    Before GLICKMAN and EASTERLY, Associate Judges, and PRYOR, Senior
    Judge.
    2
    EASTERLY, Associate Judge: Carl Morton and Alonzo Vaughn appeal their
    convictions for aggravated assault (D.C. Code § 22-404.01 (2012 Repl.)) and
    assault on a law enforcement officer (D.C. Code § 22-405 (c) (2012 Repl.)). Both
    were charged in connection with an incident at the D.C. Jail in which a group of
    men attacked a fellow inmate, Deon Spencer, and a corrections officer who came
    to that inmate‟s aid, Sergeant Charles White. The victims could not identify Mr.
    Morton and Mr. Vaughn; but the incident was recorded by multiple cameras, and,
    although these recordings were not exactly movie-quality, two corrections officers
    said they could identify Mr. Morton and Mr. Vaughn in the footage.             The
    government presented the testimony of these corrections officers in conjunction
    with the recordings to the jury, and the jury convicted. But unbeknownst to the
    defendants, one of these identifying witnesses, introduced by the government as
    “Officer” Angelo Childs, had a significant credibility issue.
    Six months earlier, Officer Childs had filed reports accusing a different
    inmate (“Inmate A”) of assault, thereby providing a potential justification for his
    use of a chemical agent on the inmate. His accusations were investigated by the
    Department of Corrections (DOC) Office of Internal Affairs (OIA). The DOC
    OIA determined in a “Final Report,” that, among other things, video footage of this
    incident did not show the alleged inmate assault.
    3
    The OIA Officer who wrote the OIA Final Report about the Inmate A
    incident stated in a sworn affidavit (submitted by the government during post-trial
    proceedings in this case) that he sent the OIA Final Report to the DOC Office of
    the Director, the entity in charge of disciplinary action, and he was later informed
    that the DOC Office of the Director demoted Officer Childs from Lieutenant to
    Sergeant after it received the report. In addition, this OIA Officer, who also
    assisted the government in the investigation of the Spencer-White attacks, stated in
    his affidavit that he “notified the U.S. Attorney‟s Office for the District of
    Columbia of the Investigative Report concerning Lieutenant Childs and his
    subsequent demotion” on September 15, 2009, approximately two months before
    Mr. Vaughn and Mr. Morton‟s trial.
    The government did not disclose this favorable impeaching information to
    the defense. Instead, a week before trial, the government filed a motion in limine
    to preclude the defense from questioning Officer Childs about the misconduct
    detailed in the OIA Final Report. In that motion, the government provided a
    “summary” of the OIA Final Report that gave no indication that the OIA had
    investigated a potentially false allegation of an inmate assault by Officer Childs
    and others and determined that this allegation was false; the government also did
    not reveal Officer Childs‟s resulting demotion. Rather, the government‟s summary
    4
    focused exclusively on only a portion of the OIA Final Report that considered
    whether Officer Childs (1) had properly used a chemical agent on the accused
    inmate, who the government (quoting the very portion of Officer Childs‟s Incident
    Report the OIA had discredited) indicated had been acting aggressively, and (2)
    had falsely indicated in a report that the inmate was unrestrained. Portraying this
    investigation with skepticism, the government argued that it had little to do with
    Officer Childs‟s credibility because the OIA had determined Officer Childs had
    only “suggest[ed]” that the inmate was unrestrained.
    The difference between the government‟s summary of the OIA investigation
    and the actual OIA Final Report almost certainly would have come to light had the
    government provided the trial court with the full copy. It did not. Along with its
    summary, the government submitted to the trial court ex parte what it said was the
    OIA Final Report, but in fact was only the first five pages of the ten-page report
    (and included none of the documents in the appendix, 76 pages in all). The first
    five pages of the OIA Final Report contain “background” information,
    investigative notes, and a full reproduction of Officer Childs‟s account of an
    inmate assault in his Incident Report without any indication that that account was
    being questioned; the findings adverse to Officer Childs begin on the sixth page.
    5
    Under Brady v. Maryland, 
    373 U.S. 83
    (1963), the government has a
    constitutionally mandated obligation to disclose to the defense, prior to trial,
    information in the government‟s actual or constructive possession that is favorable
    and material. The government did not fulfill its due process disclosure obligations
    in this case. Moreover, its failure to provide the court and the defense with
    complete and accurate information as to the contents of the OIA Final Report
    thwarted the trial court‟s ability to “require strict compliance with the demands of
    Brady . . . in the first instance.” Boyd v. United States, 
    908 A.2d 39
    , 62 (D.C.
    2006). As to Mr. Morton, we reverse his two convictions on this ground and
    remand for a new trial after the government has certified in writing that it has
    fulfilled its duty to learn of and disclose all the favorable information in the
    possession of the United States Attorney‟s Office and the entire the prosecution
    team. As for Mr. Vaughn, we determine that a jury instruction conceded to be
    erroneous by the government requires reversal of his conviction for aggravated
    assault. We reject the remaining claims raised by Mr. Morton and Mr. Vaughn.
    I.    The Spencer-White Attacks, the DOC Investigation, and Mr. Morton
    and Mr. Vaughn’s Trial
    Mr. Morton and Mr. Vaughn were prosecuted for their alleged involvement
    in an attack at the D.C. Jail on a corrections officer, Charles White, but it all began
    6
    with an attack on a fellow inmate, Deon Spencer.1 On December 27, 2007, Mr.
    Spencer was in the communal dining area of the Southwest 2 (“SW2”) housing
    unit when an inmate began hitting and kicking him. Corporal James Weathers, a
    corrections officer on duty in SW2, tried to assist Mr. Spencer, but he was
    outnumbered by the many inmates who rushed into the area and joined in the
    attack. Corporal Weathers radioed for help, and “that‟s when everything just broke
    apart.” He described the scene as a “melee.”
    Sergeant White, assigned to the Southeast 2 housing unit, responded to
    Corporal Weathers‟s call for help. As he tried to quell the disturbance, he was
    attacked.   Sergeant White was initially pushed onto a dining table, but he
    immediately got back up and moved away from the table. At some point, Sergeant
    White ended up on the floor. Several inmates then kicked him about the head and
    body and knocked him unconscious. As he lay in the walkway, inmates ran back
    and forth through the area, over and around his body.
    1
    Bobby Johnson and Lorenzo Woods, Mr. Morton and Mr. Vaughn‟s co-
    defendants at trial, were among those charged with the attack on Mr. Spencer. Mr.
    Woods was acquitted; Mr. Johnson is not a party to this appeal.
    7
    In the meantime, a number of other corrections officers responded to the
    scene.2 The incident ended when a chemical agent was dispersed, forcing inmates
    back into their cells. SW2 went on lockdown.
    Mr. Morton and Mr. Vaughn were not initially identified as participants in
    the attack. The victims, Mr. Spencer and Sergeant White, were unable to identify
    their assailants from the 156 inmates housed on SW2 on the day of the attack. The
    officers who had seen and responded to the attack wrote Incident Reports
    immediately after the incident identifying a number of inmates they had seen
    participating in the violence—many of whom were charged and eventually pled
    guilty in connection with this incident.3 Mr. Morton and Mr. Vaughn were not
    among these individuals.
    2
    Sergeant Jimmy Harper, the senior officer on duty, succeeded in
    restraining one inmate, but could not recall if he returned to the fray thereafter.
    Officer Tamira Robeson, who was working her first day on the unit and was
    assigned to the “bubble,” the control module for the unit, remained at her post.

    OIA Investigator Benjamin Collins, who led the DOC investigation into this
    incident, sought to identify additional individuals involved in the attacks using
    recordings of the incident from fixed cameras capturing images of SW2 from
    different angles. The recordings were of limited utility on their own, however. In
    particular, the footage of the attack on Sergeant White is of extremely poor quality.
    Instead of a seamless “moving picture,” it is a choppy series of still images,
    capturing a chaotic sequence of events only at regular intervals. In addition, the
    images are highly pixelated and the faces are, as DOC staff conceded, “blurry.”4
    Accordingly, the DOC set out to find corrections officers who could identify
    individuals in the recorded footage.
    The morning after the attacks, OIA Investigator Collins met with Officer
    Childs.5 Officer Childs had not been on duty the day prior but he had already
    watched some footage of the incident with Officer Harper. Officer Childs told
    4
    The vast majority of the inmates seen in the recordings are young African-
    American males within a range of average height and build. With the exception of
    one inmate dressed all in white, these inmates were wearing the DOC standard-
    issue one-piece orange jumpsuit. Presumably to facilitate identification, the
    inmates‟ jumpsuits bear armbands with an inmate‟s name and a number assigned
    to the individual inmate, but this identifying information is not visible in the
    videotapes.
    5
    Although his precise rank proved to be a matter of some significance, the
    government generically introduced Mr. Childs as “Officer” at trial and for
    consistency‟s sake we follow suit.
    9
    OIA Investigator Collins that “he was very familiar with the vast majority of the
    inmates in the unit and that he . . . had named at least 11 inmates who he saw in the
    video that were involved in the altercation.” Apparently he then identified Mr.
    Morton as a participant in the attack on Sergeant White. Several months later OIA
    Investigator Collins brought Officer Childs to the U.S. Attorney‟s Office, at which
    point Officer Childs identified Mr. Vaughn as another participant in this attack.
    OIA Investigator Collins also spoke to Sergeant Harper in the course of his
    investigation. Sergeant Harper ultimately identified Mr. Morton and Mr. Vaughn
    as participants in the attack on Sergeant White as well.
    Beyond Officer Childs‟s and Sergeant Harper‟s identifications of
    participants from the video footage, the record does not reflect that the government
    developed any other evidence against Mr. Morton and Mr. Vaughn. Mr. Morton
    and Mr. Vaughn were each indicted in November 2008 for their alleged
    involvement in the attack on Sergeant White.
    Mr. Morton and Mr. Vaughn went to trial a year later, in November 2009.
    The government argued that Mr. Vaughn was the only inmate dressed all in white
    and that he had given Sergeant White “one good shove.” The government argued
    that Mr. Morton was one of the inmates who kicked Sergeant White as he lay on
    10
    the floor. In support of these theories, the government presented Officer Childs‟s
    testimony. Explaining his ability to identify Mr. Morton and Mr. Vaughn as
    participants in the attack on Sergeant White, Officer Childs testified that he had
    been working on the unit for over a year, that Mr. Morton and Mr. Vaughn had
    each been on the unit for several months, that he knew them and their facial and
    physical features well, and that he could clearly see them in the video footage and
    in multiple stills taken from the video footage. Although defense counsel was able
    to highlight minor inconsistencies in Officer Childs‟s testimony on cross-
    examination, Officer Childs‟s testimony was largely unimpeached.
    Sergeant Harper testified after Officer Childs. He could only identify Mr.
    Morton at one point in the recorded footage of the attack on Sergeant White and
    only recognized Mr. Morton in one of several video stills of that attack.6 Sergeant
    Harper was impeached with the fact that, despite his claim at trial that he “kn[ew]
    on December 27 that all of [the individuals he identified at trial] were involved,”
    6
    Even though Mr. Morton and Mr. Vaughn were not charged with any
    crime in connection with the attacks on Mr. Spencer, Sergeant Harper initially
    identified them as participants in the attack on Mr. Spencer. The government did
    not ask Sergeant Harper to identify Mr. Morton or Mr. Vaughn in the footage of
    that attack.
    11
    he had not named Mr. Morton or Mr. Vaughn in his initial Incident Report written
    December 27.
    In closing, the government made clear that its case turned on the jury‟s
    assessment of the credibility of the DOC officers who had testified and had
    identified the defendants. The government began by asking the jury “to consider
    all of the evidence”: “[t]he video, the documents[,] and importantly the testimony
    that you heard from the Corrections Officers.” The government informed the jury
    that its ultimate task was “to assess the credibility of those officers when they were
    on the stand. That‟s what you‟re asked to do here today.” Specifically addressing
    the identifications made by Officer Childs and Sergeant Harper, the government
    returned to the theme of credibility: “[P]art of your job in this case is to assess the
    credibility of these officers on the stand. . . . Angelo Childs told you repeatedly and
    strongly . . . [t]hat is Alonzo Vaughn and that is Carl Morton. Jimmy Harper, same
    thing.” And the government concluded by “emphasiz[ing] again, this case is . . .
    about your credibility judgments.” It was a winning argument. Even if the jury
    was not convinced by Sergeant Harper‟s somewhat inconsistent and weak
    testimony, it had little or no reason to doubt the testimony of Officer Childs.
    12
    II.   The Brady Claim
    Mr. Morton and Mr. Vaughn both argue that there were reasons to doubt
    Officer Childs‟s credibility, but that the government did not timely or accurately
    apprise the defense of this information. We return to the facts on record.
    A. The Pertinent Facts
    1. The OIA Final Report
    The following facts are taken from the OIA Final Report. In the spring of
    2009 (as the parties prepared for trial in Mr. Morton and Mr. Vaughn‟s case),
    Officer Childs participated in a mission to eliminate contraband at the D.C. Jail.
    Officer Childs, at that time a lieutenant, was a supervising officer on the Search
    and Recovery Team (SRT), along with Major Nora Talley and Lieutenant Gregory
    McKnight. Sergeant David Thomas and his drug-sniffing dog, “Reggie,” also
    assisted with the search for contraband.
    13
    In the course of this contraband recovery mission, Inmate A7 and his cell
    were searched by members of the SRT. Specifically, Inmate A was strip searched
    in his cell and then restrained and taken by Lieutenant McKnight to the Body
    Orifice Security Scanner (BOSS Chair);8 meanwhile the drug-sniffing dog
    inspected Inmate A‟s cell. Both before and after his trip to the BOSS Chair,
    Inmate A told Lieutenant McKnight that he was scared of dogs and of the drug-
    sniffing dog in particular.
    Once Inmate A returned from the BOSS Chair, Lieutenant McKnight left
    him, still in restraints, standing near the bubble in the presence of Officer Childs
    and Major Talley. At this point, Inmate A “stated emphatically that he would not
    go anywhere near the canine.” Although the protocol for the contraband recovery
    mission did not include using the drug-sniffing dog to inspect inmates, Officer
    Childs grabbed Inmate A‟s arm and signaled to Officer Thomas to bring the dog
    over to Inmate A. As the dog approached, Inmate A tried to back away but Officer
    Childs “halted his movement.” Inmate A “stomped his foot in the direction of the
    canine”; Officer Childs “responded by placing his container of chemical agent near
    7
    We retain the trial court‟s and parties‟ convention of calling this individual
    “Inmate A.”
    8

