If I remember correctly Jason was in protective custody at Riverbend because he had turned on or left the AN gang of the prison and therefor targeted for retribution. He probably gave state's evidence against them the same way as Zach, only earlier. If the prosecution would have only given him some blank maps and crayons he would have testified for weeks, and never implicated himself for anything bad. Anyone who could be so cavalier about gutting a human being has been involved in more than hearing gunshots, IMO. Don't know how they do it but he should spend the rest of his miserable life locked away from the rest of society.
