The issue is "banning" something which those versed in the art know is impossible to ban -- thereby only removing it from the law abiding, and not from the abusers of said item. (proof: Research how cartels get weapons produced under such a "ban". TL;DR: Trivially, by contract engineers w/ basic modern milling machinery.) Frightened, ignorant (of the state of the art) people are led to believe "banning" is helping them "making them safe", when instead it is harming them: nobody law-abiding remains to come to their aid, while abusers and thugs wield powerful weapons, unopposed. Instead, benighted government officials ban common farmer livestock varmint rifles by the hundreds of thousands (see: Canada, just now). So, no -- if someone wants to ban something, then they should darn well consult with anyone who knows something about that item, to see if A) it makes sense, and B) if it will actually prevent the violent from obtaining/using it.
