It would be a tremedous ruling in favor of our rights at a Federal level. I'm wondering though, I had heard that this still enables individual states to maintain such constraints on firearms as they see fit, to the point of yet again infringing upon our rights. I wonder exactly how far they can go at a state level say, in a place like Californistan?
For one thing, the people in the states retain the rights, not the state itself. Secondly, if the state wants to remain as part of the Republic, it must also follow the guidelines set forth in the Constitution. By arguing that "States" have the right to infringe on firearms ownership, then the states could also say, ban printing presses and conduct door to door searches or waive trial by jury. Californistan, as you call it, is what happens when communism takes over.
