Hundreds of law enforcement agencies outside the state have access to Flock data from Flock license plate cameras and Illinois readers. CHICAGO — An automatic license plate reader company used by hundreds of police departments around Illinois broke state law by allowing federal border enforcement officers to access Illinois license plate camera data, according to Illinois Secretary of State Alexi Giannoulias. The company, Flock Safety, was also allegedly used by out-of-state police earlier this year to look for a woman who recently had an abortion. License plate readers are cameras which can automatically detect the license plate, make, model and other details of cars while they’re driving. These out-of-state agencies that have access to Illinois license plate data include police departments, universities and state agencies.
