Modifies provisions relating to civilian review boards

HB 1186 standardizes the structure and authority of civilian review boards for police misconduct investigations in cities with fewer than 125,000 residents. It requires these boards to investigate specific complaints about excessive force, abuse of authority, or discriminatory language (including slurs), but prohibits findings based solely on unsworn complaints or unsubstantiated prior allegations. The bill explicitly limits boards to these defined powers, voiding any broader authority granted by local governments, and mandates that all findings be submitted to the chief law enforcement official. Cities with populations between 125,000 and 160,000 are exempt from these rules and may establish their own oversight entities with different powers.
