It may not impact it at all. The supreme court will most likely incorporate the 2nd Amendment to the states, but allow for "reasonable" restrictions and regulations. Unless they rule that individuals have a right to carry, we will still be in the same situation.
It's not going to directly or immediately do so. It will open the door for challenges to what will then be unconstitutional law. California has no RKBA in it's state constitution. And since the US 2A is not incorporated, we do not have that right. Once we do, we can legally challenge laws like 12031.
Yes and no. RKBA litigation is on the fast track with follow up cases filled or in the wings. The dicta in McDonald will help to point the way too. McDonald also allows us to tie up new legislation with injunctions pending a courts deciding it's constitutionality (a la prop 187 from years past). Which is why I don't want UOCers inspiring any new in the next 6 months and am asking for a stand down for now.
