Like: First the punishment, then the trial?
Several years ago I met Pastor Roby Roberson, accused of turning his Wenatchee, WA church into a child-molestation ring. Tossed into jail, the guards did nothing when he was beat up.
Of course, he was subsequently acquitted, and by now I think every contested related conviction has been overturned. (I'm not sure about uncontested convictions.)
I just checked and amazingly, the story is still online at the Seattle P-I site here.
It's cases like his that point out the reason for administering punishment after a conviction obtained via due process.
All traffic laws were obeyed, and with red lights flashing, siren screaming we proceeded to the hospital at 10 mph. Unfortunately the child killer was pronounced dead on arrival. I won't say where it happened, but a lot of court time was saved.
