Isn't the NFA based on the wishes of the people back in 1934? They were tired of all the gangster violence (drive-by shootings with Tommy guns and sawed-off shotguns, etc.) and wanted something done about it. If I've got this right (and I'm not saying that I do) then, with all due respect, why are we blaming the Government for something we wanted?
Life is tough. It's tougher if you're stupid.
