12 guys killed 3000 people with nothing but box cutters. Obviously we need less boxcutters as well.
I dont really think people that like guns are the problem though. I would not classify myself as someone that "likes" guns. On the other hand i know people that "like" guns, and it's not that they likes the power a gun has, but they certainly understand and respect it, and therefore take extra care. They like them because they appreciate them for the same reason that people appreciate works of art, or sportscars. For the Craftsmanship, for the minior details that went into the design of the gun, for the historical value of the gun.