    14
    [Inmate A‟s] face.” Sergeant Thomas then “positioned” the dog behind [Inmate A]
    and “placed his right hand against the lower calves and then on the lower back of
    [Inmate A].” The dog “followed with his muzzle where Sergeant Thomas placed
    his hand.” The dog “stood up on his hind legs and attempted to rest his paws on
    [Inmate A‟s] back.” Inmate A recoiled from this contact, but “his movement was
    impeded when Lieutenant Childs, who maintained physical control of [Inmate A],
    sprayed a single burst of chemical agent directly into [Inmate A‟s] face.”
    That same day, Officer Childs prepared an Incident Report explaining the
    reason for his use of force and a Disciplinary Report accusing Inmate A of “Lack
    of Cooperation [and] assault without serious injury.” In both reports, Officer
    Childs asserted that Inmate A had “refuse[d] to be search[ed] by the [dog]” and
    had “started kicking at” the drug-sniffing dog and that Officer Childs had sprayed
    the chemical agent in Inmate A‟s face to “seize [sic] his disruptive behavior.”
    Officer Childs then stated in the Incident Report that Inmate A was “placed in
    restraints” and escorted out of the unit, thereby effectively stating that Inmate A
    had previously been unrestrained. Officer Childs concluded his Incident Report
    with the assertion that “[t]his incident stemmed from the violent/disruptive
    behavior of [Inmate A].” Major Talley and Sergeant Thomas also filed reports in
    which they told a similar narrative of Inmate A‟s unprovoked, aggressive behavior.
    15
    According to the OIA Final Report, video footage contradicted all of these
    reports. Four days after this incident, at the request of the Director of the DOC, the
    OIA opened a formal investigation. The lead investigator was Benjamin Collins,
    the same OIA investigator who had led the inquiry into the Spencer-White attacks
    and had brought Officer Childs to the U.S. Attorney‟s Office so that he could serve
    as a witness. After OIA Investigator Collins completed his investigation, the OIA
    issued the Final Report on June 27, 2009.
    The OIA Final Report is ten pages long and includes appendices totaling 76
    pages.9   The first five pages of the OIA Final Report contain “background”
    information, investigative notes, and a full reproduction of Officer Childs‟s
    account, in his Incident Report, that Inmate A had tried to thwart a legitimate
    search for contraband and acted with unprovoked aggression.             The findings
    adverse to Officer Childs and his colleagues do not begin until page six. At that
    9
    The appendices include Officer Childs‟s Incident Report explaining his
    use of a chemical agent and his Disciplinary Investigative Report formally
    accusing Inmate A of “assault without serious injury”; it also includes reports from
    Major Talley, Sergeant Thomas, and Lieutenant McKnight, a “Letter of Direction”
    from Major Talley to Officer Childs, see infra note 10, and three DOC Program
    Statements addressing (1) use of force and application of restraints, (2) the policies
    of the canine unit, and (3) the Employee Code of Ethics and Conduct.
    16
    point, the OIA memorialized its determination that Inmate A had not—as Officer
    Childs had claimed—engaged in “disruptive behavior” necessitating use of force.
    Specifically, the report states that “[v]ideo footage of the incident does not support
    the allegation that [Inmate A] assaulted any Correctional Officer or canine.” On
    subsequent pages, the report reviewed and then similarly discredited the stories
    told by Sergeant Thomas and Major Talley. With respect to Major Talley‟s report,
    the OIA determined that “[v]ideo footage. . . does not depict any malicious
    aggressive behavior towards the canine or any staff member by [the] inmate. . . ,
    and therefore contradicts Major Talley‟s written account.”          With respect to
    Sergeant Thomas, the OIA likewise determined that notwithstanding his assertions
    that Inmate A “kick[ed] at” the dog, “video footage capturing this occurrence on
    the tier shows no contact or direct interaction between [Inmate A] and canine
    Reggie.”
    The OIA Final Report further notes that, although Officer Childs‟s
    “narrative suggests that at the time of the incident, [Inmate A] was not restrained,”
    “[u]pon review of the facts and circumstances of this incident, it is evident that
    [Inmate A] was in restraints and not a threat to „normal operations‟ when he was
    sprayed with chemical agent by Lieutenant Childs.” In other words, the OIA
    determined that, to the extent the false story of an inmate assault was meant to
    17
    justify the use of a chemical agent to subdue Inmate A, it failed not only because it
    was false, but also because it did not account for the fact that Inmate A was already
    restrained.10
    The OIA Final Report concludes with four summary “Findings” reiterating
    that Officer Childs “us[ed] . . . a chemical agent on a restrained inmate who posed
    no immediate danger to himself or others” thereby violating the DOC “use of force
    continuum”; that he “submitted a false and or misleading Incident Report of the
    facts in stating that the inmate was placed in restraints after being sprayed with
    chemical agent” and that Major Talley and Sergeant Thomas had also filed “false
    and[/]or misleading” Incident Reports asserting that Inmate A had attempted to
    kick the drug sniffing dog and tried to “fight” Officer Childs.11
    10
    The OIA Final Report acknowledges that Major Talley issued Officer
    Childs a Letter of Direction reprimanding him for “Neglect of Duty and
    Incompetence” in connection with his use of a chemical agent on Inmate A when
    Inmate A was “restrained from the rear, and posed no immediate threat.” But the
    OIA Final Report indicates that this Letter of Direction was deficient because
    Major Talley, who herself had submitted a report recounting Inmate A‟s alleged
    aggression, “did not [c]ite Lieutenant Childs for submitting a false and[/]or
    misleading Incident Report.” Instead she, like Officer Childs, adopted the
    narrative that Inmate A had been “combative.”
    11
    Although these “Findings” highlight that Officer Childs “submitted a
    false and[/]or misleading Incident Report” in relation to whether Inmate A was
    restrained at the time Officer Childs sprayed him in the face with a chemical agent,
    the body of the report as a whole makes clear that all three officers told a similar
    (continued…)
    18
    The OIA merely conducts investigations; it does not recommend disciplinary
    action. Thus, according to the affidavit by OIA Investigator Collins later filed in
    this case by the government, see infra p. 25, after the OIA Final Report was
    completed, he sent it to the DOC‟s Office of the Director. Again according to
    Investigator Collins‟s affidavit, the Office of the Director of the DOC issued to
    Officer Childs “formal and written notification” on August 26, 2009, that he had
    been demoted from Lieutenant to Sergeant.             It was Investigator Collins‟s
    understanding that Officer Childs had signed this notice,12 and that Officer Childs‟s
    demotion became effective September 13, 2009. OIA Investigator Collins stated in
    his affidavit that “[o]n September 15, 2009, [he] notified the U.S. Attorney‟s
    (…continued)
    story about Inmate A acting aggressively and assaulting Officer Childs and the dog
    that the OIA determined was untrue.
    12
    Discipline of DOC employees is governed by the Comprehensive Merit
    Personnel Act, D.C. Code §§ 1-616.51 to -.54 (2012 Repl.). Implementing
    regulations require the agency to give such notice and the employee to
    acknowledge it. See 6-B DCMR § 1601.1 (2008) (covered employees may not be
    subject to discipline, including “reduc[tions] in grade” “except as provided in this
    chapter”); 6-B DCMR § 1614.1 (2004) (“employee shall be given a notice of final
    decision in writing . . . informing him . . . of the reasons” for corrective or adverse
    action); 6-B DCMR § 1614.4 (2004) (notice shall be delivered to employee “on or

    2. The Government’s Nondisclosure
    The government did not turn over the OIA Final Report to the defense prior
    to the November 2009 trial, nor did it disclose to the defense that it had
    information Officer Childs had been demoted by DOC in connection with the
    incident with Inmate A.       Instead, less than a week before trial began, the
    government, represented by the two Assistant United States Attorneys who
    prosecuted the case, filed (1) a motion in limine to prevent the defense from cross-
    examining Officer Childs on any issue related to the OIA Final Report, and (2) an
    accompanying ex parte motion requesting that (a) the court review in camera the
    first five pages of the ten-page report (“the five-page ex parte submission”), and
    (b) the court permit the government to file this attachment under seal.            The
    government did not inform the court that the five-page ex parte submission was not
    the complete OIA Final Report or that it was missing its appendices.13

