Flock, an automatic license plate reader (ALPR) company, has restricted access to its camera network for U.S. agencies in California, Illinois, and Virginia. This decision follows reports by 404 Media highlighting instances where ALPR data was used in ways that raised privacy concerns, specifically lookups potentially related to Immigration and Customs Enforcement (ICE) and an abortion case. The move also coincides with new legislation impacting ALPR data usage in these states. Flock's action aims to address concerns about potential misuse of its technology and ensure compliance with evolving privacy regulations.
