Multiple U.S. cities are canceling contracts with surveillance vendor Flock Safety, citing fears that its national network of automated license plate readers (ALPRs) shares data with federal agencies like ICE. Local officials argue this surveillance disproportionately threatens immigrants and communities of color, turning municipal tools into instruments of federal overreach. The controversy centers on Flock’s data-sharing model, which critics call an uncontrollable, for-profit surveillance system built on misunderstood local consent. Flock defends its system, claiming data sharing is opt-in and that the small number of cancellations sacrifices a proven crime-fighting tool. The company blames local officials for not understanding the terms they agreed to, while cities accuse the company of a lack of transparency and breaking trust, particularly after a pilot program with DHS was revealed.
