In Southern Arizona, since 2014, Israeli weapons giant Elbit Systems has installed a network of 53 surveillance towers up to 160 feet tall, employing a 7.5-mile camera range and 13-mile radius of ground-sweeping radar. These instruments of human control expand a layered system of U.S. border militarization made up of physical barriers, high-tech security, and armored patrols. This system violates the rights of indigenous Hia Ced O’odham and Tohono O’odham citizens, kills migrants, and represses freedom of expression.
