Why doesn’t the U.S. just shoot down drones? To stop drone incursions, the U.S. must first “have the capability to detect, track, identify, make sure it’s not a civilian airplane flying around,” says retired U.S. Air Force Gen. Glen D. VanHerck. “Then it becomes a safety issue for the American public. Firing missiles in our homeland is not taken lightly.” #60Minutes #drones #usdefense
