That is "presumed innocent until proven guilty". It's legalese and has nothing to do with anyone's opinion except those on the jury. OJ is guilty even though not convicted. Soldiers who were stationed with him have come forward and said he told them he was leaving. E-mails to his father indicated his disillusion. His actions of sending his personal effects home indicate something. Leaving a note indicating he was heading out say he was a deserter. Asking villagers directions to the Taliban is a red flag. I do not presume him to be innocent even if he says he is.
Doesnt effect anyones opinion true, but the Jury are the ones who will decide whether he goes to jail or not.