    To a reader unfamiliar with the full report, it is not obvious that the five-
    page excerpt is incomplete. No text is cut off mid-sentence; rather, the bottom of
    the fifth page reaches what might be considered a stopping point after reproducing
    Officer Childs‟s account of Inmate A‟s alleged assault from his Incident Report.
    20
    The government‟s stated goal in filing its motion in limine was “to preclude
    the defense from referring to the fact DOC Office of Internal Affairs may have
    made potentially adverse credibility findings” against Officer Childs.        The
    government told the court and the defense that the OIA “investigation resulted in
    two findings related to Officer Childs: (1) Officer Childs‟ use of force violated
    DOC policy and (2) Officer Childs submitted a false or misleading statement in
    reciting the facts,” specifically, that “DOC Internal Affairs found that Officer
    Childs‟ statement that Inmate A was placed in handcuffs after being sprayed with a
    chemical agent was false or misleading.” The government pushed back against the
    second of these “two findings” and refused to “conced[e],” that Officer Childs “in
    fact made a false and/or misleading statement.”
    To support this position, the government provided the court and the defense
    with a “summary of an incident . . . in which DOC Internal Affairs issued a Final
    Report.” This summary, however, did not mention that the OIA had determined
    that Officer Childs and his fellow corrections officers had falsely accused Inmate
    A of assault. Instead the government‟s summary indicated that Inmate A had acted
    aggressively. The government noted that there had been a “heated discussion
    between Inmate A and Officer Childs,” and that Officer Childs had thought Inmate
    21
    A was engaging in a “deliberate attempt . . . to circumvent the search process.”
    The government then quoted the OIA Final Report‟s reproduction of Officer
    Childs‟s (discredited) account of the incident in which he stated that when he and
    his colleagues “attempted to search [Inmate A], [Inmate A] started kicking at the
    dog” and then stated that “Because [Inmate A‟s] actions interfered with the normal
    operations of the facility, I sprayed one burst of chemical agent . . . [and] then
    instructed [Inmate A] to seize [sic] his disruptive behavior.”
    The government not only credited a narrative of inmate aggression that the
    OIA had expressly discredited without disclosing that fact, thereby providing an
    incomplete recapitulation of the content of the OIA Final Report, it also cast doubt
    on the report even as to its purported focus—namely, whether Officer Childs had
    falsely indicated in reports that the inmate was unrestrained when Officer Childs
    sprayed him with a chemical agent. The government asserted that the text of
    Officer Childs‟s report was “ambiguous at best” and that “it is not apparent that
    [Officer Childs] lied in his report.” The government further stated that “[t]he
    conclusion that Officer Childs made a false or misleading statement is at odds with
    the body of the [Final OIA Report] and does not appear evident from the text of
    Officer Childs‟s [Incident Report].”
    22
    The government buttressed its intimations that the OIA investigation was
    unreliable when it argued its motion on the first day of trial.      Although the
    government acknowledged that it “expect[ed] [Officer Childs] to say that he [had
    been] demoted related to this incident,” it immediately undercut the force of this
    new disclosure by indicating that Officer Childs had had little opportunity to
    address or contest the report; indeed, the government asserted that Officer Childs
    “ha[d] never seen” the OIA Final Report, and thus he would not be able to speak to
    “the particulars.” Based on its description of the OIA Final Report as limited in
    scope and undependable in outcome, the government took the position that the
    April 2009 incident did not “bear[] directly upon” Officer Childs‟s veracity and
    thus was not the proper subject of cross-examination.
    The trial court relied on the government‟s representations regarding the OIA
    Final Report, and it denied repeated requests by the defense14 during the trial for
    disclosure of the actual report. Without the actual report, the defense had no
    ability to call the government‟s characterization of the report into question or to
    14
    Counsel for Mr. Woods played the lead role in advocating for disclosure
    of the OIA Final Report to the defendants.
    23
    persuade the court to order its disclosure.15 The court itself was in no position to
    assess the adequacy of the government‟s summary of the OIA investigation. The
    court had the government‟s five-page ex parte submission, but that incomplete
    document concluded with Officer Childs‟s (subsequently discredited) account of
    the incident with Inmate A; thus it said even less about Officer Childs‟s
    misconduct than the government‟s summary did.
    Mr. Morton and Mr. Vaughn did not receive a copy of the OIA Final Report
    until three months after trial, in February 2010, after they had already moved for a
    new trial on other grounds.16     In a “Supplemental Motion for a Judgment of
    15
    At the pretrial hearing, the trial court briefly considered ordering the
    government to disclose the report subject to a protective order, but it abandoned
    this option at the behest of the prosecution. The government asserted that, with
    respect to the other corrections officers named in the report, “there are employment
    issues,” and that it did not “believe that there is anything in the report that wasn‟t
    disclosed in the motion [to limit cross-examination of Officer Childs].”
    16
    Mr. Morton and Mr. Vaughn initially moved for a judgment of acquittal
    or in the alternative a new trial arguing, among other things, that their Sixth
    Amendment right to confrontation had been violated when they were denied a
    “meaningful” opportunity to cross-examine Officer Childs about the OIA Final
    Report. At a February 3, 2010 status hearing on that motion, the court ordered the
    government to disclose the full OIA Final Report pursuant to a protective order
    (the very procedure the government had successfully opposed during trial). The
    government subsequently disclosed the ten-page Final Report to the defense, but
    did not attach any of the appendices, apparently because the prosecutors did not
    have them; they had never asked DOC for a copy of the complete OIA Final
    Report with all of its attachments.
    24
    Acquittal and, in the Alternative, Defendant‟s Motion for a New Trial,” the defense
    argued that the government had violated its pretrial disclosure obligations under
    Brady. Sentencing was delayed and a series of hearings over a period of months
    followed.
    During this time, the government took no steps to inform the court that the
    five-page ex parte submission had been incomplete. The court was left to figure
    this out by itself, in the midst of a status hearing two months after the defense filed
    its Brady claim. When the court was shown the defense copy of the OIA Final
    Report, which included all ten pages, the court noted that the final pages looked
    unfamiliar. The government initially could not “represent what may . . . have
    happened.” It later informed the court that it had failed to provide the court with
    the full OIA Final Report “by inadvertence.” Even so, the government asserted
    that the “erroneously omitted portion” of the OIA Final Report changed nothing.
    Instead the government asserted that it had “fully disclosed and discussed” in its
    motion in limine “all of the information detailed in pages six through nine” of the
    report.
    Even after the court and the defense received complete copies of the OIA
    Final Report, the government stood by its characterization of the OIA investigation
    25
    as one solely concerned with Officer Childs‟s use of force and his alleged false
    reporting related to the use of force. It further denied that it was “aware” that
    Officer Childs had ever been formally disciplined in connection with this alleged
    misconduct. The government took the position that Officer Childs had “accepted a
    voluntary demotion” as an informal resolution to an inconclusive investigation
    regarding “allegations of false and/or misleading statements,” and that the only
    formal discipline Officer Childs had received in connection with the Inmate A
    incident was the Letter of Direction for improper use of force issued by Major
    Talley.17
    Almost a year after the defense filed its supplemental motion for a new trial
    raising a Brady claim, the government filed a document that could have clarified
    matters: the affidavit from OIA Investigator Collins.18 In this affidavit, OIA
    17
    When asked by the court at one post-trial hearing if this Letter of
    Direction “summarized aspects of the report,” the government answered, “that‟s
    correct,” even though the Letter of Direction was issued before the commencement
    of the OIA investigation and even though the OIA Final Report specifically
    determined that the Letter of Direction was inadequate because it failed to
    discipline Officer Childs for making a false report. See supra note 10.
    18
    By this time, the trial court had figured out that, based on the dates, Major
    Talley‟s Letter of Direction to Officer Childs could not summarize the OIA Final
    Report and directed the government to provide it with more information about
    what happened to Officer Childs after the completion of the OIA Final Report.
    Presumably, this is why the government filed OIA Investigator Collins‟s affidavit.
    26
    Investigator Collins explained that (1) Major Talley‟s Letter of Direction did not
    “supersede or impede” the OIA investigation; (2) He “officially completed” the
    OIA Final Report “[o]n June 27, 2009 . . . and forwarded it to Office of the
    Director for the DC Department of Corrections,” because the DOC OIA does not,
    “as a matter of routine or in this specific case. . . recommend disciplinary action”;
    (3) “Several months after the completion of [the OIA Final Report] [he] was
    verbally informed that Lieutenant Childs was demoted to the rank of Sergeant as a
    result of his actions on April 7, 2009”; and (4) “On September 15, 2009, [he]
    notified the U.S. Attorney‟s Office for the District of Columbia of the [OIA Final
    Report] concerning Lieutenant Childs and his subsequent demotion.”              OIA
    Investigator Collins also stated that he acquired (in January 2011) more details
    about Officer Childs‟s demotion. Specifically, he learned that Officer Childs had
    “received formal and written notification of his demotion on August 26, 2009 . . .
    from the Office of the Director of the Department of Corrections and [that this
    notification] was signed by Lieutenant Childs.” OIA Investigator Collins also
    learned from “a DC Department of Corrections, Human Resources Specialist” that
    Officer Childs had been “formally demoted . . . on September 13, 2009.” The
    government, however, filed this affidavit, without any accompanying explanation,
    after more than a year of post-trial litigation in this case, and it never
    27
    acknowledged that OIA Investigator Collins‟s sworn statements contradicted its
    earlier representations.
    When the parties returned to court a week after this filing, the court ruled on
    the defendants‟ supplemental motion for a new trial. The court determined that
    there had never been a “finding of untru[th] telling against Officer Childs.” The
    court further determined that the affidavit “essentially vindicates” that, “although
    the Internal Affairs Division did do an investigation of Officer Childs, no report
    was issued by that office and no action was taken by that office.” Accordingly, the
    trial court denied the motion from the bench “for the reasons stated in the
    government‟s opposition” to the defendants‟ motion.19
    19
    The trial court also referred to the unpublished memorandum opinion
    affirming co-defendant Bobby Johnson‟s conviction. See Johnson v. United States,
    No. 10-CF-205, Mem. Op. & J. (D.C. Mar. 9, 2011). The government has argued
    on appeal that that opinion is “instructive” if not dispositive of Mr. Morton and Mr.
    Vaughn‟s Brady claim. We disagree. Setting aside that the panel chose not to
    publish its disposition, the panel in that case considered a different issue (Mr.
    Johnson‟s assertion that his right to confront Officer Childs had been violated) on a
    very different record (the panel never had the benefit of the post-trial revelations
    that were made in this case).
    28
    B. Brady Analysis
    Our adversarial system is premised on the belief that “[s]ociety wins not
    only when the guilty are convicted but when criminal trials are fair.” 
    Brady, 373 U.S. at 87
    . Prosecutors have a critical role in ensuring the fairness of criminal
    trials. They are the representative of the sovereign, whose “interest . . . in a
    criminal prosecution is not that it shall win a case, but that justice shall be done.”
    Berger v. United States, 
    295 U.S. 78
    , 88 (1935); see also Miller v. United States,
    
    14 A.3d 1094
    , 1107 (D.C. 2011) (explaining that prosecutors must “seek justice
    before victory”). Prosecutors are thus obligated to play a dual role at trial; they
    must advocate for the government “with earnestness and vigor,” 
    Berger, 295 U.S. at 88
    , but they also have an obligation under Brady “to assist the defense in making
    its case.” United States v. Bagley, 
    473 U.S. 667
    , 675 n.6 (1985). In this “limited
    departure from a pure adversary model,” 
    id., prosecutors have
    a constitutionally
    imposed duty to disclose to the defense pretrial information that is “favorable to an
    accused . . . [and] material either to guilt or to punishment.” 
    Brady, 373 U.S. at 87
    .
    To determine on appeal whether the government, through its representatives
    in the trial court, has violated its obligations under Brady, we consider:         (1)
    whether the information in question is “favorable to the accused”; (2) whether this
    29
    information was possessed and suppressed by the government, “either willfully or
    inadvertently”; and (3) whether that information was material, i.e., whether there is
    “a reasonable probability that, had the evidence been disclosed, the result of the
    proceeding would have been different.”         
    Miller, 14 A.3d at 1109
    .       If the
    information was favorable, suppressed, and material, then reversal is required,
    “irrespective of the good faith or bad faith of the prosecution.” 
    Brady 373 U.S. at 87
    .
    Reviewing the trial court‟s legal conclusions de novo and its underlying
    findings of fact for clear error, 
    Miller, 14 A.3d at 1120
    , we consider each criterion
    for a Brady violation in turn.
    1. Favorable Information Subject to Disclosure
    At least in the abstract, it is easy to articulate what constitutes “favorable”
    information subject to disclosure under Brady. It is information “of a kind that
    would suggest to any prosecutor that the defense would want to know about it”
    because it helps the defense. See 
    Miller, 14 A.3d at 1110
    (quoting Leka v.
    Portuondo, 
    257 F.3d 89
    , 99 (2d Cir. 2001)). The defense perspective controls. See
    
