I've owned guns all of my adult life and they have not hurt a single human.  Where do I buy the guns that hurt or kill humans without a HUMAN operator?  The evil you speak of is in the human not the machine. I would guess that cars kill more humans per year in Oregon than guns do . Can we ban them? I don't loose my rights because of the action of others. If that is how our rights were distributed nobody would be allowed to speak.
