Mac Muir returned to his hometown of Oakland in 2023 to run the city's civilian police watchdog. However, it was a tough time for the Police Commission. The Community Police Review Agency, which operates under the authority of the Police Commission, had become overwhelmed with pending cases and enormous expectations and was struggling with too few staff. Muir spent two years rebuilding the agency, hiring investigators, developing a new case management system, cleaning the case backlog, and managing high-profile reviews of police misconduct.
