Without him knowing, this guy perfectly illustrates the real gun problem in this country - gun obsessiveness.
You bring up a good point, but this conversation could be taken a step further and shift our focus from guns to 3D printing, and an open source world in general. I do agree that Americans have an obsession with guns. We romanticize them. I have a friend who has three guns. Another who just recently bought a revolver, and another who also purchased a compact semi-auto pistol. All they do is clean their guns, they don't even take them out to the range, claiming that ammo is expensive. Well, it is! A gun is a tool, not a toy, and these boys don't have the heart, the skill, or the head to kill another human. These guns are sitting as "collectors" items, hardly being fired. I'm split in the gun debate. On the one hand, there are WAY too many out there, but on the other, I'd rather not face the end of a barrel without having one myself. This is America, after all.
