Brown v. City of Chicago (CA7) (here):
Arthur Brown sued Officer Duane Blackman under 42 U.S.C. § 1983 for excessive force, alleging Officer Blackman shot him without justification. The district court granted Officer Blackman summary judgment, concluding that because Brown had been convicted of aggravated assault, aggravated unlawful use of a weapon, and unlawful possession of a weapon by a felon based on his encounter with Officer Blackman, Brown’s current suit was barred by collateral estoppel. Brown appeals. We affirm.
