By that logic, we should ban cars, right? In societies with lots of cars like the U.S., there are a lot of car accidents.
Not to mention all the people that don't wear seatbelts, speed, drive intoxicated (i.e., alcohol, marijuana, etc.), etc.
Oh, and we should ban spoons while we're at it. They make people fat.

Look, when I say I don't really care about gun ownership, I mean I really don't care. I want people to be able to own them though. People like you and me to whom it has never occurred to shoot someone shouldn't have to suffer the consequences of others' actions.
