During the recent spate of “sightings,” various U.S. officials supported shooting down drones found flying in U.S. airspace. New Jersey representatives were apparently “the first to call for the drones to be shot down.” Federal elected officials also demanded action. Sen. Richard Blumenthal (D-Conn.) said that authorities should “take them out of the skies, especially if they’re flying over airports or military bases.” President Trump and Rep. Marjorie Taylor Greene (R-Ga.) similarly suggested that the drones be shot down. Various actors have floated different options for actually engaging drones, ranging from the use of directed energy systems to signal interruption to physical nets.

What authorities to immobilize drones do U.S. federal, state, and local officials currently have, and—assuming Americans want at least some of those actors to have that authority—where are the gaps?
