This was already settled by the Dredd Scott case before the SCOTUS.
http://en.wikipedia.org/wiki/Dred_Scott_v._Sandford#DecisionThe Court also presented a parade of horribles argument, based on the Privileges and Immunities Clause of Article IV, listing what the Court considered to be the inevitable and undesirable effects of granting Scott's petition:
It would give to persons of the negro race, ...the right to enter every other State whenever they pleased, ...to sojourn there as long as they pleased, to go where they pleased ...the full liberty of speech in public and in private upon all subjects upon which its own citizens might speak; to hold public meetings upon political affairs, and to keep and carry arms wherever they went. While the conclusion that blacks could not be citizens, or exercise the rights and privileges of citizens may have been over turned, the reasoning and stipulation of those rights and privileges has never been questioned.
Therefore, the SCOTUS has already affirmed that the ownership, and carrying of arms is an inherent right of citizenship.
This is one of those times I miss FQ's daily presence.
