Unfortunately I don't know if it the the government we need to worry about. We assume that the military will be the one to implement this... drone technology is very cheap now (relatively) and so are image recognition systems. A rouge / non-state organization could easily and relatively cheaply create automated turrets and automated drones. Heck, Youtube has tons of videos of Americans doing it in their backyard just for "fun". Would they be as good as a state military's $10MM drone? Probably not. But when you can build 10k of them from the price of one, who cares? Really we should be worried about both.
