As has been pointed out a gun is incapable of killing anyone under most circumstances. People kill people etc. What a gun does is provide the average person with a remarkable increase in lethality. I have never fired a gun, the only gun I have even held is and non functioning family heirloom rifle. If you hand me a pistol I am still far more dangerous than I was unarmed, and quite a bit more dangerous than I would be with a simple edged weapon.
So while guns don't kill people, the brutal efficency with which they alow those weilding them to kill people is frightening.
Yep, I think we should ban people instead of guns.
Actually, I would privatize the cops and require everyone over the age of 13 to be armed.
