The United States Customs and Border Protection (CBP) is now patrolling half of the US-Mexico border with drones, according to a new report by the Associated Press.
According to two anonymous sources from within the CBP, Predator B drones fly over remote areas with “a high-resolution video camera and return within three days for another video in the same spot.” Then, those videos are compared to see if there was any difference—footprints, livestock tracks, or vehicle trails.
Agents have found that most of the time, nothing has changed.

False alarms were reported for four percent of the missions, while two percent of missions were inconclusive.
