Inside an armored vehicle, an Army scout uses a joystick to direct a long-range optical scope toward a man perched atop the U.S.-Mexico border wall cutting across the hills of this Arizona frontier community.
The man lowers himself toward U.S. soil between coils of concertina wire. Shouts ring out, an alert is sounded and a U.S. Border Patrol SUV races toward the wall — warning enough to send the man scrambling back over it, disappearing into Mexico.
