Police departments and officials from Border Patrol used Flocks automatic license plate reader (ALPR) cameras to monitor protests hundreds of times around the country during the last year, including No Kings protests in June and October, according to data obtained by the Electronic Frontier Foundation (EFF).The data provides the clearest picture yet of how cops widely use Flock to monitor protesters. In June, 404 Media reported cops in California used Flock to track what it described as an immigration protest. The new data shows more than 50 federal, state, and local law enforcement ran hundreds of searches in connection with protest activity, according to the EFF.
