The entire NFA, in its entirety, MUST be repealed. "Shall not be infringed" is pretty damned clear.
Read the decision in US v. Miller,
"
In the absence of any evidence tending to show that possession or use of a 'shotgun having a barrel of less than eighteen inches in length' at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia,
we cannot say that the Second Amendmentguarantees the right to keep and bear such an instrument. Certainly it is not within judicial notice that this weapon is any part of the ordinary military equipment or that its use could contribute to the common defense."
and,
"A body of citizens enrolled for military discipline.' And further, that ordinarily
when called for service these men were expected to appear bearing arms supplied by themselves and
of the kind in common use at the time."
In the Miller case, no one was there to argue for the defense. If someone had shown that a short barreled shotgun was an arm of military utility, the Court would have said, "...
the Second Amendment guarantees the right to keep and bear such an instrument."
The second Amendment SPECIFICALLY protects the right to own military grade weapons! Read the above in context. In "common use" by whom? One might interpret this phrase to equate to "...of the kind typically used at the time". Typically used for military service! I say again, "
these men were expected to appear bearing arms supplied by themselves". The militia is required to show up for service bearing military arms supplied by themselves! We, as Americans are required, duty bound, to possess arms of military utility.
Your fine Weatherby hunting rifle worth $3000-5000, might not be protected by the Second Amendment, but your M-16 and you BAR most certainly are!
This is the supreme law of the land!
Jeepers... you think the enforcers at AFT (Sleepy Joe's words) just don't know?
