Damn! You should have argued the Miller case!
That stupid U.S. Supreme Court didn't realize that any weapon is a militia weapon. They said they needed evidence! Can you believe that?
That is like asking for evidence water is wet. It only matters to complete and utter buffoons like you.
But the mere fact they didn't take judicial notice that a sawed off shotgun wasn't a militia weapon, which they could have done sua sponte, is significant as well.
