The California Law Enforcement Telecommunications System (CLETS) is the computer network that connects public safety agencies across the state to criminal histories, driver records, and other databases. Since 2014, EFF has served as a watchdog for this system, drawing attention to open meetings violations, attempts to integrate face recognition technology, and failures by the California Attorney General's Office to enforce regulations around misuse. 

In 2018, the California Attorney General's Office announced an overhaul of the oversight process, resulting in for the first time the release of near-comprehensive data on when police officers inappropriately access data on California residents.
