FBI Fesses Up: We’ve Used Domestic Drones 10 Times
In none of these cases, the bureau says, did it apply for a warrant to conduct the drone surveillance. The letter states that the FBI will seek a warrant when using a drone only if it is attempting "to acquire information in which individuals have reasonable expectations of privacy under the Fourth Amendment." But it does not clarify exactly what kind of information it believes individuals have a reasonable expectation of privacy over. Paul has requested that the FBI provide more details, saying he is concerned that the bureau may be adopting an “overbroad” interpretation of the rules in order to conduct warrantless surveillance.
But don't worry, the FBI promises they weren't armed.
