Three drivers in San Jose, California, have filed a class-action lawsuit against the city and its police department over the deployment of nearly 500 Flock Safety cameras, alleging the system constitutes an unreasonable search and violates the Fourth Amendment. The suit, organized by the Institute for Justice, argues that the AI-powered license plate readers create vast, searchable databases of vehicle movements that law enforcement can access without warrants. Flock’s technology allows data sharing across agencies, raising privacy concerns about comprehensive tracking. San Jose recently voted to shorten data retention periods from one year to one month, but the lawsuit seeks to compel data deletion within 24 hours unless a warrant exists. Flock maintains its devices are constitutional, citing previous court rulings, though the Institute for Justice disputes these decisions and has appealed.
