> Importantly, the definition of “public agency” is limited to state or local agencies, including law enforcement agencies, and does not include out-of-state or federal law enforcement agencies. (See Civ. Information Bulletin 2023-DLE-06 California Automated License Plate Reader Data Guidance Page 3 Code, § 1798.90.5, subd. (f).) Accordingly, SB 34 does not permit California LEAs to share ALPR information with private entities or out-of-state or federal agencies, including out-of-state and federal law enforcement agencies. This prohibition applies to ALPR database(s) that LEAs access through private or public vendors who maintain ALPR information collected from multiple databases and/or public agencies.
OPD or other California state agencies may have broken the law but Flock is working exactly as intended.
