Yes, the SC decision might affect state and local laws, but it's a federal court decision on part of the US Constitution.
I said this:
"We’re already subject to a collectivist interpretation of the 2A, unless we live in the DC District or the 5th Circuit. That means that the 2A does exactly nothing for an individual like me. How is that going to get worse?"
And I'm still waiting for an answer. Pointing out that cities and states have their own gun laws is unrelated. The thread, and my post, are about the 2nd amendment and how it is interpreted. My point is, the 2A doesn't do anything for me at the moment, and I don't see how it can do less than nothing.
I think that by winning in the DC District Court, gun owners are better off no matter what happens next. If the Supreme Court does not hear the case, the District where federal gun laws can be challenged is now more gun friendly, not to mention the fact that residents of DC will be able to keep a functional firearm around the house. If they hear the case and render a decision saying the 2nd amendment protects an individual right, I think that's pretty obviously good for gun owners. If they hear the case and ratify the current collectivist interpretation of the 2A, things don't change unless you live in the 5th Circuit or the DC District.
Having the Court take the case and reverse the DC Circuit Court judgement would be the worst possible outcome, and you don't have to take my word for it. I know you like to ask for a cite, so here's the
amicus brief submitted by the states of New York, Hawaii, Illinois, & Maryland. That's what they want to see happen, so that's what I want to see NOT happen.
