The whole language argument boiled down into a nice, tasty (heh) serving:
The post has a great summary of how Heller vs. DC entirely blew away the whole "the Second Amendment only applies to the militia" argument. And since this avenue of attack has been closed down, the anti gun crowd has shifted to "let's explore just how far we can restrict this individual right" (i.e. what's happening in Virginia).
It's been a long time since Heller (or MacDonald), and there are new Justices on the SCOTUS. I'm quite frankly suspicious of Roberts who seems entirely squishy, and so we'll need an "insurance" Justice*. Maybe two. The implication is that it will be 2-3 years before the court can seriously assess strict construction (assuming they want to).