    id. (“[T]he critical
    task of evaluating the usefulness and exculpatory value of the
    30
    information is a matter primarily for defense counsel, who has a different
    perspective and interest from that of the police or prosecutor.” (quoting Zanders v.
    United States, 
    999 A.2d 149
    , 164 (D.C. 2010))).
    Favorable information includes impeaching information.          See Giglio v.
    United States, 
    405 U.S. 150
    , 154-55 (1972). Indeed, although the Supreme Court
    held in 
    Bagley, 473 U.S. at 676
    , that the failure to disclose impeaching information
    is not “more egregious” than a failure to disclose affirmatively exculpatory
    information, both the Supreme Court and this court have repeatedly made clear that
    impeaching information does not have a lesser standing in the context of the
    government‟s Brady disclosure obligations. Rather, “[t]he jury‟s estimate of the
    truthfulness and reliability of a given witness may well be determinative of guilt or
    innocence.” 
    Bagley, 473 U.S. at 676
    (quoting Napue v. Illinois, 
    360 U.S. 264
    , 269
    (1959)); see also Bennett v. United States, 
    797 A.2d 1251
    , 1256 (D.C. 2002)
    (“Impeaching evidence is exculpatory.” (internal quotation marks omitted)).
    In this case, whether favorable information existed that was subject to
    disclosure under Brady turns on how one characterizes the OIA investigation and
    its outcome. When the trial court denied Mr. Morton‟s and Mr. Vaughn‟s motion
    for a new trial, it accepted the government‟s representations that (1) the OIA
    31
    investigation concerned Officer Childs‟s use of force and alleged false reporting
    related to his use of force, and (2) Officer Childs‟s demotion was something more
    in the nature of an administrative plea deal to resolve an inconclusive inquiry that
    ultimately was unrevealing regarding Officer Childs‟s credibility. As an appellate
    court, we ordinarily defer to the trial court‟s findings of fact, unless those findings
    are clearly erroneous. See 
    Miller, 14 A.3d at 1120
    . Here, record documents, the
    OIA Final Report and OIA Investigator Collins‟s affidavit, contradict the court‟s
    findings. We recognize that the trial court was constrained in its ability to assess
    these    documents   by    the   government‟s     late   production   and   continued
    misrepresentation or nondisclosure of the information in its possession. Unlike the
    trial court, however, we have had, from the outset of our review, the entire OIA
    Final Report with its appendices. With these advantages that the trial court did not
    share, we conclude that the trial court was misled and that its adoptive fact-finding
    was clearly wrong.
    Although the purpose of the OIA investigation as articulated in the OIA
    Final Report was “to identify the facts and circumstances regarding the use of [a
    chemical agent] by Lieutenant Angelo Childs” in April 2009, the report itself
    reveals that the investigation went beyond an inquiry into whether Officer Childs
    complied with use-of-force guidelines.         Ultimately, the OIA determined that
    32
    Officer Childs and his fellow DOC Officers had falsely accused Inmate A of
    assaultive behavior, and they had all filed false reports to this effect. The OIA also
    determined that Officer Childs falsely suggested that the inmate was unrestrained
    and Officer Childs sprayed him with a chemical agent to stop the (fabricated)
    assault. OIA Investigator Collins‟s affidavit completes the story. The inescapable
    inference is that the Office of the Director credited all the conclusions of the OIA
    Final Report and as a consequence meted out significant discipline by demoting
    Officer Childs from Lieutenant to Sergeant.20
    Once we clarify the actual subject and the apparent outcome of the OIA
    investigation, the determination that this information was favorable information
    subject to disclosure under Brady is not difficult. The OIA‟s determination of
    Officer Childs‟s false reporting was clearly impeaching, and was the sort of
    information in which any competent defense lawyer would have been intensely
    20
    The government has never denied that Officer Childs was demoted in
    connection with the Inmate A incident detailed in the OIA Final Report; it simply
    presented the contents of that report as something other than they are. One might
    try to argue that Officer Childs‟s demotion may have been related to only some but
    not all of the misconduct actually found by the OIA (e.g., the improper use of force
    but not the false reporting). But such an argument would be unpersuasive as
    Officer Childs had already been disciplined (via the Letter of Direction) for his
    improper use of force, and the submission of false reports—in particular reports
    falsely accusing an inmate of criminal conduct—are hardly insignificant.
    33
    interested. See Milke v. Ryan, 
    711 F.3d 998
    , 1007 (9th Cir. 2013) (“That [a law
    enforcement officer] was disciplined for lying on the job obviously bears on his
    credibility and qualifies as Giglio evidence.”).
    Of course the favorability of the OIA Final Report does not turn on its
    ultimate truth or the government‟s assessments thereof. The government could not
    withhold this information because it did not trust the conclusions of the OIA Final
    Report, or because it did believe its witness, Officer Childs, who professed
    innocence of false reporting21 and asserted ignorance of the reason for his
    discipline.22 As we said in Zanders and Miller, “[i]t is not for the prosecutor to
    decide not to disclose information that is on its face exculpatory based on an
    assessment of how that evidence might be explained away or discredited at trial, or
    ultimately rejected by the fact finder.” 
    Miller, 14 A.3d at 1110
    (quoting 
    Zanders, 999 A.2d at 164
    ); see also Smith v. Cain, 
    132 S. Ct. 627
    , 630 (2012) (holding that a
    21
    See infra pp. 46-47.
    22
    We note that the documentation of the notice of this action that Officer
    Childs should have received, see supra note 12, is not in the record. But the record
    does include OIA Investigator Collins‟s sworn statements giving the specific dates
    on which notice was issued and became effective and affirming his understanding
    that Officer Childs signed this notice, thus indicating that the requisite notice
    requirements were followed. We further note that in conformance with these
    regulations Officer Childs was given notice (which he signed) of the far less
    consequential (and subsequently deemed inadequate) Letter of Direction issued by
    Major Talley.
    34
    witness‟s inconsistent statements were subject to disclosure notwithstanding
    government‟s “argument . . . that the jury could have disbelieved [the] undisclosed
    statements”).
    2. The Government Suppressed Favorable Information in its
    Possession.
    When the government possesses favorable information subject to disclosure
    under Brady, it has an obligation to disclose this information to the defense in a
    timely and complete manner. In this case, there is nothing in the record to indicate
    that the government ever responded to the Brady request made by the defense
    months before trial23 or that it volunteered Brady information to the defense in the
    typical manner by sending the defense a disclosure letter. Ultimately, the defense
    did not obtain a copy of the OIA Final Report until three months after trial, albeit
    without the appended material, and it was not given OIA Investigator Collins‟s
    23
    Coincidentally, counsel for Mr. Morton made a Brady request for, inter
    alia, any “information which tends to show a government witness‟ bias or
    corruption . . . or which otherwise impeaches the witness‟ testimony” on April 10,
    2009, one day before the OIA investigation into Officer Childs‟s false reporting
    began. But whether or not defense counsel made a Brady request, the government
    had an independent obligation to disclose the favorable information in its
    possession. See United States v. Agurs, 
    427 U.S. 97
    , 107 (1976).
    35
    affidavit until over a year after trial, a week before the trial court ruled on its post-
    trial Brady claim.     Nevertheless, the government argues that it fulfilled its
    disclosure obligations when it filed, a week before trial, its motion in limine to
    preclude cross-examination of Officer Childs about the OIA Final Report and
    provided a “summary of the complete Final Report.” We cannot agree.
    To begin with, there was nothing about the motion in limine that put the
    defense on notice that the government was disclosing Brady information. The
    motion never cited Brady, much less indicated that the government was attempting
    “to assist the defense in making its case.” 
    Bagley, 473 U.S. at 675
    n.6. Instead,
    the object of the motion in limine was to preclude defense cross-examination of a
    government witness. This is not an elevation of form over substance. As we said
    in Miller, Brady does not authorize the government to engage in a game of hide-
    and-seek, or require the defense to “scavenge for hints of undisclosed Brady
    
    material.” 14 A.3d at 1113
    (quoting Banks v. Dretke, 
    540 U.S. 668
    , 695 (2004)).
    But that is precisely what the defense was forced to do in this case. Thus, at his
    first opportunity to address the court about the government‟s motion in limine,
    defense counsel told the court that he was “just basically hitting in the dark” and he
    was “not sure what the finding [of the DOC OIA] says”:
    36
    [I]f I hadn‟t read the motion closely, I wouldn‟t even have known
    [that the government might possess Brady information]. It wasn‟t as
    if [the prosecutors] called me and told me, I have a report you need to
    see. I just got this in the motion, and the motion, ironically, was to
    actually suppress or limit the use of this information while it‟s being
    given to me, even though it wasn‟t really being given to me; it was
    just being alluded to or stated, but it‟s—I don‟t have the actual report
    to this day.
    In any event, the government‟s disclosure was not timely, accurate, or
    complete. Accordingly, we conclude that the government suppressed favorable
    information in its possession.
    a. As a Brady Disclosure, the Motion in Limine Was Not
    Timely
    The government‟s obligation to make timely disclosures is grounded in the
    very reason Brady disclosures are required:         to provide protection against
    miscarriages of justice. 
    Miller, 14 A.3d at 1107
    . The goal of ensuring that our
    “adversary system of prosecution [does not] descend to a gladiatorial level
    unmitigated by any prosecutorial obligation for the sake of truth,” Kyles v. Whitley,
    
    514 U.S. 419
    , 439 (1995), is not achieved by last-minute information dumps.
    Rather, where disclosure of Brady is concerned, there is no time for strategic delay
    and “as soon as practicable” should be the approach. See 
    Miller, 14 A.3d at 1108
    (explaining that “a strategy of delay and conquer . . . is not acceptable” (internal
    37
    citation and quotation marks omitted)); see also 
    id. at 1111
    (rejecting the rationale
    that “better late than never” is good enough and endorsing the ABA standards
    requiring Brady disclosure “at the earliest feasible opportunity . . . as soon as
    practicable following the filing of charges” (internal quotation marks omitted)).
    Certainly, Brady disclosures are required “well before the scheduled trial date,”
    
    Zanders, 999 A.2d at 164
    ; Perez v. United States, 
    968 A.2d 39
    , 66 (D.C. 2009)
    (Brady requires “timely, pretrial disclosure”). Only in this way can we ensure
    “defense counsel [has] an opportunity to investigate the facts of the case and, with
    the help of the defendant, craft an appropriate defense.” 
    Perez, 968 A.2d at 66
    ; see
    also 
    Miller, 14 A.3d at 1111
    (“[A]s we have repeatedly recognized, exculpatory
    evidence must be disclosed in time for the defense to be able to use it effectively,
    not only in the presentation of its case, but also in its trial preparation.”); 
    Boyd, 908 A.2d at 57
    (“[T]imely disclosure . . . can never be overemphasized.”).
    By no means can the government‟s motion in limine constitute a timely
    pretrial disclosure of the information it possessed about Officer Childs‟s discipline
    as a result of the OIA investigation. The motion in limine provided no information
    on this subject although—according to the affidavit from OIA Investigator Collins
    that the government filed with the court—the “U.S. Attorney‟s Office” was
    informed of the OIA Final Report “concerning Lieutenant Childs and his
    38
    subsequent demotion” nearly two months before the government filed this motion.
    The government did not reveal that Officer Childs had been demoted until the first
    day of trial, when it briefly noted that Officer Childs was demoted “related to” the
    April 2009 incident that it had incompletely summarized in its motion in limine.
    The government did not provide any further details about when or how this
    discipline had been imposed until it filed OIA Investigator Collins‟s affidavit
    thirteen months after trial.
    But the government‟s disclosure obligations were triggered well before the
    DOC decided to demote Officer Childs. The government had an obligation to
    notify the defense that Officer Childs was under investigation by the DOC OIA.
    See United States v. Bowie, 
    198 F.3d 905
    , 908 (D.C. Cir. 1999) (determining that
    the prosecution had a duty to disclose the fact that one of its police officer
    witnesses had become “the subject of an investigation into the truthfulness of his
    testimony” in another case); see also Bullock v. United States, 
    709 A.2d 87
    , 92-93
    (D.C. 1998) (remanding to trial court to develop record on whether government
    should have disclosed that testifying law enforcement officer was under
    investigation).   As to the OIA investigation, which began in April 2009 and
    39
    concluded in June 2009, the government‟s motion in limine, filed a week before
    the November 2009 trial, was not an “as soon as practicable” Brady disclosure.24
    Accepting for the sake of argument the government‟s assertion that its
    motion in limine filed a week before trial was a Brady disclosure, the belatedness
    of this filing is not excused by the government‟s representation to the trial court
    that it did not learn of the DOC OIA investigation and its resulting report until
    “late summer.” Brady does not tolerate the “government[‟s] failure to turn over an
    easily turned rock.” United States v. Brooks, 
    966 F.2d 1500
    , 1503 (D.C. Cir.
    24
    That this information was impeaching does not diminish the
    government‟s obligation to learn of and disclose this information in a timely
    manner. No less than exculpatory information, the defense is entitled to make
    thoughtful, effective use of impeaching information in the preparation of its case.
    See 
    Miller, 14 A.3d at 1112
    (explaining that the opportunity for use of favorable
    information guaranteed by Brady is the “opportunity for a responsible lawyer to
    use the information with some degree of forethought” (quoting 
    Leka, 257 F.3d at 103
    )). The revelation that a witness may be untrustworthy or lying may open up
    new investigative avenues and require the contemplation of different strategies at
    trial. See, e.g., Sykes v. United States, 
    897 A.2d 769
    , 777-78 (D.C. 2006).
    Moreover, where, as here, the government disputes the meaning or value of the
    information it possesses, time must be afforded, well before trial, to litigate the
    government‟s disclosure obligations. As this case demonstrates, doing so on the
    eve of trial puts the defense at a strategic disadvantage and compromises the
    court‟s ability to thoughtfully assess the information at issue. See 
    Miller, 14 A.3d at 1111
    (discussing the difficulty of integrating Brady information on the eve of
    trial and noting that “[t]he defense may be unable to divert resources from other
    initiatives and obligations that are or may seem more pressing” (quoting 
    Leka, 257 F.3d at 101
    )).

