FBI Surveillance Drones

The FBI is looking to step up its use of surveillance drones. 

However, the agency is still developing policies for the unmanned aircraft. FBI Director Robert Mueller told a Senate panel that the chief issues are privacy and safely operating drones in densely populated areas. Drones have been used to look at stationary subjects to date and they were used at night during a hostage standoff earlier this year in Alabama, Mueller said. Each deployment requires permission from the FAA.
