That's Clayton Cramer's take on the DC Circuit Court of Appeals decision in Parker, which Cramer calls "very nearly the perfect decision, for
the following reasons":

1. Because it struck down key parts of DC's gun control law, DC governnment either has to appeal it to the Supreme Court, or actually deal with DC's violent crime problem by going after criminals, instead
of non-criminals. (Hard decision for them, I'm guessing.)

2. Because the decision recognizes that the right is individual in nature, this isn't a technical win for us, but opens up the door to challenging other federal gun control laws to help determine what are the limits of Congressional and Executive branch authority. For example, if I'm camping in Yellowstone, does the Second Amendment protect my right to have an appropriate grizzly bear discouragement device in mytent? There's a plausible argument based on this decision that I do.

Orin Kerr links the text of the decision (pdf file) while Eugene Volokh has an interesting analysis of the dissenting view of the majority's holding (that the Second Amendment being an individual and not a group right) is mere "dicta."

It will be interesting to see whether the Supreme Court decides to hear the case.
