Illinois
Illinois has no statewide mandate for county-level civilian oversight of sheriffs. Cook County is the only Illinois county with a chartered body whose statutory jurisdiction includes the independently elected Sheriff. All other Illinois counties rely on internal affairs offices and the state's Illinois Law Enforcement Training and Standards Board for decertification.
State context
The SAFE-T Act (Public Act 101-0652, 2021) is principally focused on pretrial detention reform, use-of-force standards, and a statewide officer misconduct database (50 ILCS 705/9.2) — not on civilian oversight structures. It does not require counties to create review boards. Chicago's COPA (Civilian Office of Police Accountability) is a City of Chicago body covering CPD only; it has no jurisdiction over the Cook County Sheriff.