    1992). “[T]he individual prosecutor has a duty to learn of any favorable evidence
    known to the others acting on the government‟s behalf in the case.” 
    Kyles, 514 U.S. at 437
    ; see also Robinson v. United States, 
    825 A.2d 318
    , 324 (D.C. 2003)
    (“[T]here is a duty to search branches of government „closely aligned with the
    prosecution.‟”). In this case, OIA Investigator Collins—the same investigator who
    investigated Officer Childs—was working closely with the U.S. Attorney‟s Office
    on the Spencer-White Case and had identified Officer Childs as central to the
    investigation of the Spencer-White attacks. For such an important witness so
    closely tied to the investigation, the government should have had the systems in
    place to ensure that it was alerted immediately about impeaching information. See
    
    Kyles, 514 U.S. at 419
    , 438 (observing that “the prosecutor has the means to
    discharge the government‟s Brady responsibility if he will,” and that “procedures
    and regulations can be established to carry [the prosecutor‟s] burden and to insure
    communication of all relevant information on each case to every lawyer who deals
    with it” (quoting 
    Giglio, 405 U.S. at 154
    )); see also 
    Brooks, 966 F.2d at 1502-03
    (observing that “the prosecutor‟s own interest in avoiding surprise at trial gives
    him a very considerable incentive to search accessible files for possibly
    exculpatory evidence, quite independent of Brady”).
    41
    In short, if it was a Brady disclosure at all, the government‟s motion in
    limine was not a timely one.
    b. As a Brady Disclosure, the Motion in Limine Was
    Neither Accurate Nor Complete
    In addition to its timing, we also consider the content of the motion in
    limine, in particular the “summary” of the OIA Final Report.           The defense
    attorneys were not satisfied with the government‟s summary; they pushed for
    disclosure of the “actual report.”    Even if it is theoretically possible for the
    government to fulfill its disclosure obligations under Brady by means of
    summaries of preexisting documents, such summaries must be “sufficiently
    specific and complete.” United States v. Rodriguez, 
    496 F.3d 221
    , 226 (2d Cir.
    2007).25 Again we consider the requisite level of detail from the perspective of the
    defense; where source documents exist, the government must “summarize[] . . .
    [them] with every detail that might have been relevant to defense counsel‟s
    25
    See also Matthews v. United States, 
    629 A.2d 1185
    , 1199-1200 (D.C.
    1993) (finding alleged Brady information was not “improperly withheld” where
    the prosecutor “explained to [the defendant] exactly what the [exculpatory]
    statement said”), abrogated on other grounds by Wilson-Bey v. United States, 
    903 A.2d 818
    (D.C. 2006) (en banc); Wiggins v. United States, 
    386 A.2d 1171
    , 1173
    (D.C. 1978) (holding that the government complied with Brady when it disclosed
    grand jury testimony in a “substantially verbatim” account).
    42
    preparation as counsel viewed the case.” 
    Wiggins, 386 A.2d at 1178
    (Ferren, J.,
    concurring). This may be challenging for the government, which presumably is
    not privy to defense counsel‟s thoughts and theories pretrial. Accordingly, the
    government withholds source documents at its peril.
    Here, the government‟s motion in limine did not come close to satisfying our
    standards for the content of Brady disclosures. What the government called a
    “summary of an incident on April 6, 2009, in which DOC Internal Affairs issued a
    Final Report” was not a true summary of the OIA Final Report at all, much less a
    summary of all the favorable information in the government‟s possession regarding
    Officer Childs.
    The OIA Final Report had exposed what the OIA determined was an untrue,
    self-serving story by Officer Childs and two colleagues of an assault by an inmate.
    The government‟s summary, however, indicated that Inmate A had acted
    aggressively. The summary quoted Officer Childs‟s explanation, reproduced in the
    OIA Final Report, that “[b]ecause [Inmate A‟s] actions interfered with the normal
    operations of the facility,” he used a chemical agent on Inmate A and instructed
    him “to seize [sic] his disruptive behavior”—without qualifying that OIA had
    discredited this account because “video footage of the incident [did] not support”
    43
    it. Thus, the government reproduced and represented as essentially undisputed
    substantial portions of the very Incident Report the OIA determined contained a
    false account of the incident.
    The government‟s motion in limine not only presented as true that which
    OIA had determined false, it used that false story as the backdrop for its account
    that the OIA investigation was simply an inquiry as to whether Officer Childs had
    used excessive force on a restrained Inmate A and whether Officer Childs had
    engaged in possibly sloppy report-writing to the extent he incorrectly
    “suggest[ed]” that Inmate A was unrestrained.26 The government disputed in its
    motion in limine that this suggestion was “evident” from Officer Childs‟s incident
    report, and it refused to “concede” that Officer Childs had “in fact” made false or
    misleading statements with respect to whether Inmate A was handcuffed, even
    though the OIA had determined that, as part of his fabricated story of inmate
    26
    The government‟s summary does not mention the other two corrections
    officers who the OIA determined also submitted similarly false accounts of an
    inmate assault. But its story that the OIA investigation was solely about Officer
    Childs‟s possible improper use of force and sloppy report-writing falls apart when
    the full scope of the DOC investigation into the actions of three officers to frame
    an inmate for assault is revealed.
    We further question the government‟s attempt to summarize the report
    without obtaining the 76 pages of appendices that accompanied the report, where
    these appendices further demonstrated that the scope of the OIA investigation was
    not as the government represented.
    44
    assault, Officer Childs had misleadingly indicated that Inmate A was unrestrained.
    The government‟s omission of the disciplinary consequences of the OIA Final
    Report bolstered the inaccurate account of the OIA investigation in the
    government‟s summary.
    c. As a Brady Disclosure, the Motion in Limine Was Not
    Usable
    The adequacy of a Brady disclosure ultimately turns on “the sufficiency,
    under the circumstances, of the defense‟s opportunity to use the evidence when
    disclosure is made.” 
    Miller, 14 A.3d at 1111
    (quoting 
    Leka, 257 F.3d at 100
    ).
    Beyond the timing and the content of the motion in limine, the trial record reflects
    that the government never afforded defense counsel a meaningful “opportunity to
    use” the favorable information in the government‟s possession. 
    Id. The defense
    was never able to impeach Officer Childs with the OIA investigation or its
    disciplinary consequences. Moreover, the government and Officer Childs made
    representations at trial that blocked the court from acting to ensure that any
    favorable information in the government‟s possession would come to light and the
    defense would be able to use it.
    45
    The government maintained throughout trial that the OIA investigation was
    limited to an inquiry into use of force and alleged false reporting related to the use
    of force, which had no bearing on Officer Childs‟s credibility as an after-the-fact
    identification witness in the Spencer-White trial. The defense, ill-informed by the
    government‟s summary, could not expose the government‟s representations about
    the OIA investigation and its outcome as inaccurate, and could not persuade the
    trial court that a probing cross-examination was warranted. Instead, as counsel put
    it, they were forced to “tak[e] the [government‟s] representations for what the
    report said or didn‟t say” and did not “really have any facts about what happened
    or what was . . . alleged to even ask [Officer Childs].”
    Nevertheless, when Officer Childs took the stand, defense counsel attempted
    on cross-examination to “probe” the basis for the OIA investigation.             The
    government objected, and, relying on the government‟s representations, the trial
    court limited the defense to two questions: (1) if it was true Officer Childs had
    “submitted a false report to the Department of Corrections while [he] [was]
    working at the D.C. Jail” and (2) if it was true he had been “disciplined by the
    Department of Corrections for filing a false report.” To both questions, Officer
    Childs responded, “no.” The defense had no means of challenging these responses,
    46
    much less any basis to ask the court for more leeway in impeaching Officer Childs
    with his prior false reporting.
    Although the defense had been unsuccessful in its questioning, the trial court
    nonetheless tried to fulfill its “obligation to assure” itself that no Brady information
    had been withheld from the defense and that the defense had had a meaningful
    opportunity to confront Officer Childs. See 
    Boyd, 908 A.2d at 59
    . These efforts
    were for naught.
    The trial court questioned Officer Childs about false reporting out of the
    presence of the jury. In response, Officer Childs represented that DOC OIA “felt
    that I missed the inmate while he was in handcuffs” and that he had explained to
    DOC OIA that “that was an error. I do a lot of cutting and pasting. But I said if
    you look at the rest of my report, that I stated the inmate was standing in front of
    the bubble with the handcuffs on. So, how can I say that I applied handcuffs,
    right?”   The court asked Officer Childs whether he had been disciplined in
    connection with the OIA investigation. Officer Childs represented that he had
    received “a voluntary demotion” but that he “didn‟t understand it to be the result[]
    of any disciplinary action” and that “no one [had] told [him] the reason for the
    demotion.” The government did not seek to qualify or correct anything Officer
    47
    Childs told the trial court, even though the government (1) had a complete copy of
    the OIA Final Report which documented the OIA‟s determinations both that
    Officer Childs had made a false report about whether Inmate A was unrestrained
    and this false report was part of a larger false narrative of an inmate assault, and (2)
    had been informed by OIA Investigator Collins that the DOC Office of the
    Director had demoted Officer Childs after receiving the OIA Final Report.27
    The trial court then called only the government to the bench to ask about the
    five-page ex parte submission. The court stated that it “just want[ed] to make sure
    . . . . I have the entire filing, because mine stops at page 5, and there was no . . .
    discipline or resolution mentioned in the document . . . that I have a copy of.” The
    government did not alert the trial court that the ex parte submission was
    incomplete; instead, one of the trial prosecutors told the court, “[y]eah, mine is five
    pages long,” incorrectly indicating that the court had the full OIA Final Report.
    The same prosecutor further informed the court, “there is no discipline listed in the
    27
    Consistent with the Supreme Court‟s decision in 
    Napue, 360 U.S. at 269
    ,
    we acknowledged in Longus v. United States, 
    52 A.3d 836
    , 844 (D.C. 2012), that it
    is “[a] bedrock principle of due process in a criminal trial . . . that the government
    may neither adduce or use false testimony nor allow testimony known to be false
    to stand uncorrected.” See also Thompson v. United States, 
    45 A.3d 688
    , 691 n.4
    (D.C. 2012) (acknowledging the duty to correct false testimony extends beyond
    perjury to testimony that is false because it is “mistaken”). Neither Mr. Morton
    nor Mr. Vaughn raised a Napue claim in this case, however.
    48
    report itself,” but the prosecutor did not explain that the OIA only conducts
    investigations and does not make disciplinary decisions; nor did the prosecutor
    inform the court that the decision to demote Officer Childs for making false reports
    had been made by the proper authority, the DOC Office of the Director.
    The trial court subsequently put its understanding of the OIA investigation
    on the record:
    [W]e have a little more clarity concerning this incident. For your
    purposes, the report that was submitted to me, which is what I was
    just confirming with the government, is not in the form of a
    disciplinary action, which is why I followed up with the questions I
    had of Officer Childs, because—and I confirmed with the government
    that they weren‟t aware of any, quote, disciplinary action the way we
    would—I had envisioned it could be; that is, there’d be an
    adjudication and then a finding of false report. I think it sounds like
    there was an administrative resolution between the officer and the
    Department of Corrections.
    The court explained that in allowing any questions about the investigation, it had
    been “operating under the assumption that . . . we were talking about some sort of
    disciplinary action where there was a finding” but “we‟re far afield from that.”
    The court then observed that there was no “factual basis that would support going
    further on this matter, in terms of questioning.” Concluding the discussion, the
    court reiterated that “based on what I heard” it would not permit “additional
    49
    questioning . . . on what I, at this point, assess . . . to be a collateral matter, which
    was an informal resolution . . . of a disciplinary matter, without a finding of . . . a
    nontruth-telling event.28 Again the government stood silent.
    Based on the foregoing, we cannot say that the government, through its
    motion in limine, disclosed to the defense the favorable information in its
    possession in such a way as to allow the defense to use this information effectively.
    The government not only failed to give the defense (or the court) accurate or
    complete information, it then stood by at trial and allowed the defense‟s ignorance
    and the court‟s erroneous understanding of the pertinent facts to persist. The
    upshot was that the trial court did not permit thorough impeachment of Officer
    Childs on the subject of the OIA investigation and its disciplinary consequences
    because it was convinced that, on these topics, there was nothing to impeach
    Officer Childs about. In short, the government‟s motion in limine to preclude
    impeachment of Officer Childs cannot be construed as a Brady disclosure because
    28
    The government asserts that because the trial court indicated that it would
    be open to further argument on the subject and the defense failed to raise the issue
    again, the defense “arguably waived any claim that they were entitled to confront
    Sergeant Childs at trial with a copy of the Final Report.” We see no waiver where
    the defense—because of the government‟s suppression of favorable information—
    had nothing else to offer and no other means to persuade the court that its
    assessment of the OIA investigation was mistaken.
    50
    it worked—the government‟s motion prevented an effective cross-examination of
    Officer Childs on the subject of his prior false reporting.
    *             *            *
    In the absence of a timely, accurate, complete, or usable disclosure, we
    conclude that the government did not disclose to the defense the favorable
    information in its possession in this case.
    3. The Favorable Information Suppressed by the Government
    Was Material
    We next consider whether the favorable information withheld by the
    government was “material.” See 
    Miller, 14 A.3d at 1115
    . To assess materiality,
    we consider whether there is “a reasonable probability that, had the evidence been
    disclosed to the defense, the result of the proceeding would have been different.”
    
