'Biggest dilemma' in homeland counter drone strategy is 'how broad the threat exists'

The federal government, in conjunction with state and local governments, is desperately trying to catch up to the threat posed by drones, but needs to close the gap for U.S. defenses before it’s too late.

The sheer scope and scale of what’s needed is hard to quantify. Any public event, airport, airplane, military installation, or critical infrastructure could be targeted by a drone or drone swarms, and the U.S. needs to be prepared to not only stop the perceived threat, but do so in a way that avoids collateral damage.
