180 A.3d 45
D.C.2018Background
- In May 2014 police chased Shawn Smith; Officer Williams recovered a handgun from a yard and Smith was later arrested; Williams photographed the gun on his cell phone and put it into evidence; no fingerprints/DNA linked Smith to the gun.
- Mid-trial, after opening statements, the government disclosed a preliminary IAD report that Officer Williams was under investigation for an alleged excessive-force incident (the "Barkley" incident) occurring months after the Smith incident; that report included inconsistent witness statements and referenced Barkley’s cell-phone video.
- Defense sought to use the IAD materials to pursue cross-examination aimed at corruption bias (that Williams would lie to curry favor/collude with other officers) and to impeach Williams’s self-defense claim in the Barkley matter; the trial court limited cross-examination to the existence and general nature of the investigation but barred detailed questioning about the underlying facts.
- The court denied the defense’s requests for dismissal, mistrial, or a mid-trial continuance to investigate the newly disclosed material; Williams eventually testified and the jury convicted Smith on four firearm-related counts.
- On appeal, Smith argued: (1) the court violated his Sixth Amendment confrontation right by curtailing corruption-bias cross-examination; (2) the court improperly precluded impeachment on Williams’s allegedly false self-defense testimony; and (3) the government’s delayed disclosure of the IAD materials violated Brady and required reversal. The D.C. Court of Appeals affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the trial court violated the Sixth Amendment by precluding cross-examination to show "corruption bias" (willingness to lie) | Smith: court wrongly blocked cross-examination and extrinsic evidence showing Williams lied in a Gerstein affidavit and colluded with officers, depriving jury of key impeachment material | Gov't: defense failed to preserve a corruption-bias proffer; counsel mainly argued collusion bias; proffered inconsistencies were minor and speculative, not a well-reasoned suspicion of corruption | Affirmed: court did not err. Proffers showed only minor/inconsistent accounts of a chaotic event and failed to establish the requisite "well-reasoned suspicion" of corruption bias to justify extended inquiry. |
| Whether the court erred in barring impeachment of Williams for allegedly false assertions about acting in self-defense in the Barkley incident | Smith: Williams opened the door by asserting self-defense; defense should have been allowed to challenge that claim to impeach veracity | Gov't: allowing full inquiry would produce a distracting mini-trial; trial court allowed limited inquiry and jury heard that Williams faced an investigation | Affirmed: no reversible abuse of discretion. Court reasonably limited probing to avoid a mini-trial; speculative benefit of asking whether Barkley’s hands were "up" would likely not have altered outcome. |
| Whether the government's mid-trial, late disclosure of IAD materials violated Brady and required reversal (or at least a continuance) | Smith: untimely disclosure prevented adequate investigation and effective cross-examination of Williams; materiality satisfied because Williams was a key witness | Gov't: disclosure was made (though late); information was not material because it would not have produced a different outcome | Affirmed: court erred in denying a continuance but error was harmless under Brady materiality test — no reasonable probability the result would differ given total record (including Barkley trial materials). |
| Whether defense preserved and adequately proffered facts to support corruption-bias cross-examination | Smith: proffers (IAD report, differences with Gerstein affidavit, counsel’s information from Barkley’s attorney, possible videos) were sufficient to raise a well-reasoned suspicion | Gov't: proffers were speculative, conclusory, and focused on collusion rather than proof of corruption; insufficient foundation | Affirmed: proffers were too fuzzy/minor and contradicted by other IAD witnesses; not enough to warrant expanded corruption-bias inquiry. |