    Id. (quoting Bagley,
    473 U.S. at 682). The reasonable probability standard does
    not require a showing that it is more likely than not the defendant would have been
    acquitted. 
    Kyles, 514 U.S. at 434
    . Rather, since Brady is a rule of fairness, the
    materiality threshold is met if, in the absence of proper disclosure, we question
    whether the defendant received a fair trial and our “confidence” in the outcome of
    51
    the trial is thereby “undermine[d].”29 Id; see also 
    Cain, 132 S. Ct. at 630
    (quoting
    
    Kyles, 514 U.S. at 434
    ); United States v. Cuffie, 
    80 F.3d 514
    , 517 (D.C. Cir. 1996)
    (explaining that the proper focus “is on the „potential impact that the undisclosed
    evidence might have had on the fairness of the proceedings‟ rather than on the
    overall strength of the government‟s case” (quoting United States v. Smith, 
    77 F.3d 511
    , 515 (D.C. Cir. 1996))).
    Our materiality analysis in this case must begin with an assessment of
    Officer Childs‟s role in the government‟s case. Officer Childs was a critical
    witness, as the government conceded in its brief to this court.            Indeed, the
    government signaled Officer Childs‟s importance by filing its motion in limine to
    preclude his cross-examination about the OIA Final Report.                At trial the
    government‟s need for his testimony became apparent: Officer Childs was only
    one of two government witnesses who inculpated Mr. Morton and Mr. Vaughn in
    29
    The materiality assessment this court conducts on appellate review is
    necessarily different from the materiality assessment the government can make
    pretrial when assessing its Brady obligations, and we reiterate that prior to trial, the
    government must disclose information that is “arguably” material. 
    Boyd, 908 A.2d at 61-62
    ; see also 
    Miller, 14 A.3d at 1109
    (acknowledging there may be “a duty of
    disclosure even when the items disclosed subsequently prove not to be material.”
    (citing 
    Boyd, 908 A.2d at 60
    )).
    52
    the assault on Sergeant White, and he was objectively the stronger witness.30
    Similarly, it cannot reasonably be disputed that Officer Childs‟s credibility was a
    central issue in the case. In closing, the government argued that its case turned on
    the jury‟s assessment of the credibility of its witnesses and of Officer Childs in
    particular. See Lewis v. United States, 
    408 A.2d 303
    , 308 (D.C. 1979) (noting that
    the “substantial possibility . . . that impeachment with prior convictions will affect
    the outcome, whether it goes to general credibility . . . or to a more specific target
    of reliability, such as bias” is “especially strong in the case of a key government
    witness” (citation omitted)).
    Next, we consider the nature of the withheld information: It was powerfully
    impeaching. It did not simply establish that Officer Childs had a track record for
    untruthfulness. It established that he was willing to make false reports implicating
    inmates in assaults on law enforcement agents—the precise context of this case.
    See 
    Milke, 711 F.3d at 1007
    (concluding that suppressed information about a
    30
    The government argues on appeal that its case was “strong even without”
    Officer Childs. We cannot agree that a case based solely on the identification
    testimony of Sergeant Harper would have been “strong.” We further note that the
    government‟s assertion that “the jury was able to evaluate whether the tapes
    depicted appellants,” is inconsistent with its position that it needed the lay opinion
    testimony of Officer Childs and Sergeant Harper to assist the jury in identifying the
    individuals in the recordings of the attacks. See infra part IV.A.
    53
    police officer‟s untruthfulness would have undermined his credibility and
    demonstrated that he “had no compunction about abusing his authority with a
    member of the public” who was similarly situated to the appellant).
    This leads us to the ultimate question: Does the suppression of this
    information undermine our confidence in the fairness of the trial? We conclude it
    does. Had the defense and the court known the full details of the OIA‟s actual
    findings and of the discipline meted out by DOC as a result—and had the
    government known the defense knew—we think it likely that this case would have
    played out very differently.
    Preliminarily, we question whether the government would have made the
    same representations and whether Officer Childs would have given the same
    testimony.    But, at the very least, defense counsel would have had a firm
    foundation to press for much more leeway in cross-examining Officer Childs on
    the subject of his prior false reporting and resulting discipline, instead of “hitting in
    the dark.” See 
    Cuffie, 80 F.3d at 517
    (explaining that undisclosed evidence of
    untruthfulness is material if it “could have substantially affected the efforts of
    defense counsel to impeach the witness, thereby calling into question the fairness
    of the ultimate verdict” (quoting 
    Smith, 77 F.3d at 515
    ). “[A]s a general rule, a
    54
    defendant is entitled to wide latitude in presenting evidence tending to impeach the
    credibility of a witness, especially where[, as here,] that evidence relates to a key
    government witness.” Dockery v. United States, 
    746 A.2d 303
    , 306 (D.C. 2000)
    (internal quotation marks omitted); Shorter v. United States, 
    792 A.2d 228
    , 233
    (D.C. 2001) (noting that trial courts may not curtail cross-examination so as to
    “keep[] from the jury relevant and important facts bearing on the trustworthiness of
    crucial testimony” (internal quotation mark omitted)). Here it appears that the trial
    court would have granted the defense such leeway; indeed, the court all but said
    that had Officer Childs been disciplined for making a false report, it would have
    allowed the defense to engage in a very different cross-examination of Officer
    Childs. This court can readily envision a series of permissible, pointed questions
    by defense counsel that would have seriously damaged Officer Childs‟s credibility
    in the eyes of the jury—whether he answered them truthfully or tried to avoid
    giving a truthful answer.31 See 
    Milke, 711 F.3d at 1009
    (explaining how police
    officer could have been confronted with prior instances of untruthfulness).
    31
    Even assuming Officer Childs would have given the same denials, his
    testimony that he had not been demoted as a result of false reporting would have
    provided the basis for request by the defense to demand that the government
    correct his false or mistaken testimony. See supra note 27.
    55
    The government asserts, however, that it “would not have influenced the
    verdict” if Officer Childs had either (1) admitted that he had been “demoted
    because he had deployed a chemical agent on an inmate” or (2) explained that he
    had not “purposefully file[d] a false report” indicating the inmate was unrestrained.
    We reject the factual foundation for the government‟s argument; as explained
    above, the OIA Final Report documents an investigation that was centrally
    concerned with a false report of an inmate assault by Officer Childs and two fellow
    corrections officers to justify an improper use of force, Officer Childs was demoted
    because of this investigation, and we infer that he was so disciplined as a sanction
    for all the conduct detailed in the OIA Report, including the determinations of false
    reporting.
    The government also argues that disclosure of the OIA Final Report would
    have had little effect on the outcome of the trial because the defense could neither
    have inquired into it on cross-examination in any further depth, nor could it have
    introduced the report itself as extrinsic evidence.
    In the first alternative, the government takes the position that the defense
    “could not have confronted Sergeant Childs with the report itself in order to
    impeach his credibility” because “appellants have not shown that Sergeant Childs‟s
    56
    statements were false.” Thus, the government argues the defense could not have
    laid the requisite foundation for cross-examination about a prior bad act. See
    Sherer v. United States, 
    470 A.2d 732
    , 738 (D.C. 1983) (explaining that “a witness
    may be cross-examined on a prior bad act that has not resulted in a criminal
    conviction only where: (1) the examiner has a factual predicate for such question,
    and (2) the bad act bears directly upon the veracity of the witness in respect to the
    issues involved [in] the trial” (internal quotation marks omitted) (quoting United
    States v. Akers, 
    374 A.2d 874
    , 878 (D.C. 1977))). Again, the government seeks to
    dispute the validity of the DOC‟s determination of false reporting.         But, the
    government‟s disbelief in the accuracy of the OIA‟s findings is irrelevant, both to
    an assessment of its obligation to disclose this information under Brady and to an
    assessment of the use the defense could have made of this information at trial. The
    point is that, unlike in Sherer, where the defense proffer that a government witness
    had previously lied “was conclusory and based almost entirely on inadmissible
    
