I believe that Ray Haffner is Red John, which would explain why Bret Stiles had the info he did on RJ. The main reason for my thinking this is that it was revealed in the "Red Barn" episode that Ray is a member of Bret Stile's Visualize cult. Early on I thought that Bret Stiles was RJ. It's obvious that Bob Kirkland is a disciple of RJ and I believe that other suspects may be followers of RJ also.
