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.