    hearsay,” 470 A.2d at 739
    , here there was an official finding of false reporting by a
    government agency. This official determination provided the defense with an
    ample “factual predicate” for questioning Officer Childs about false reporting.32
    32
    This factual predicate was not undermined by the absence of any record
    of Officer Childs‟s false reporting and demotion in his personnel file, which the
    trial court apparently reviewed but is not in the record on appeal. It was never
    established that Officer Childs‟s personnel file was complete and in fact the
    (continued…)
    57
    See 
    id. at 738;
    see also Wagner v. Georgetown Univ. Med. Ctr., 
    768 A.2d 546
    , 563
    (D.C. 2001) (finding that a professional association‟s findings recommending
    censure constituted a “more than sufficient factual predicate for the proposed cross
    examination” of a physician witness).
    In the second alternative, the government argues that the defense would not
    have been able to present extrinsic evidence of the OIA Final Report because it
    concerned a collateral issue. See Rowland v. United States, 
    840 A.2d 664
    , 680
    (D.C. 2004). Thus, the government argues that even if the defense had had the full
    report and information about the subsequent demotion, it would have been stuck
    with the testimony Officer Childs gave at trial, namely, his denials that he had filed
    a false report and that he had been demoted for filing a false report. Whether the
    defense could have introduced the actual OIA Final Report into evidence is an
    (…continued)
    personnel regulations allow for removal of documentation of discipline from an
    employee‟s file under certain circumstances. See 6-B DCMR § 1601.7 (2008).
    More fundamentally, there was never any question that Officer Childs was
    demoted in connection with the Inmate A incident. He admitted that he was. And
    even though he stated that he “didn‟t want to” take what he represented was a
    “voluntary demotion,” there is no indication in the record that he ever sought to
    administratively challenge this discipline or the underlying determination of
    misconduct on which it was based.
    58
    interesting but ultimately academic issue.33 Effectively, the government argues
    that Brady disclosure or no, nothing would have changed in how this case played
    out at trial. As explained above, we think that argument blinks reality. See 
    Milke, 711 F.3d at 1009
    (explaining how prior judicial determinations of police officer‟s
    untruthfulness “would have been a game-changer” on cross-examination even
    without proof of extrinsic evidence).
    33
    Extrinsic evidence is admissible to substantiate a claim of witness bias
    because bias is never a collateral issue. Martinez v. United States, 
    982 A.2d 789
    ,
    795 (D.C. 2009). Here we agree with the government that the defense could not
    have introduced the OIA Final Report to pursue a line of bias cross-examination on
    a theory that Officer Childs was testifying for the government to curry favor in his
    own misconduct proceedings. Because Officer Childs identified Mr. Morton and
    Mr. Vaughn before his false reporting incident took place and because he was
    demoted before he testified at their trial, the timing does not suggest an attempt to
    curry favor with the government while under investigation. Cf. 
    id. at 795
    (holding
    that officer‟s status as subject of an ongoing MPD investigation was admissible as
    evidence of bias). But proffering a “well-reasoned suspicion” that a witness has a
    motive to curry favor with the government is only one means of establishing the
    requisite “proper foundation” to pursue a bias line of cross-examination. See
    Howard v. United States, 
    978 A.2d 1202
    , 1207 (D.C. 2009). “Bias may be induced
    by a witness‟[s] like, dislike, or fear of a party, or by the witness‟[s] self-interest.”
    Dawkins v. United States, 
    41 A.3d 1265
    , 1271 (D.C. 2012). And this court has
    recognized that corruption bias, i.e., a willingness to give false testimony, is its
    own separately cognizable form of bias. See 
    Longus, 52 A.3d at 851-53
    ; In re
    C.B.N., 
    499 A.2d 1215
    , 1219-20 (D.C. 1985). Although the government argues
    that the defense should be limited in its materiality argument to the theory of bias it
    advanced at trial, we are not inclined to find waiver in light of the fact that the
    defense did not have the full report at trial. Our inquiry is not about what the
    defense did without the Brady material, but about what the defense would have
    done had it had the Brady material.
    59
    Based on the record before us, whether the government had an obligation to
    accurately and completely disclose the contents of the OIA Final Report and the
    DOC‟s consequent decision to demote Officer Childs should not have been a hard
    call for the government.34 And had the defense been able to impeach Officer
    Childs with the DOC‟s determination of his prior false reporting and consequent
    demotion, there is at least a reasonable probability that the jury would have
    weighed Officer Childs‟s testimony and the government‟s case differently. This
    concludes our materiality analysis for Mr. Morton. But for Mr. Vaughn, there is a
    coda. The suppressed impeachment evidence for Officer Childs was material only
    to the extent that Mr. Vaughn contested Officer Childs‟s identification. But Mr.
    Vaughn submitted a post-trial affidavit in which he admitted that he was the inmate
    Officer Childs had identified him to be and argued only that his actions had been
    34
    Indeed, we are left with many questions about the government‟s behavior
    in this case, including: (1) How could the government have so misconstrued the
    findings of the OIA investigation as memorialized in the full OIA Final Report as
    ultimately unrevealing regarding Officer Childs credibility? (2) How could the
    government have failed to realize at trial that it had not given the court the full OIA
    Final report, particularly when the trial court specifically asked if the five-page
    copy it had in hand was the complete report? (3) How could the government have
    made the representations it did about the consequences of the Inmate A incident or
    have allowed Officer Childs to testify without qualification about his lack of notice
    or understanding of those consequences, in light of the information contained in
    OIA Investigator Collins‟s sworn affidavit?
    But these questions ultimately go to whether the government acted in bad
    faith, which, as we noted at the outset, is irrelevant to the issue raised before this
    court: whether the government violated its constitutionally imposed disclosure
    obligations. See 
    Brady, 373 U.S. at 87
    ; 
    Miller, 14 A.3d at 1107
    .
    60
    misinterpreted—that he had not pushed Sergeant White; he had been trying to help
    him.   This admission negates our materiality determination.      In light of Mr.
    Vaughn‟s affidavit, which the government would be free to use as a party
    admission, we see little chance of a different result were Mr. Vaughn to be given a
    new trial. Thus, the government‟s Brady violation is reversible only with respect
    to Mr. Morton.
    C. Remand
    By now government prosecutors should know: “Betray Brady, give short
    shrift to Giglio, and you will lose your ill-gotten conviction.” United States v.
    Olsen, 
    737 F.3d 625
    , 633 (9th Cir. 2013) (Kozinski, C.J., dissenting from denial of
    petition for rehearing en banc). So it is for the government with respect to Mr.
    Morton‟s conviction; we reverse and remand his case for a new trial.
    Well before any such trial takes place,35 the court must confirm that the
    government has in fact provided to the defense all the favorable information in its
    35
    Some courts have held that where the government engages in deliberate
    Brady misconduct, a new trial should not be held. See Virgin Islands v. Fahie, 
    419 F.3d 249
    , 254-55 (3d Cir. 2005) (recognizing that “dismissal for a Brady violation
    may be appropriate in cases of deliberate misconduct”); United States v. Kojayan,
    (continued…)
    61
    possession. As far as we can tell, the government has never represented in this
    case that it has fulfilled its constitutional duty to learn of and disclose to the
    defense all the Brady information in its actual or constructive possession. See
    
    Kyles, 514 U.S. at 437
    . The government should be directed to make such a
    representation, in writing, filed with the trial court. See, e.g., 
    Milke, 711 F.3d at 1019
    (requiring, on remand, the state to make complete Brady disclosures
    regarding the subject police officer and to “provide a statement under oath from a
    relevant police official certifying that all of the records have been disclosed and
    none has been omitted, lost or destroyed”); United States v. Naegele, 
    468 F. Supp. 2d
    150, 155 (D.D.C. 2007) (directing government to “conduct all necessary
    searches and produce to the defendant any and all materials that are responsive” to
    prior Brady requests and “certify to the [c]ourt in writing that it has done so”). It
    also goes without saying that if any other instances of nondisclosure come to light,
    further “remedial sanctions” beyond a retrial may be needed. See Odom v. United
    States, 
    930 A.2d 157
    , 158-59 (D.C. 2007) (recognizing a trial court‟s broad
    (…continued)
    
    8 F.3d 1315
    , 1325 (9th Cir. 1993) (remanding to the trial court to consider whether
    to allow a new trial after a Brady violation); see also Sanders v. United States, 
    550 A.2d 343
    , 344-46 (D.C. 1988) (recognizing the trial court‟s “supervisory power to
    dismiss the indictment as a sanction for government misconduct”). We neither
    endorse nor foreclose such an argument by the defense on remand.
    62
    authority to fashion “appropriate remedial sanctions” so long as they are just under
    the circumstances).
    III.   Jury Instruction Error
    Although Mr. Vaughn obtains no relief on his Brady claim, we conclude that
    his conviction for aggravated assault must be reversed on other grounds. Mr.
    Vaughn argues that the trial court erred in instructing the jury as to the elements of
    this offense on a theory of aider and abettor liability. Because counsel did not
    object, this claim is subject to plain error review. See 
    Perez, 968 A.2d at 92
    . The
    government has conceded that the court‟s aiding and abetting instruction was
    plainly incorrect, satisfying the first two criteria for reversal. See Perry v. United
    States, 
    36 A.3d 799
    , 818 (D.C. 2011) (citing United States v. Olano, 
    507 U.S. 725
    ,
    732-36 (1993)). But the government argues that Mr. Vaughn cannot show the third
    criterion for plain error review, namely that this error “affect[ed] substantial
    rights.” 
    Id. We disagree,
    and because we also conclude that this error “seriously
    affect[ed] the fairness, integrity or public reputation of judicial proceedings,” 
    id., the fourth
    criterion for plain error review, we exercise our discretion to reverse.
    63
    Mr. Vaughn was charged with both aggravated assault and felony assault.
    As the more serious offense, the D.C. Code appropriately sets a high bar for
    aggravated assault. Whereas felony assault requires proof of “significant bodily
    injury”36 that a defendant caused “intentionally, knowingly, or recklessly,” D.C.
    Code § 22-404 (a)(2), aggravated assault requires proof of “serious bodily injury”37
    that a defendant either “knowingly or purposely cause[d]” or that resulted from
    conduct in which the defendant “[u]nder circumstances manifesting extreme
    indifference to human life . . . intentionally or knowingly engage[d] . . . [and]
    which create[d] a grave risk of serious bodily injury.” D.C. Code § 22-404.01; see
    also 
    Perry, 36 A.3d at 817
    .
    The problem in this case arose after the court correctly instructed the jury on
    the elements of principal liability for aggravated assault and felony assault. The
    trial court then explained that the jury could also convict if it determined a
    36
    “Significant bodily injury” is defined as “an injury that requires
    hospitalization or immediate medical attention.” D.C. Code § 22-404 (a)(2) (2012
    Repl.).
    37
    This court has defined “serious bodily injury” as an injury that causes “a
    substantial risk of death, unconsciousness, extreme physical pain, protracted and
    obvious disfigurement, or protracted loss of impairment of the function of a bodily
    member, organ, or mental faculty.” 
    Perry, 36 A.3d at 815
    n.29.
    64
    defendant had aided and abetted the principal offender. Whether the jury considers
    a defendant‟s criminal liability as a principal or as an aider or abettor, the requisite
    mens rea for the charged assault is the same. 
    Perry, 36 A.3d at 814-18
    ; see also
    
