United States of America: Governor of California signed Bill on Law Enforcement Agencies and Artificial Intelligence (SB 524)

On 10 October 2025, the Governor of California signed Senate Bill 524 on law enforcement agencies and artificial intelligence into law, establishing Section 13663 of the Penal Code. The law governs the use of artificial intelligence by law enforcement agencies and their contracted vendors. It defines “contracted vendor” as a third party providing artificial intelligence systems to assist in generating draft police reports and prohibits any vendor from sharing, selling, or otherwise using law enforcement data except for the contracting agency’s purposes or under a court order. Vendors may only use the data for troubleshooting, bias mitigation, accuracy improvement, or system refinement. Law enforcement agencies must ensure that all reports prepared with artificial intelligence contain a disclosure statement and officer signature, that the first draft is retained, and that an audit trail identifies the user, data, and media involved in report creation.
