United States of America: California State Legislature adopted Bill on Law Enforcement Agencies and Artificial Intelligence (SB 524)

On 10 September 2025, the California State Legislature adopted Senate Bill 524 on law enforcement agencies and artificial intelligence, adding Section 13663 to the Penal Code to regulate the use of artificial intelligence by law enforcement agencies and their contracted vendors. The law defines “contracted vendor” as a third party providing artificial intelligence tools for creating draft police reports and prohibits vendors from sharing, selling, or repurposing information processed for law enforcement purposes except for the contracting agency’s purposes or under a court order. Vendors may only access such data for troubleshooting, bias mitigation, accuracy improvement, or system refinement. Each law enforcement agency must ensure that reports generated using artificial intelligence include a disclosure statement and officer signature, that the first draft is retained, and that an audit trail identifies the user, data, and media used in report preparation.
