This appeal presents the questions, first, whether a reputation witness may testify to “negative evidence” of a defendant’s reputation, and second, whether the government may impeach a reputation witness by reference to the defendant’s juvenile arrests. We hold that negative evidence of reputation is admissible but that, in this case, the trial court’s exclusion of such testimony was harmless error. We also hold that the trial court properly allowed the government to test a witness’ knowledge of appellant’s reputation by asking whether the witness had heard that appellant had been arrested as a juvenile. We therefore affirm appellant’s convictions.
I.
Appellant was convicted of distribution of phencyclidine (PCP) and cannabis (marijuana), D.C. Code § 33-541(a)(l) (1981 Supp.). At trial, the government presented testimony to the following effect: Appellant had approached an undercover police officer and asked her whether she was looking for some “herb” (meaning marijuana). The officer replied no, but said that she was looking for some “boat” (meaning PCP). Appellant walked across the street to another person, appeared to receive something from that person, and returned to the officer. The officer then gave appellant twenty-seven dollars in prerecorded police funds in exchange for two tinfoil packets containing PCP and marijuana. The officer broadcast a description of the seller, and an arrest team, on the basis of that description, arrested appellant a short time later. About twenty minutes after the sale, the purchasing officer returned to the scene and identified appellant as the man who had sold her the drugs. Appellant had no money in his possession at the time of his arrest.
Appellant, testifying in his own behalf, denied that he had sold any PCP. Rather, he testified, on the date of his arrest he had walked to a local boys club to find a friend with whom he had planned to play basketball. He stopped to talk with several other acquaintances but, not finding Abbott, left the club and went to look for him. Appellant testified that as he was walking down the street, a policeman detained him. Several other witnesses, including Abbott, corroborated appellant’s testimony.
*930The jury found appellant guilty of distribution of phencyclidine and cannabis. This appeal followed.
II.
Appellant first challenges the court’s exclusion of testimony by Reverend David Durham, the minister of appellant’s church, whom the defense had called to testify about appellant’s reputation in the community for truth and veracity.
Defense counsel, attempting to lay a foundation for the witness’ reputation testimony, asked Rev. Durham, “Have you heard anything spoken about the defendant and his reputation as to truth and veracity?” Rev. Durham answered, “No, I haven’t.” The government moved to strike the minister’s testimony, arguing that he was not qualified to testify because his knowledge of appellant’s “community” was limited to his church congregation, and not to the community in which appellant lived. The court granted the motion to strike not on the objected-to ground, but because appellant had not established that the witness had “actually spoken to members of the community.”
Following a recess and discussion of some other matters, defense counsel asked the court’s permission to recall Rev. Durham. Counsel argued that, since the minister was “in a position to have heard about” appellant’s reputation, he should be allowed to testify that he had heard nothing negative about the defendant. The trial court, while not ruling immediately, eventually denied appellant’s request and ruled that reputation testimony was permissible only if the witness had specifically discussed the defendant’s reputation with other members of the community.
We agree with appellant that the trial court’s ruling was error. If a witness is in such a position that he or she probably would have heard discussions in the community concerning the defendant's reputation, the witness’ failure to have heard anything negative about the defendant is probative of a favorable reputation.1 As the Supreme Court stated in Michelson v. United States, 335 U.S. 469, 69 S.Ct. 213, 93 L.Ed. 168 (1948),
[T]he [reputation] witness must qualify to give an opinion by showing such acquaintance with the defendant, the community in which he has lived and the circles in which he has moved, as to speak with authority of the terms in which generally he is regarded. To require affirmative knowledge of the reputation may seem inconsistent with the latitude given to the witness to testify when all he can say of the reputation is that he has “heard nothing against defendant.” This is permitted upon assumption that, if no ill is reported of one, his reputation must be good.
