In my humble opinion it's a person problem, not a gun problem. Remove the gun, and you have a bomber, or a person who drives a truck into a crowded group of folks. Both of these examples have happened in the US, and recently. Go to Europe where guns are banned and you have a much hire occurrence of the bombings, and the people driving cars into people, and even stabbings (England was thinking of banning knifes for cripes sake). The problem is people need help, and I am all for getting them help, but sadly there will still be a few who wont take it.
And don't even get me started on the games and shows that people let kids watch and play that do nothing but diminish the value of a human life by turning it into a game.
