I'm all for drone's used to gather intelligence or surveillance. But there are many problems by arming them on US territory. They can be, and have been, hacked. Somebody would be able to send an armed drone crashing down onto innocent civilians. It also takes away "due process". What gives the military or government the right to be judge and jury from the skies? For the current record of drones strikes, what is the success rate? How many times did they miss their target or cause collateral damage? A lot of things could go wrong when lives are at stake from a bomb being operated by remote control.
