Flock cameras are quickly becoming a new front in the war on drugs. Flock describes its automated license plate readers as cameras that record license plates, vehicle characteristics, locations and timestamps, converting those observations into searchable data. Supporters will argue that license plate readers help recover stolen vehicles, find missing people and identify suspects in violent crimes. Cannabis reform organizations should therefore oppose new Flock contracts, demand that existing contracts be terminated and support legislation requiring warrants before police may search historical license plate information. Flock cameras are not merely traffic technology.
