The insanity of the charges/sentencing reminds me of a passage from The Hot House (which is excellent, Pete Earley somehow got permission to go mingle with prisoners at USP Leavenworth for a year and write about it). A Bank Robber, 45 'They originally charged me with murder, kidnapping, and bank robbery, but I'm really just a bank robber with really bad luck. You see, my buddy and me were robbing this bank, and when…
What if his friend wasn't dead, but in fact died in the car as he was driving away from the scene? What if his friend's life could've been saved by treatment at the scene? Moreover, did he have a plan for saving his friends life or was he simply trying to get them both away from the police? Furthermore, being charged with something is not the same as being found guilty of it. The quote begins, "They originally charged me," so I'm guessing some of the charges were dropped? Even then, it comes down to a jury to decide guilt.
I binge-watched a bunch of prison documentaries recently (in particular, Into the Abyss and the series by Louis Theroux are very good). They shed a lot of light on the terrible aspects of the U.S. prison system. Interviews with inmates, though, also make it clear that a lot of these people:
a) Know next to nothing about the legal system outside of their own interpretation of whatever their lawyer/judge has told them. Think of explaining programming to someone who doesn't regularly use technology, and then they go and explain it to someone else.
b) Maintain their innocence even in the face of extremely damning physical and forensic evidence to the contrary. Into the Abyss has a great example of this.
I have fundamental problems with the adversarial justice system, but it's nonetheless important to be critical of what convicts say about their own situations. They're obviously going to be biased - even if they are innocent.
