Sean A. Grady v. United States
180 A.3d 652
D.C.2018Background
- On October 27, 2014, MPD Officer De los Santos followed Sean Grady after a domestic-incident call; De los Santos observed Grady appear anxious, fumble in his coat pocket, and then heard a heavy object hit the ground. A handgun was found at that spot; Grady was arrested and marijuana was found on him.
- Grady was tried and convicted of carrying a pistol without a license and unlawful possession of marijuana; several other firearm-related counts were tried and resulted in acquittal.
- At trial Grady sought to introduce neighborhood gun-crime statistics (PSA 304, 2010–2014) to support a theory that the gun might have been discarded by someone else; the defense served subpoenas duces tecum on MPD for those statistics the morning of trial.
- The trial court quashed the subpoenas as overbroad and potentially inadmissible and later limited cross-examination by precluding questions of Officer De los Santos about gun-crime rates in PSA 304, finding the proposed evidence irrelevant, prejudicial, and likely to invite speculation.
- Grady appealed, arguing the subpoenas were wrongly quashed (violating Super. Ct. Crim. R. 17 and the Compulsory Process Clause) and that exclusion of the cross-examination violated his Sixth Amendment Confrontation rights.
- The D.C. Court of Appeals affirmed, holding the subpoena rulings were not an abuse of discretion and that limits on cross-examination were proper because the statistical evidence was not sufficiently probative and risked juror speculation.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the subpoenas duces tecum seeking MPD gun-crime statistics were improperly quashed | Grady: statistics were evidentiary, relevant, central to defense; MPD can produce data so burden is minimal | Government: subpoenas were untimely, overbroad, irrelevant, and unduly burdensome | Court: quash affirmed — subpoena was overbroad, vague, and defendant failed to narrowly tailor or justify necessity |
| Whether preclusion of cross-examining Officer De los Santos about gun-crime rates violated the Sixth Amendment Confrontation Clause | Grady: questioning on neighborhood gun-crime rates was highly probative to show another person may have left the gun and would mitigate officer testimony | Government: such statistics would be speculative, not tied to the specific incident, and more prejudicial than probative | Court: exclusion affirmed — trial court reasonably limited cross-examination; statistics would invite speculation and were not sufficiently probative |
