There's two issues here...is he innocent, or should he have been found innocent?
I agree with most...from what we know of trials, it's rather hard to believe he was convicted, or that he should have been convicted. Probably goes to show you that the trials we are mostly familiar with are the ones that the legal teams are under public scrutiny, and the defendants have access to high quality defenses. It probably conditions us to think that questionable convictions happen a lot less often than they actually do.
However...I think he is guilty. I want to listen to undisclosed...but someone give me a spoiler...how do they explain Jay knowing where the car was?
That's all I need to know, because until that is even plausibly explained (Serial made almost no effort to do so, just brushed it aside), that means:
A) Adnan killed her and Jay helped after the fact, basically the same as the official record
B) Adnan and Jay killed her together, meaning Adnan should be in jail, and Jay should be as well.
C) Jay killed her, and Adnan was an accessory after the fact, basically in reverse of the official story, making Adnan a liar if not a murderer.
If it's C, why did Adnan not roll over on Jay, and CONTINUE to not roll over on Jay to this day?
Just tell me how Jay knew where her car was if Adnan is truthful and innocent. I just want that explained.
