As President Trump's immigration enforcement crackdown has intensified, at least 30 U.S. cities including Flagstaff, Arizona; Cambridge, Massachusetts; Eugene, Oregon; and Santa Cruz, California have deactivated or canceled contracts with Flock Safety, an Atlanta-based company operating automatic license plate readers across more than 5,000 law enforcement agencies nationwide. Cities discovered their local data was being shared with federal agencies including U.S. Border Patrol, U.S. Customs and Border Protection, and Homeland Security Investigations without explicit local authorization, raising concerns about potential use in deportation enforcement and violating state laws. Flock's CEO characterized critics as "terroristic" and framed the cancellations as a "coordinated attack" by activists seeking to "defund the police," but local officials and residents countered that questioning surveillance technology and demanding transparency constitutes legitimate democratic participation.