    Wilson-Bey, 903 A.2d at 837-38
    (holding that to be guilty as an aider or abettor, an
    accomplice must have the same mental state required for conviction as a principal).
    Although the court correctly charged the jury that it had to find the same mens rea
    to convict a defendant as a principal or an aider and abettor, it then gave an
    instruction for aider and abettor liability that inappropriately combined the
    standards for aggravated assault and felony assault. In effect, the court informed
    the jury that it could convict a defendant as an aider and abettor of an aggravated
    assault if it found that the defendant had the lesser mens rea for felony assault.38
    Under D.C. Code § 22-404.01 and Perry, this was error and plainly so.
    38
    In its discussion of aiding and abetting, the court instructed the
    jury:
    With respect to the charge of aggravated assault or
    assault with a significant injury, regardless of whether a
    Defendant is an aider and abettor or a principal offender,
    the Government must prove beyond a reasonable doubt
    that the Defendant personally acted with:
    (A) inten[t] to cause significant bodily injury to the
    complainant; or (B) [knowledge] that significant bodily
    injury to the complainant would result from his conduct;
    or (C) [awareness] of and disregard[] [for] the risk of
    significant bodily injury that his conduct created.
    65
    To demonstrate that this plain error warrants reversal, Mr. Vaughn must
    show prejudice, i.e., a “„reasonable probability‟ of a different outcome if the jury
    had been properly instructed.” 
    Perry, 36 A.3d at 818
    . This standard for assessing
    prejudice requires us to “make sense of the jury‟s verdict in light of the evidence
    presented and the instructions given to the jury.” 
    Id. at 821.
    The first step of the inquiry is whether we can discern with any assurance
    that Mr. Vaughn was convicted of aggravated assault on a theory of principal
    liability—on which the jury had earlier been correctly instructed—or whether there
    is a reasonable probability that Mr. Vaughn was convicted on a theory of aiding
    and abetting liability—on which the jury never received a correct instruction. On
    the record before the court it is clear that the jury could not have convicted Mr.
    Vaughn of aggravated assault as a principal. No evidence was introduced at trial
    that he caused Sergeant White to suffer the serious bodily injury alleged, i.e., his
    subsequent unconsciousness and head injuries, either by personally inflicting these
    injuries or creating the grave risk that these particular injuries would occur.39 The
    39
    We question whether the government presented evidence that Sergeant
    White suffered serious bodily injury at all. The government presented evidence
    that Sergeant White briefly lost consciousness following the attack, that the head
    injuries he incurred did not cause substantial pain, and that, although he sought
    medical care, he fully recovered from these injuries without medical intervention.
    (continued…)
    66
    government‟s theory at trial was that Mr. Vaughn was the inmate in white, whose
    only contact with Sergeant White was to give him “one good shove.” This push
    knocked Sergeant White against a table. But the recorded footage shows that
    Sergeant White immediately arose from the table and walked away; 40 meanwhile
    the inmate in white retreated and did not engage in any further aggressive action.
    The government acknowledged in closing that Mr. Vaughn was not present for the
    subsequent attack on Sergeant White; the government highlighted for the jury that
    Mr. Vaughn was not on the scene because “he [ran] back upstairs” and did not
    “stand there to help.” The complete lack of evidence that Mr. Vaughn principally
    (…continued)
    This appears to fall well below the “high threshold of injury,” Jenkins v. United
    States, 
    877 A.2d 1062
    , 1069 (D.C. 2005), we have set to prove aggravated assault.
    See, e.g., Jackson v. United States, 
    940 A.2d 981
    , 983-84 (D.C. 2008) (declining to
    find serious bodily injury where victim was forcibly raped and beaten in the head
    with a hammer); Bolanos v. United States, 
    938 A.2d 672
    , 679 (D.C. 2007)
    (declining to find serious bodily injury where victim was stabbed in arm and
    stomach and required surgery to repair perforation to his intestine); see also
    Swinton v. United States, 
    902 A.2d 772
    , 775 (D.C. 2006) (explaining that in cases
    finding serious bodily injury, the injuries were “usually . . . life-threatening or
    disabling. The victims typically required urgent and continuing medical treatment
    (and, often, surgery), carried visible and long-lasting (if not permanent) scars, and
    suffered other consequential damage, such as significant impairment of their
    faculties. In short, these cases have been horrific.”). But Mr. Vaughn has not
    argued that the nature of Sergeant White‟s injuries preclude his conviction for
    aggravated assault and we need not reach this issue in light of our disposition
    above.
    40
    The recorded footage does not show, and the government presented no
    other evidence regarding, the point in time when Sergeant White was brought to
    the floor.
    67
    caused serious bodily injury makes it clear that there is at least a reasonable
    probability that the jury relied on a theory of aiding and abetting to convict Mr.
    Vaughn of aggravated assault. See 
    Perry, 36 A.3d at 821
    .
    Focusing on aiding and abetting liability, we next consider whether it was
    reasonably probable that the jury‟s determination of guilt turned on the mistakenly
    minimized intent element in the aiding and abetting instruction. See 
    id. We think
    it was. To discern Mr. Vaughn‟s mental state, the jury could only look to and draw
    inferences from his conduct. From Mr. Vaughn‟s “one good shove” that caused
    Sergeant White to briefly lose his balance, it seems highly unlikely the jury would
    infer that Mr. Vaughn “himself intended to cause serious bodily injury.” 
    Perry, 36 A.3d at 817
    . Thereafter, Mr. Vaughn did not seek to press his advantage and strike
    Sergeant White again. Instead, by immediately retreating, he allowed Sergeant
    White to recover and move away.        Similarly, from Mr. Vaughn‟s “one good
    shove,” it seems unlikely the jury would infer that Mr. Vaughn acted intentionally
    to “create[] a grave risk of serious bodily injury.” 
    Id. at 817
    (internal quotation
    marks omitted). At the time of Mr. Vaughn‟s single push, no inmate had acted
    aggressively toward Sergeant White; nor is there any evidence in the record as to
    when the subsequent attack began. And, although one might argue that, at the time
    of his push, the ensuing escalation of events was reasonably foreseeable to Mr.
    68
    Vaughn, diminishing the requisite aider and abettor mens rea for aggravated
    assault to reasonable foreseeability is precisely what this court held in Perry was
    disallowed under Wilson-Bey. 
    Perry, 36 A.3d at 817
    -18 (rejecting under Wilson-
    Bey a jury instruction that would allow appellants to be “liable for aggravated
    assault for negligently having begun a[n] . . . assault if it was „natural and
    probable‟ that the melée would escalate to severe kicking by someone else, even if
    appellants did not themselves have the intent to cause serious bodily injury or
    „manifest extreme indifference to human life‟”). Thus, we find that there is at least
    a “reasonable probability” that Mr. Vaughn would not have been convicted of
    aggravated assault absent the error in the aiding and abetting jury instruction.
    Lastly, we conclude that the fourth element of plain error review is
    satisfied.41 Mr. Vaughn was “wrongly convicted of aggravated assault on an
    aiding and abetting theory of liability, without a jury determination that [he] had
    the mens rea required for conviction of that offense,” and such “[a] wrongful
    41
    The government asserts that “appellant is not entitled to reversal because
    he cannot satisfy the third and fourth plain-error requirements,” but save one
    citation, its brief contains no further reference to the fourth prong of plain error
    review.
    69
    conviction necessarily affects the integrity of this proceeding and impugns the
    public reputation of judicial proceedings in general.” 
    Perry, 36 A.3d at 822
    .
    Because Mr. Vaughn has satisfied all the elements of plain error review, we
    exercise our discretion to reverse his conviction for aggravated assault.
    IV.   Other Issues
    A. Admission of Identification Testimony
    Mr. Morton and Mr. Vaughn also argue that the court should not have
    permitted Sergeant Harper and Officer Childs to testify as identifying witnesses
    because their testimony did not satisfy the standards outlined in Sanders v. United
    States, 
    809 A.2d 584
    , 596 (D.C. 2002). Discerning no abuse of discretion, 
    id. at 590,
    we affirm the trial court‟s Sanders ruling.42
    42
    The government argues that appellants have waived their argument on
    this issue by failing to raise it before the trial court and asserts that this issue must
    be reviewed for plain error review if it is considered at all. We see no reason to
    delve into a preservation analysis in light of our determination that the trial court
    did not abuse its discretion.
    70
    In Sanders, this court held that “lay witness opinion testimony regarding the
    identity of a person in a surveillance photograph or a surveillance videotape is
    admissible into evidence, provided that such testimony is: (a) rationally based on
    the perception of a witness who is familiar with the defendant‟s appearance and
    has had substantial contact with the defendant; and (b) helpful to the factfinder in
    the determination of a fact in 
    issue.”43 809 A.2d at 596
    . Both Mr. Morton and Mr.
    Vaughn contend that the trial court erred when it allowed Officer Childs and
    Officer Harper to provide identification testimony where the evidence did not
    establish sufficient familiarity and substantial contact with Mr. Morton or Mr.
    Vaughn.44
    43
    The evidentiary rule in Sanders is derived from Rule 701 of the Federal
    Rules of Evidence, which this court has adopted in substance. See King v. United
    States, 
    74 A.3d 678
    , 681 n.13 (D.C. 2013).
    44
    Both Mr. Morton and Mr. Vaughn fault the trial court for not making
    specific findings on the Sanders issue, but trial counsel never requested such
    findings. See Tyson v. United States, 
    30 A.3d 804
    , 806 (D.C. 2011) (“[W]hen a
    request for special findings is not timely made, the right to such findings is
    generally regarded as having been waived.”). Indeed, as noted above, there is
    some question whether this issue was waived or properly preserved. See supra
    note 42.
    71
    We consider it a close call whether, under Sanders, Officer Childs and
    Officer Harper had sufficient contact with and knowledge of the defendants.
    Certainly, this case does not involve the familial or close personal relationships
    seen in Sanders or other cases in which identification testimony has been admitted
    in federal courts under Rule 701.45 But the government did present evidence that
    the officers, over a period of months, had daily interaction with Mr. Morton and
    Mr. Vaughn throughout the routine functions of their jobs—interaction which gave
    rise to familiarity and particular knowledge of their physical features.         We
    conclude it was therefore within the discretion of the trial court to find that there
    was an adequate foundation for the proffered identification testimony. Both Mr.
    Morton and Mr. Vaughn point to weaknesses in the officers‟ trial testimony, but
    such weaknesses are classic fodder for cross-examination; they do not bear on the
    court‟s initial Sanders ruling.46
    45
    See 
    Sanders, 809 A.2d at 593
    n.10 (allowing identifying testimony from
    defendant‟s neighbor of twenty-five years, former boss, and ex-girlfriend, among
    others); see also, e.g., United States v. Jackman, 
    48 F.3d 1
    , 2 (1st Cir. 1995)
    (allowing identifying testimony from defendant‟s ex-wife and two personal
    acquaintances); United States v. Stormer, 
    938 F.2d 759
    , 762 (7th Cir. 1991)
    (allowing identifying testimony where witnesses were acquainted with defendants
    for several years); United States v. Borrelli, 
    621 F.2d 1092
    , 1095 (10th Cir. 1980)
    (allowing identifying testimony from defendant‟s stepfather).
    46
    Mr. Morton also argues that Sergeant Harper and Officer Childs should
    not have been permitted to testify because the government failed to establish that
    their testimony would be helpful. But this argument is largely a repeat of his
    (continued…)
    72
    B. Ineffective Assistance of Counsel
    Mr. Vaughn also argues that the representation he received at trial was
    constitutionally ineffective. To establish ineffective assistance of counsel, the
    defendant must show that counsel‟s performance was deficient and that this
    deficient performance prejudiced the defendant. Blakeney v. United States, 
    77 A.3d 328
    , 340 (D.C. 2013) (citing Strickland v. Washington, 
    466 U.S. 668
    , 686-87
    (1984)).    In reviewing the trial court‟s determination that counsel was not
    ineffective, we accept the trial court‟s factual findings unless they are without
    evidentiary support in the record, but review the legal conclusions regarding the
    constitutional significance of those findings de novo. 
    Id. at 341.
    We affirm the
    trial court‟s finding that Mr. Vaughn failed to establish deficient performance on
    the part of his trial counsel.
    (…continued)
    challenge to the quality and quantity of the officers‟ “personal and direct contacts”
    with Mr. Morton. To the extent he focuses on other factors, he identifies one in
    particular, “the quality of the video or photo,” that defeats his argument. Indeed,
    elsewhere in his brief, Mr. Morton acknowledges the recorded footage used by the
    government in this case was “dark, pix[e]lated, „jerky,‟ and „blurry.‟” In Sanders,
    we stated that testimony may be helpful if the image of the defendant in the
    videotape or photograph is “obscured.” 
    Sanders, 809 A.2d at 596
    .
    73
    In order to show deficient performance, the defendant must “show[] that
    counsel made errors so serious that counsel was not functioning as the „counsel‟
    guaranteed the defendant by the Sixth Amendment.” 
    Strickland, 466 U.S. at 687
    .
    Mr. Vaughn first claims that his trial counsel‟s representation was deficient
    because counsel failed to investigate and prepare witnesses who could have
    testified at trial. But the trial court found, consistent with trial counsel‟s testimony
    in the post-trial proceeding, that counsel interviewed the witnesses that Mr.
    Vaughn provided, and ultimately determined that their testimony would not be
    helpful where it contradicted the evidence depicted in the videos. The ultimate
    decision not to call these witnesses “is a judgment left almost exclusively to
    counsel,” and we see nothing on this record to call that judgment into question.
    Oliver v. United States, 
    832 A.2d 153
    , 158 (D.C. 2003) (internal quotation marks
    omitted).
    Mr. Vaughn also claims that he would have exercised his right to testify but
    for counsel‟s failure to prepare him to do so. The trial court, however, credited
    counsel‟s testimony in post-trial proceedings that he had met with Mr. Vaughn
    several times prior to trial and asked a co-defendant‟s counsel to conduct a mock
    74
    cross-examination of Mr. Vaughn. This, too, is well within the range of reasonable
    attorney performance.
    Finally, Mr. Vaughn argues that counsel presented defense theories that
    were inconsistent. Counsel argued that the person seen in the recorded footage
    wearing white was not Mr. Vaughn, but in any event, if the jury thought that
    person was Mr. Vaughn, the alleged push was insufficient to satisfy the element of
    serious bodily injury required for aggravated assault. Even if this argument in the
    alternative constituted a contradiction, a basic principle of criminal law is that a
    defendant may present inconsistent and contradictory defenses. See, e.g., McClam
    v. United States, 
    775 A.2d 1100
    , 1104 (D.C. 2001).
    For these reasons, we affirm the trial court‟s denial of Mr. Vaughn‟s
    ineffective assistance of counsel claim.
    75
    C. Sufficiency of the Evidence
    Both Mr. Morton and Mr. Vaughn raise challenges to the sufficiency of the
    government‟s evidence. Mr. Morton effectively reargues his Sanders challenge in
    his attack on the sufficiency of the evidence when he argues that he could not have
    been convicted “without the non-eyewitness testimony” of the corrections officers
    who viewed the videotape, and that even with this testimony “the jury must have
    been left to speculate about whether, in fact, the video identifications had any
    basis.” We have affirmed the trial court‟s Sanders ruling, but even if we had not,
    we consider even wrongfully admitted evidence in assessing sufficiency, Mitchell
    v. United States, 
    985 A.2d 1125
    , 1134-35 (D.C. 2009). Viewing the totality of the
    evidence presented in the light most favorable to the government, see 
    id. at 1133,
    we reject Mr. Morton‟s sufficiency challenge to his convictions for aggravated
    assault and assault on a law enforcement officer.
    For his part, Mr. Vaughn attacks the sufficiency of the government‟s
    evidence against him on the ground that the jury was “misled” by the poor quality
    of the video footage of his contact with Sergeant White and failed to discern that
    his “true act” was not to attack Sergeant White, as the government argued, but
    76
    rather to come to his aid and defend him against attack by others. Again, we view
    the evidence in the light most favorable to the government. The jury could have
    viewed the video and concluded that it showed Mr. Vaughn engaging in an
    altercation with Sergeant White and taking an action that it could reasonably have
    interpreted as a push.
    V.    Conclusion
    For the reasons set forth above we affirm Mr. Vaughn‟s conviction for
    assault on a law enforcement officer; we reverse his conviction for aggravated
    assault; we reverse Mr. Morton‟s convictions for assault on a law enforcement
    officer and aggravated assault; and we remand for further proceedings consistent
    with this opinion.
    So ordered.
