The Federal Aviation Administration has allowed several police departments to use drones across the U.S. They are controlled from a remote location and use infrared sensors and high-resolution cameras.

Chief Deputy Randy McDaniel of the Montgomery County Sheriff’s Office in Texas told The Daily that his department is considering using rubber bullets and tear gas on its drone.

“Those are things that law enforcement utilizes day in and day out and in certain situations it might be advantageous to have this type of system on the UAV (unmanned aerial vehicle),” McDaniel told The Daily.

The use of potential force from drones has raised the ire of the American Civil Liberties Union.
