Of course the SC disagrees, it’s utter insanity to allow people to freely own fully automatic weapons.
The question is, whether or not banning them violates the letter of the 2nd amendment, and there’s no possible reading of the actual words of the amendment that allows for the banning of military grade weaponry.
It mentions the importance of the Militia, a military organization, the security of the State, and the importance of people owning arms to achieve that goal. How you get from that to allowing a complete ban on ALL military grade armament, is beyond me. Even the Miller case mentions (incorrectly) the lack of military use for a sawed off shotgun as a reason the ban was constitutional.
The only reason the SC would uphold the law is that it is insanity to overturn it. It has nothing whatsoever to do with constitutionality.
We all admit up front that allowing people to freely own fully automatic weapons is lunacy, the only question is why we haven’t all admitted to ourselves that it applies to semi-automatic weapons as well.
