It doesn't have to be "desperate and evil people" who make their own weapons. YouTube or Google Cody Wilson and 'ghostgunner.'
He and his team have made distributed online plans for guns made out of plastic. Now they have produced a milling machine that you can order, set up at home, and use their plans and program to mill metal parts for your own un-traceable semiautomatic rifle or handgun. I'm not saying that is bad, I think it is great that people are taking steps to make the type of "gun control" that leftists want impossible. The idea of "doing away with firearms" is impossible and just political rhetoric.