Id. 335 U.S. at 478 69 S.Ct. at 219 (emphasis added) (footnotes omitted). While this question has never been addressed directly in this jurisdiction,2 the rule allowing testi*931mony by a reputation witness that he or she has heard nothing bad about a defendant, although the witness was in a position to have heard such statements, is well established in other jurisdictions. See, e.g., State v. Huffman, 607 S.W.2d 702, 704 (Mo.Ct.App.1980); Baldwin v. State, 538 S.W.2d 109, 113 (Tex.Crim.App.1976); Lowery v. State, 39 Ala.App. 659, -, 107 So.2d 366, 367 (1958): State v. Gambutti, 36 N.J.Super. 219, 232, 115 A.2d 136, 143 (1955): cf. Wisniewski v. State, 51 Del. 84, 94, 138 A.2d 333, 339 (1957) (witness who is well acquainted with person may testify to his or her reputation, even if witness never heard that reputation discussed). We join those jurisdictions in adopting this rule.
Although testimony as to a lack of bad reputation is thus admissible under appropriate circumstances, it is incumbent upon the trial court to assure that the absence of notoriety reflects the community’s esteem rather than the witness’ ignorance. Thus, negative evidence of reputation “is accepted only from a witness whose knowledge of defendant’s habitat and surroundings is intimate enough so that his failure to hear of any relevant ill repute is an assurance that no ugly rumors were about.” Michelson, supra, 335 U.S. at 478, 69 S.Ct. at 220. In the instant case, however, the exclusion of Rev. Durham’s testimony was based on the court’s erroneous assumption that negative evidence of reputation was improper under any circumstances, rather than on a determination that Rev. Durham was not in a position to know of appellant’s reputation. We therefore hold that the trial court abused its discretion in striking Rev. Durham’s testimony, and in refusing to allow appellant to recall him. See Johnson v. United States, 398 A.2d 354, 363 (D.C.1979) (failure to recognize need to exercise discretion constitutes abuse of discretion).
Without deciding whether the trial court’s error was of constitutional magnitude, cf. Bassil v. United States, 517 A.2d 714, 716-17 (D.C.1986) (error of constitutional dimension to deny defense right to call witness to testify concerning government witness’ bad reputation for truthfulness), we nevertheless conclude that, under either a non-constititutional harmlessness test, see Kotteakos v. United States, 328 U.S. 750, 765, 66 S.Ct. 1239, 1248, 90 L.Ed. 1557 (1946), or under the more stringent “harmless beyond a reasonable doubt” test, see Chapman v. California, 386 U.S. 18, 24, 87 S.Ct. 824, 828, 17 L.Ed.2d 705 (1967), the trial court’s exclusion of Rev. Durham’s testimony could not have prejudiced appellant. Even assuming that proper inquiry would have revealed that Rev. Durham was sufficiently intimate with appellant’s surroundings, his testimony would have been merely cumulative of the more concrete testimony of appellant’s second reputation witness, who testified that she had heard people speak about appellant and that his reputation was “[t]hat he tells the truth.” Furthermore, as discussed infra, if Rev. Durham had been allowed to testify, the government would have been permitted to probe his knowledge of appellant’s reputation by inquiring whether he knew that appellant had been arrested as a juvenile. Because we are convinced that Rev. Durham’s testimony could not have affected the jury’s verdict, we need not remand the question of whether he was in a position to have known if appellant had had a bad reputation for truth and veracity.
III.
Appellant next challenges the trial court’s ruling that the prosecutor could ask appellant’s reputation witness whether she had heard about appellant’s juvenile arrests.
Before the defense began to present its case, the prosecutor inquired as to whether he could use appellant’s record of juvenile arrests to impeach defense witnesses who would testify about appellant’s reputation for truth and veracity. In the course of a colloquy among the prosecutor, defense *932counsel, and trial judge, it was revealed that, of the three arrests that the prosecutor wished to raise, two had been dismissed and one had resulted in a consent decree.3 Initially, based on the respective outcomes of the arrests, the trial court ruled that the potential prejudice of allowing questions about them outweighed any probative value. Later, however, the court reversed its ruling and allowed the prosecutor to ask appellant’s reputation witness about the arrests. The witness answered that she had not heard about the arrests. The court immediately instructed the jury that the questions were “not intended to establish that those events took place, but only to attest the reliability of the character [witnesses testimony.”
