Despite controversy surrounding the use of drones over U.S. territory, the U.S. Customs and Border Protection Agency has increasingly loaned drones over the last three years for tasks like spotting fishing violations, missing person searches, and inspecting levees on the Mississippi River, according to The New York Times.

Proponents of drones say the units are a valuable resource that provides an unmatched level of surveillance. But critics point out that monitoring individuals without probable cause or a warrant amounts to an invasion of privacy.

Flight logs show the FBI, the North Dakota National Guard, the Texas Department of Public Safety and the U.S. Forest Service have used the unmanned aerial vehicles in the past, but border agency says it has strict privacy policies governing use.
