A secretive US Border Patrol program is monitoring millions of American drivers with hidden cameras disguised as traffic safety equipment to scan license plates and track travel patterns. This program has expanded beyond the border zone into major metropolitan areas, involving entities like the Drug Enforcement Administration and private companies such as Rekor, Vigilant Solutions, and Flock Safety. It raises constitutional concerns about privacy rights due to covert surveillance, aggressive law enforcement stops, and the use of AI to build extensive databases on drivers' activities.
