How does this change with the latest ruling in California? Or does it not change?
I'd it doesn't change other than to get SCOUTS closer to addressing the right-to-carry issue. All of the circuits, including where we've lost, have agreed that the Second Amendment is to some degree applicable outside the home.
Where the circuits split is in the regulation of that right. The Second, Third and Fourth circuits have been highly deferential to the states in minimizing the extent to which those regulations burden the exercise of the right. Those courts have basically agreed with New York, New Jersey, and Maryland that the challenge regulations in those state are necessary and don't overly burden the right. The Ninth Circuit, on the other hand, has come to the conclusion that San Diego's policy doesn't burden the right, it removes it.
We're getting closer to the tipping point where the accumulated case law is large enough and diverse enough that will be necessary for the Supreme Court to step in and provide some rules for the lower courts to follow.
