I seem to remember that case way back when. I think if I'm not mistaken, Sandra Day O'Connor, who was known for her anti gun positions, actually voted in favor of Thompson Center saying the possession of a Thompson rifle barrel and a pistol by the same owner made him no more guilty of "owning" a short barreled rifle, than a person who possessed a shotgun and a hacksaw would be guilty of "owning" a sawed off shotgun. Not a bad argument if you think about it. Bill T.
