Sadly true. I think Heller had to sink-in, even amongst those Judges who agreed to understand just how profoundly jurisprudence had been perverted up to this point with the idea of a "militia right". This legal fiction had polluted virtually every decision made since 1934 in one way or another...In the end, that probably wasn't such a bad thing.
I don't think this case would have been successful without all the cases that have come out in the past five years, particularly one right on point written by Richard Posner.
Much as I pointed out in another thread that we as gun owners fall into the programming traps and need to constantly step back and ask "why do we accept this, or that?", judges too have been coming around slowly and asking "wait a minute? If X, then naturaly Y follows..." and opening many cans of worms (in a good way).
