Wonderful. A latter-day Patrick Henry. :)
Somewhere along the line my original point and yours were conflated. The issue isn't whether the rebellion can be put down. The issue is whether, if there is no regulation, the gun's obsolescence will render the 2nd amendment ineffectual.
Ah, but then we come back to the "whether arms = guns" debate. Again, I'll stick to the idea that "we" retain the right to own the same basic "implements of destruction" that the common foot-soldier may carry. With my little verbal gyration, obsolescence is moot... unless the common footsoldier will one day walk around unarmed.
