Connections. I don't believe that money alone would have bought their freedom. You have to know who to bribe, and with how much, for it to work. Without the connections, all money can buy is high priced attorneys. I don't really believe that JR bribed anyone. I do believe there were connections with too many influentual people that may have had their own skeletons to hide. IMO, they were probably connected in ways most people would never imagine, or want to believe.
