Using the same logic in the majority opinion, i.e., the right to bear arms existed prior to the Constitution, and realizing that the District of Columnbia was once part of Virginia and Maryland prior to being created, then the right to bear arms still belongs to the residents of D.C. despite the fact it is not a state. The minority idiot judge was grasping at straws with her opinion, IMO.
It isn't even logical. There would be no DC circuit if the constitution didn't apply.
This dumb broad probably thinks the constitution applies to Gitmo prisoners but not DC residents. I'm not joking.
