I think its crazy too.But the whole gun rights debate in the US just looks totally mad from a European perspective.
Tell you the truth I can't get worked up on Universal Background checks. That would be what I would call a baby step. But what we need is Sweeping Changes. and we need them like 20 (or maybe 40) years ago.
So you know how Americans respond to mass shootings? they go to the gun store and buy guns. Just in case this time someone actually passes a gun control law.
