“The FBI uses drones for domestic surveillance purposes, the head of the agency told Congress. Robert Mueller confirmed to lawmakers that the FBI owns several unmanned aerial vehicles, but has not adopted any strict policies or guidelines yet to govern the use of the controversial aircraft. Mueller said the FBI has and will continue to weigh the possibility of publishing more information about its spy habits, but warned that doing such would be to the advantage of America’s enemies. ‘There is a price to be paid for that transparency,’ Mueller said. ‘I certainly think it would be educating our adversaries as to what our capabilities are.’”
