And besides, you can't force the SCOTUS to do anything.
Even with the clear conflict between the Ninth and Fifth Circuits on the basic meaning of the Second Amendment, they refused to hear the appeal of Nordyke v. King.
Did Nordyke v. King make Second Amendment claims? I thought that I read that it was a First Amendment claim that assembling at a gun show was a form of political or cultural expression. Maybe I have it mixed up with some other case.
