Despite that, its a dangerous thing to happen. I am aware of how unlikely it is for the current US Government to use the drone offensively, but once you have a massive fleet of drones flying over the US, patrolling "troubling" neighborhoods constantly, the temptation to use those abilities rises significantly.
I hope that Congress takes action to outlaw this practice, but I have little faith it will happen. It seems like everyday the country is falling further into the pit of becoming an authoritarian police state.
I've been saying for ages that these overseas actions are proving grounds for testing malicious tech - for it's eventual deployment against US citizens.