This court has recently addressed the propriety both of asking reputation witnesses about a defendant’s juvenile adjudications, and of asking about “bad acts” underlying such adjudications. We ruled that, while inquiry into “bad acts” is permissible, inquiry into adjudication is not. See Devore v. United States, 530 A.2d 1173, 1175 (D.C.1987); McAdoo v. United States, 515 A.2d 412, 418 (D.C.1986). In McAdoo, we reasoned that questions about a defendant’s juvenile adjudications have no legitimate probative value because the confidentiality that attaches to juvenile records makes it unlikely that a witness will have heard talk about the adjudications. Id. at 419; cf. D.C.Code § 16-2331 (1981) (confidentiality of juvenile case records). We added that such questions are highly prejudicial, in part because they “plant[ ] an impression which the character witness is not in a position to counteract.” Id. Finally, we noted, questions about juvenile adjudications have the negative effect of disclosing records for which there is a strong policy of confidentiality. See id.
In Devore, on the other hand, we distinguished McAdoo and held that the government may question a reputation witness about wrongful acts committed by the defendant as a juvenile. In contrast to their probable lack of awareness of juvenile adjudications, “it seems reasonably likely ... that community members in general will have heard of a juvenile’s commission of wrongful acts, independently of any arrest or adjudication.” 530 A.2d at 1175 (emphasis added) (footnote omitted). Since wrongful acts were within the realm of community knowledge, we concluded, McA-doo’s blanket prohibition against questions about juvenile adjudications should not apply to bar questions about the acts underlying those adjudications. Id. Our resolution of the issue at hand turns upon our response to a question left open by Devore: whether community members are likely to have heard of juvenile arrests, as they are of wrongful acts, independently of the resulting confidential adjudication. We answer that question in the affirmative.
An arrest is usually a public act. The community’s knowledge of an arrest does not depend on its access to police records, cf. D.C.Code § 16-2333 (1981); to hearings, cf. D.C.Code § 16-2316(e) (1981); or to their consummation as a judicial decision, cf. D.C.Code § 16-2331 (1981). No knowledge obtained from juvenile records is involved. Rather, the fact of an arrest is knowledge accessible to any bystander who happens to view the arrest in progress.4 *933What is known to the bystander soon becomes known to the community, and indeed, in the case of arrests, is likely to become a point of focus in the community’s gaze.
We conclude that, when a defendant has chosen to place his character in issue by presenting a witness to testify about his reputation, fairness demands that the prosecution have the opportunity to challenge the witness’ statements, both as to the depth of the witness’ knowledge of events within the community’s consciousness, and as to the accuracy of the witness’ representations.5 Having initiated inquiry into the view of his community, an inquiry the government could not itself make part of the trial, the defendant may not enshroud a history of arrests that are likely to have affected that community’s view. As we stated in Devore, when a defendant “by introducing a character witness ... elects to prove his good name, he draws aside by his own hand whatever veil the law may otherwise place over his youthful conduct....” 530 A.2d at 1176.
Again, as we stressed in Devore, the trial court must “carefully weigh the probative value and prejudicial effect” of exposing the juvenile arrests before deciding whether to permit the prosecutor’s inquiry. See id.6 In the instant case, it is clear that the trial court considered the potential prejudice to appellant and concluded that any such prejudice was outweighed by the need to test the basis for the witness’ testimony about appellant’s reputation. We hold that the court did not abuse its discretion in permitting the impeachment.
In sum, we agree with appellant that the trial court abused its discretion when it excluded negative testimony about appellant’s reputation; we hold, however, that the error was harmless. We also hold that the trial court properly exercised its discretion when it permitted the prosecutor to ask a reputation witness about appellant’s juvenile arrests. Appellant’s convictions are therefore
Affirmed.
