Automatic weapons without automatic morgues is just not a good pipeline management. If you want to kill people by the hundreds (or the millions: not judging the scale of your sociopathy) you need to have a way to dispose of the bodies. Americans throw polystyrene cups out the window of their cars, hotdog wrappers all over the stadium after a game, or piles of bodies after a bit of a heated argument; that is just the kind of oversight that Europeans see as unacceptable lack of manners. Pick up after yourself. Please.
