Is this the one where Meathead (Meatus Head, a term for [D*ck head])brings up the old 1939 SCOTUS decision that there was no right to keep and own firearms? That is the only All in the Family show I ever watched.
For those interested the 1939 decision had to do with a sawed off shotgun being brought from Tulsa OK to Siloam Springs Arkansas to rob a store. The plaintiff did not show up to plead his case as he was dead, so the SCOTUS went with what the Government lawyers said.
Actually the Miller court said that military firearms were protected by the 2A but they weren't shown any evidence that a short barreled shotgun was a military arm that would be protected. Of course they were but as you mentioned no one was present to represent Miller as he was dead.
That decision has been misread and twisted by gun grabbing judges and lawyers ever since.
