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.
