And isn't it even more ironic that the justification for the federal and various state AWB's is that the banned weapons are "weapons of war?" If anything, Miller protects them (even if semi-auto) far more than so-called "sporting guns"). Further irony occurs when the same people cite Miller as being a justification for gun control, and specifically an AWB. This last bit shows that they either haven't read the case, that their reading comprehension is at about the level of my non-reading 3-year-old or that they're just a bunch of lying sacks of $hit.
Period. End of story. "Living document" types need not respond. And don't anyone get us off on some idiot straw man about NBC weapons either. That dog don't hunt. Never has.
I think you hit the nail on the head with #3!!!!!
That's my guess.
