When I was 19 and told the DA I'd be fighting my case and proving my innocence, I watched a vein pop out of his head. He got the better of me though, his dad was the mayor and the judge was in his pocket and they facilitated an absolutely mockery of a trial despite zero evidence, and my public defender was in on the racket and refused to allow me an appeal, and the jail refused to give me new counsel.
This same DA has a reputation for assaulting prostitutes and just got sworn in as the parish judge. I guess playing fair would have hurt his career because my understanding is to be a judge out there you have to demonstrate crookedness.
Louisiana? Not surprised.
