Think about this the next time you see that drone over the football game you are attending. Wonder what all the hoopla is over "Drones" in the USA? Take a look at the video link below and watch it in full-screen. Russian dude has created a remotely controlled quadroto-copter fitted out with a 100 round machine gun. Watch him as he has fun blowing up mannequins and cars. It's all done with a touch of humor, but the reality is that this fellow has created a very lethal killing machine that could be remotely controlled and come into your yard, or house and kill everyone there. Then it can fly away or be self-destructed. These types of robots have so much 'stealth' killing power, populations of the near future have a reason to be worried about what can happen to them over a Sunday Bar-B-Q.
