WASHINGTON -- FBI Director Robert Mueller acknowledged Wednesday that the bureau has used unmanned aerial drones for surveillance in the United States and suggested that government needs to develop guidelines as their use grows.
Testifying before the Senate Judiciary Committee, Mueller said the bureau has employed drones in a very, very minimal way and very seldom.
I will tell you that our footprint is very small, he said, responding to a question by Sen. Charles Grassley, R-Iowa. We have very few and have limited use, and were exploring not only the use but also the necessary guidelines for that use.
Muellers comments come amid a growing public debate over privacy and civil liberties spurred by the recent revelation of the National Security Agencys massive telephone and Internet surveillance program.
Chris Calabrese, legislative counsel for the American Civil Liberties Union, called Muellers acknowledgement disturbing. Jim Harper, director for information policy studies at the libertarian-leaning Cato Institute, said that domestic surveillance drone use raises Fourth Amendment search and seizure questions.
I think its something that the FBI has started to use these drones without any clear policy to protect our privacy, Calabrese said. Now we have cheap, easily accessible technology to allow law enforcement to spy on us. Law enforcement should only use these drones if they have probable cause.
Sen. Dianne Feinstein, D-Calif., the Senate intelligence committee chair who supports the NSA surveillance programs, echoed Calabreses concerns.
If people are concerned about privacy, I think the greatest threat to privacy of Americans is the drone and the use of the drone, and the very few guidelines that are on it today and the booming industry of commercial drones, she said.
Sen. Mazie Hirono, D-Hawaii, told Mueller that these drones can be very, very tiny but store a lot of data and there could be cameras on it.
In March, Sen. Rand Paul, R-Ky., waged a 13-hour filibuster railing against CIA Director John Brennans nomination in which he warned of increasing government use of aerial drones on U.S. soil.
After his filibuster ended, Paul received a letter from Attorney General Eric Holder stating that President Barack Obama doesnt have the power to use a weaponized drone to kill an American not engaged in combat on American soil.
