Kind of hard to explain, but your average LEO, Judge, etc wouldn't see the NFA as being unconstitutional (even though it is, and I can't think of anyone who would try to press that issue and bring up to the SCOTUS)... but sure, there are a lot of laws that infringe upon the constitution (NDAA, Patriot Act, etc), but where is the line drawn? With most "sport/hunting" gun owners (IE: the ones who are dumb enough to think that's the intent of 2A) they'll only take so much- they're fine with NFA, they're okay with '86 ban, etc... but when you talk about an all out ban, your average Joe, John Law, and Sheriff Bob will say "Okay, that's too far!" It's already floating around that a lot of Dems in Congress oppose Fecalstein's proposals, of course that's not saying that the average, ignorant gun owning public won't go along with some grandfather clause AWB or Capacity restrictions, but an all out ban and confiscation won't fly.
