I understand guns don't kill people, people kill people, but guns make it much easier. You stand a better chance at defending yourself against a knife. Do you think as many mass killings could happen where one or two people kill multiple people, if they didn't have guns? The person is making the choice to kill, but they are using the gun, an efficient and effective weapon, to do it. If guns were completely banned, yes there would still be guns out there but a lot fewer, and it would be more difficult for people to get them, resulting in less gun deaths.
