This part of the Heller decision is something that may cause some problems in the future:
Miller’s holding that the sorts of weapons protected are those “in common use at the time” finds support in the historical tradition of prohibiting the carrying of dangerous and unusual weapons.
I could see the gun control lobby clinging to this line of “dangerous and unusual weapons” and bringing various appeals up to the SCOTUS based upon it.
Which then depends on the makeup of the court five years from now. Obama becomes President we know how it will look and then we could look forward to a 6-3 decision in favor of weakening our second amendment rights.
That is how important this election is. For those thinking of staying at home, or throwing their vote away on a Keyes or a Barr, because of their disagreements with McCain in the past….think about that.
