As to whether this means anything good, I would have to say: No. My reason for saying that is that the latest liberal twist of common sense is to say, "I believe in the second amendment but there ought to be laws preventing people from having guns." If this makes sense to you then you might be a liberal.
Actually, the whole idea is that, when cornered by logic they can wail, "But I said I support the second amendment." The rest of the time they're all for "reasonable" laws for "reasonable people." Thus they can have their cake and eat it too.
There is a glimmer of hope for Californians, though. Part of the decision in Heller
will be whether or not to incorporate
the second amendment, making it apply to the 50 states. I'm almost afraid to hope for this but hope I do.
