Right...I know McDonald "incorporated" the 2nd Amend. But Heller clearly states a ban can't be applied to an entire class of arms commonly in use for defense. McDonald, which was decided post Heller, would help as well.

Personally, from what I've read about Miller, it wasn't a real strongly worded case in many regards. I think the recent rulings are more appropriate to argue, though Miller, under the right circumstances, might apply.
