I'd be more worried about the "down with the state" loonies or one of their followers doing this than the government. With the government, you have a chance to see what's coming. You almost never find out about the whacko who saved up, bought a gun and shot up a school until it's too late. Is it possible that the government might, in some way, turn on it's citizens? Sure, if it can be justified as "for the children" or "fighting terror" or any number of inane excuses. My guess, though, is that it will be a civilian with a drone and grandiose dreams of "liberating America from it's oppressors" who will make our fears of drones a real thing.
