United States v. Brown
299 F. Supp. 3d 976
E.D. Ill.2018Background
- ATF conducted "false stash house" sting operations (2006–2013) in Chicago, presenting undercover opportunities to rob fictional drug stash houses; 94 defendants were charged across 24 operations.
- Defendants (including Brown and Williams) moved to dismiss indictments, alleging selective enforcement/racial profiling because stash-house defendants were disproportionately non-white compared to the local population.
- Court appointed defense expert Prof. Jeffrey Fagan (statistical analysis) and the government retained Prof. Max Schanzenbach as rebuttal; both testified at a multi-day evidentiary hearing.
- Fagan concluded the racial composition of defendants showed a statistically significant anomaly; Schanzenbach challenged Fagan’s comparison group, independence assumptions, and clustering.
- The central legal question: whether law-enforcement conduct in designing/operating the stings violated the Fifth Amendment’s equal-protection component (selective enforcement/prosecution), requiring dismissal of indictments.
Issues
| Issue | Plaintiff's Argument (Defendants) | Defendant's Argument (Government) | Held |
|---|---|---|---|
| Standard of proof for selective enforcement dismissal | Defendants: preponderance should suffice | Gov't: Armstrong/"clear evidence" standard applies | Court: requires "clear evidence" due to deference to executive discretion; Armstrong standard applied |
| Admissibility/weight of expert statistical evidence | Fagan: data show discriminatory effect and intent | Schanzenbach: Fagan's comparison group and independence assumptions flawed; testimony challenge goes to weight | Court: both experts admissible under Daubert; reliability contested but for weight |
| Discriminatory effect (do stats show ATF targeted on race?) | Fagan: 78.7% black defendants vs smaller black share in "potential eligibles" → statistical anomaly | Gov't + Schanzenbach: comparison group too broad; many defendants recruited by initial targets (not ATF); clustering/independence problems; geographic and recency issues | Court: defendants failed to prove discriminatory effect—Fagan's assumptions (ATF "selected" all 94; independence; broad pool) undermine reliability |
| Discriminatory intent (did decisionmakers act because of race?) | Defendants: agent comments and departures from ATF protocols show purposeful discrimination | Gov't: agent remarks contextual and tactical; ATF largely followed criteria; many defendants were viable targets by criminal history/statements | Court: insufficient non-statistical evidence of discriminatory purpose; agent comments and protocol deviations do not show decisionmakers acted at least in part because of race; motions denied |
