"Regulate, historically means facilitate. Therefore, the Congress of these United States was to be the facilitator of commerce between the states and the tribes."
It's backed by this cite:
"Black’s Law Dictionary, regulate meant that Congress should in principle assist with Commerce disputes between the States, but did not grant Congress the power of law to inflict criminal penalties, Article 2 of the Kentucky Resolutions of 1798 by Thomas Jefferson."
H'mmm, "A well-facilitated militia," then? In-ter-est-ing. So, if McDonald goes our way and there were also to be a proper understanding of the meaning of "militia," probably requiring the Supremes to ring in, does that mean all the able-bodied males of military age, at least, will have their militia aspirations facilitated by Congress?
Toss them eggs in the chicken-counter! Don't hold your breath. Still, one can dream.
On a sobering note, same article cites the reason I think Andrew Jackson was a sonva-B (albeit a tough one), Worcester v. Georgia. YMMV. --But there's plenty of jurisdictions now where, prejudice-wise, you'd be way better off bein' Cherokee than a gun-owner. MA, for instance, which is where this wander started. Bear it in mind.