. The opinion in State v. Baldanzo, 106 NJ.L. 498,148 A. 725 (N.J.1930), makes the point most eloquently:
[I]t is the unusual, the abnormal, the nonconforming act that provokes talk. To behave one’s self, to live decently, is to be, in those respects, normal and conventional.... There is little therein to start tongues wagging. When one departs from the conventional and does that which the majority of people do not do, then talk begins.... It does not follow, however, that a man who leads a life that, according to the standards of the neighborhood, is usual and correct and who, therefore, has not given his neighbors food for chat, holds no place in the esteem of the community. On the contrary, he may be highly regarded. The very absence of talk is an indication that the neighborhood regards him as worthy. ... Shall then the man whose life has met the community thought as to how a person should live, and who consequently has not been talked about, be deprived of the privilege of proving this reputation when the hour of need arrives and when it may be of vital importance to him to show what the community estimate of him is? In all fairness that should not be and, according to the weight of authority, is not so.
Id. at 501, 148 A. at 727.
. Fletcher v. United States, 42 App.D.C. 53 (1914), held that it was proper to strike testimony by a reputation witness who testified that a government witness had a bad reputation for truth and veracity, when the reputation witness had never discussed with anyone nor heard discussed the government witness’ reputation. Id. at 66-67. In Fletcher, however, the reputation witness candidly admitted that his state*931ment that the government witness’ reputation "was bad” was based only on his own behalf, and not the opinion of others. Id. at 66. Furthermore, we think it obvious that while lack of community discussion may reflect a person’s good reputation, it is not probative of a person’s bad reputation. See Gilson v. State, 140 Tex. Crim. 345, 346, 145 S.W.2d 182, 183 (1940).
. We note that appellant's records had not been sealed under D.C.Code § 16-2335 (1981).
. The government’s ability in general to question a reputation witness about the defendant's (non-juvenile) arrests is clear:
Arrest without more may nevertheless impair or cloud one’s reputation. False arrest may do that. Even to be acquitted may damage one's good name if the community receives the verdict with a wink and chooses to remember defendant as one who ought to have been convicted....
The inquiry as to an arrest is permissible also because the prosecution has a right to test the qualifications of the witness to bespeak the community opinion. If one never heard the speculations and rumors in which even one’s Mends indulge upon his arrest, the jury may doubt whether he is capable of giving any very reliable conclusions as to his reputation.
Michelson, supra, 335 U.S. at 482-83, 69 S.Ct. at 221-22. We held recently in Crews v. United States, 514 A.2d 432 (D.C.1986) that a defendant’s arrests could be used to cross-examine a character witness he called to testify as to his truth and veracity.
. While cases dealing specifically with impeachment of a reputation witness by reference to the defendant's juvenile arrests appear to be few, those that we have found all allow such impeachment. See Green v. State, 352 So.2d 1149, 1151 (Ala.Crim.App.1977); Love v. State, 533 S.W.2d 6, 10 (Tex.Crim.App.1976); State v. Knight, 323 So.2d 765, 768 (La.1975); Hendron v. Commonwealth, 487 S.W.2d 275, 278 (Ky. 1972). See also Commonwealth v. Jenkins, 413 Pa. 606, 198 A.2d 497 (1964), in which the Pennsylvania Supreme Court reversed the defendant’s conviction because of errors in cross-examining a reputation witness about the defendant’s juvenile arrests. The court’s basis for finding error, however, appears to have been the form of the prosecutor’s question, rather than the fact that the arrests occurred when the defendant was a juvenile. See id. at 607, 198 A.2d at 498. This interpretation is borne out by a more recent Pennsylvania decision, in which the court summarily rejected the appellant’s argument that the trial court had erred in allowing impeachment of a reputation witness by reference to juvenile arrests. See Commonwealth v. Floyd, 494 Pa. 537, 550 n. 7, 431 A.2d 984, 992 n. 7 (1981).
. In aid of its exercise of discretion, the court may choose to ascertain whether the arrest was accomplished out of public view or otherwise in such a way that the community probably was unaware of it. The defense, of course, may offer information to this effect in opposing such cross-examination.
