From Paul Bedard, writing in the Washington Examiner:
The Secret Service is facing a “grave” threat to President Trump from a new wave of high-tech weapons including armed drones, plastic guns made on 3-D printers and even sophisticated IEDs, according to a new alert issued by a former agent.
“This threat is grave,” Dan Bongino told Secrets. The author of a new book on the Secret Service that calls for a seismic change of thinking at the agency, Bongino said terrorists are eager to unleash an attack on their “ultimate prize.”
New age threats include weaponized drones delivered in “swarms” that could attack the White House or any place the president is. The problem, he explained, is that the agency’s agents and Uniformed Division are trained mostly to stop ground attacks.
He said that terrorists have looked at drones “for a long time,” and that “the real threat comes from the more spectacular swarm attacks.”
