So it's very possible we could get a ruling that has a pro-RKBA effect in DC but means nothing in California UNTIL we do another case fixing the incorporation issue
Jim's post is accurate as written, but could be misleading, at a quick read, to someone not familiar with con law. It's massively important to keep clear that a pro-RKBA ruling in Heller would
not "mean nothing" outside of DC, even if the Court doesn't open the question of incorporation.
To the contrary, victory in
Heller means that all
federal gun laws -- statutes passed by Congress -- become subject to Second Amendment scrutiny, Second Amendment legal challenges, all throughout the country, in the federal courts in CA or in any other state.
Nonincorporation just means that until 2A is incorporated, Americans can't challenge their own
state's gun control statutes under the federal 2A.
Jim's point is that, since California's noxious gun laws generally duplicate (and go further than) federal laws, California's citizens may not be able to get much ultimate "relief on the ground" (expanded legal gun possession / carry rights) without incorporation, since they need both offending federal statutes
and offending state statutes to be cleared away.
But to people in pro-gun states,
Heller could make a difference very quickly, even without incorporation.
The point is important enough not to obscure, so I offer this explanation even though, as I said, Jim's post isn't incorrect.
