m.makana.h, You are correct that some courts have rejected the idea that the right to bear arms applies only to those in a well regulated militia.  However, in my opinion, they were legislating from the bench, as their rationale is tortured and renders the first half of the Second Amendment irrelevant.  NRA has arguments, but they aren't strong.  As you observe, there's lots of data that disproves NRA's contention that guns save lives in home invasions.
