appellants assert that
Soba-mowo
requires supervision by defense counsel during the replaying of tapes. In that case, the court reasoned that the district court’s procedure requiring the presence of the prosecution and at least one defense attorney rendered any potential error harmless. In that same case, however, we held that “tape replaying [for the jury during deliberations is] not a stage of trial implicating the confrontation clause or Rule 43(a).”
Sobamowo,
B. Jencks Act Claims
Appellants contend that the district court committed reversible error when it denied appellant Davis’ request — under the Jencks Act, 18 U.S.C. § 3500 (1988) — for documents created by Detective Quander during the course of preparing the transcripts of the body-wire recordings. The Jencks Act provides, in pertinent part:
(b) After a witness called by the United States has testified on direct examination, the court shall, on motion of the defendant, order the United States to produce any statement (as hereinafter defined) of the witness ... which relates to the subject matter as to which the witness has testified. ...
* * * * * *
(e) The term “statement,” as used in subsection[ ] (b) ... of this section in relation to any witness called by the United States, means—
(1) a written statement made by said witness and signed or otherwise adopted or approved by him....
Id.
§§ 3500(b), 3500(e). The Act ‘Vas intended to enable the defense to impeach a government witness by bringing any [ ] variances [between Jencks material and the witness’s testimony] to the attention of [the finder of fact].”
Norinsberg Corp. v. United States Dep’t of Agriculture,
The trial court has a duty under the Jencks Act to engage in an adequate inquiry into the nature of documents requested before ruling against Jencks Act production.
United States v. North American Reporting, Inc.,
After careful review of the documents belatedly supplied by the government we find the attributions and the statements reflected in Detective Quander’s handwritten notes to be entirely consistent with his testimony on the witness stand and we cannot conceive of any reasonable basis on which appellant was prejudiced by his inability to inspect the notes before Detective Quander testified. Thus, the government’s failure to produce the documents had no actual consequence. When the information contained in undisclosed Jencks materials does not vary from that provided by the witness at trial, “it would offend common sense and the fair administration of justice to order a new trial.”
Rosenberg v. United States,
C. Jury Contamination
Every criminal defendant is entitled to an impartial jury, as free as practicable from extraneous influences that could subvert the fact-finding process. Appellant Holton claims he was denied that right because, on the evening after the defendants began to present their cases, members of the jury may have seen a Nightline program dealing with sentencing standards for crack cocaine offenses. During the broadcast, the link between crack and violence was discussed extensively. Holton particularly targets a televised comment by District of Columbia Superior Court Judge Reggie Walton that credited high sentences for crack offenses with a reduction in the murder rate in the District of Columbia. The program did not refer specifically to anyone involved in this case.
There is no general presumption of prejudice where jurors are exposed to media coverage about the case on which they are sitting,
United States v. Williams-Davis,
First, courts must determine if the nature of the news material in question is innately prejudicial. Courts are more likely to find publicity prejudicial if it was broadcast close to the time of trial, discussed information that would have been inadmissible at trial, reported on the outcome of proceedings against co-defendants, or was inflammatory.
See, e.g., Salemme v. Ristaino,
In this case, the Nightline broadcast was a half-hour national network program televised midway through appellants’ trial at 11:30 p.m. (a promotional trailer may have appeared earlier in the evening). The focus on the Nightline show was the level of sentencing for crimes involving crack cocaine. Although it dealt with an issue that collaterally affected the defendants, it had nothing to do with their guilt (which they stoically denied) and prejudice to their individual defenses was extremely unlikely. We agree with the district court that its frequent reminders to the jury not to consider information gleaned outside of the courtroom also acted to stem any conceivable prejudicial inferences a viewer might take away from the program about sentencing in crack cases generally. In light of the absence of any obvious connection between the broadcast and the defendants, a mid-trial voir dire of the jury might well have prejudiced the defendants by drawing attention to the sentencing issues discussed in the broadcast before these defendants had even been found guilty. Accordingly, we conclude that the district court did not abuse its discretion when it denied appellant’s request for a mid-trial voir dire.
D. Equal Protection
Appellant Holton contends that minorities are denied the equal protection of the law because they are disproportionately impacted by the higher mandatory minimum sentences applied for crimes involving crack cocaine than for crimes involving powder cocaine. He notes that the United States Sentencing Commission and an article published in the Journal of the American Medical Association support the conclusion that there is no rational basis for treating crack cocaine differently than powder cocaine. See Dorothy K. Hatsukami and Marian W. Fischman, Crack Cocaine and Cocaine Hydrochloride: Are the Differences Myth or Reality?, 276 J. Am. Med. Ass’n 1580-88 (1996). He argues that “where a law has a grossly disproportionate impact on one racial group, and where there are strong indications that the disparity is the result of an irrational statutory distinction and discriminatory enforcement,” Holton Brief at 28, the Fifth Amendment right to equal protection of the law is violated.
In analysing whether the sentencing disparity denies constitutional equal protection, the first inquiry is whether the mandatory crack mínimums discriminate based on race. In order to prove that a facially neutral statute, such as the one involved here, violates equal protection guarantees, a challenger must demonstrate a racially discriminatory purpose behind the statute.
Washington v. Davis,
Here, appellant has not offered any specific evidence of disparate impact. Because he concentrates on the irrationality of the sentencing disparity, we surmise that his current argument is that since the Sentencing Commission and scientific analysis, such as that published in the Journal of the American Medical Association, indicate that crack cocainе and powder cocaine are not distinguishable, Congress should change the law and equalize the mandatory mínimums. The opinions of the Sentencing Commission and scientific journals do not provide the requisite proof that Congress was motivated by any impermissible considerations. Moreover, this circuit recently reaffirmed its conclusion that there is a race-neutral explanation for the sentencing disparity. “As evident from our analysis in
United States v. Cyrus
and
Thompson,
Congress acted in light of the distributional efficiencies, heightened potency and acute violence associated with crack cocaine. The crack/powder distinction in the statute is thus readily explained on grounds other than race.”
United States v. Johnson,
The convictions and sentences below are affirmed.
So ordered.
Notes
. Prior to introduction of the first tape, the district court instructed the jury:
[0]nly portions of the tape will be played. You will be provided with Exhibit 10C-1, which has been identified as а transcript. It has not been received into evidence. The transcript that you’ll be provided with is simply an aid to assist you in listening to the tape. And it is the tape which is in evidence. If you hear anything on the tape but do not see anything in the transcript, it's what you understand to be on the tape, which is actually in evidence.
A similar instruction was given prior to the distribution of each transcript. During its final instructions to the jury, the court charged: *1545 Transcripts of ... tape recordings, recorded conversations, were furnished for your convenience and guidance as you listened to the tapes to clarify portions of the tapes which are difficult to hear and to help you identify the speakers.
Tapes, however, as I told you, are evidence in the case; the transcripts are not evidence. If you perceived any variation betweеn the transcripts and the tapes as to the words spoken or the speakers, you must be guided solely by the tapes and not by the transcripts.
If you cannot determine from the tape that particular words were spoken, you must disregard the transcript insofar as those words are concerned.
. The court’s note to the jury explained:
As you will recall and is set forth on p. 19 of the instructions, which I ask you to review, the transcripts are not evidence, but are mere aids in listening to the tapes, with the tapes themselves having been received into evidence. Before each tape is played in its entirety, the transcripts of the portions played will be given to you, as before to assist you. After each tape has been played, the transcripts once again will be collected from you.
. Federal Rule of Criminal Procedure 43(a) provides that "[t]he defendant shall be present ... at every stage of the trial including the impaneling if the jury and the return of the verdict....”
