Perhaps that is why the feds bought all those .40 cal rounds. Might be planning a BIG TIME firing squad.
BTW, in traditional firing squads the person being executed very frequently was still alive when the shooting stopped. Which led to the tradition of the officer in charge finishing the guy off with one or more pistol shots to the head.
Which of course brings up the fairly obvious question of why not skip the preliminaries and go straight to the finale, as the Chinese do.
