Drones are a 'real threat,' but U.S. doesn't know how many are out there
/WASHINGTON — The Department of Homeland Security is beefing up its anti-drone efforts away from the country's borders as it takes aim at potential national security threats.
The dangers posed by explosives-laden drones were underscored last year by an assassination attempt targeting Venezuelan President Nicolas Maduro as he made a speech. The FBI has also warned that it expects terrorist groups to attempt to use drones to carry out attacks on American soil.
"In the wrong hands, they're a real threat," said Tim Bennett, who oversees counter-drone technologies at the DHS.
