FBI uses drones in U.S., says Mueller – CNN Security Clearance - CNN.com Blogs: FBI Director Robert Mueller acknowledged the law enforcement agency uses drone aircraft in the United States for surveillance in certain difficult cases.
Mueller told the Senate Judiciary Committee on Wednesday that drones are used by the FBI in a "very, very minimal way and very seldom."
He did not say how many unmanned surveillance vehicles (UAVs) the FBI has or how often they have been used.
But a law enforcement official told CNN the FBI has used them a little more than a dozen times but did not say when that started. The official said drones are useful in hostage and barricade situations because they operate more quietly and are less visible than traditional aircraft such as helicopters.
