From Roll Call:
Customs and Border Protection drones operated along U.S. borders and coasts 80 percent of the time over the last three years — but strayed 20 percent of the time into restricted airspace due to things like malfunctions, or else entered into Federal Aviation Administration-approved airspace for things like disaster missions. That’s according to the Government Accountability Office, which also found that the Department of Homeland Security’s CBP has put in place procedures for complying with civil liberties and privacy laws and standards.
