Generally, speaking, any weapon can be characterized as an "assault" weapon if you injure someone.
But these guns that they're using now, like the one the guy had in Las Vegas to just lean out his window and take down dozens of people per minute, why does anyone need to own a weapon like that? Even the people who enjoy to go hunting, if they used a weapon like that, whatever animal they're hunting for would have like 60 bullet holes are something, that type of weapon is "overkill" for hunters. I think only if you're on the front line in Kabul or something should weapons like that be used.
