You said it better than me. The right to possess isn't regulated. The use is regulated by state law and local ordinance. I believe Marauder was eluding to the 14th amendment which is another discussion. The right to keep and bear arms was already a right in the state constitutions. Another discussion in an erroneous power grab by the supreme court.<quoted text>
Allow me to say that what you're speaking of is that matter of 'ordnance,' wherein the right itself isn't being regulated, but in fact what is being regulated is the activity.
A good common sense ordinance would of necessity state that discharging a gun in a thickly settled area, without regard to the possible harm it might cause, is forbidden, unless the act is conducted in self-defense.
In that case, which I state above, the right isn't regulated in and of itself. The ordinance is a demand that right be exercised responsibly.
Federal constitutional law is limited to regulation of commerce. There shouldn't be any federal laws pertaining to possession. Another court case down the road, I suppose.
