The only part of the usual BDI theory that these interviews are making me question is that John and Patsy covered up the murder for Burke. Patsy might have, but I cannot believe that of John after seeing this. He had to have known that Burke would not come out well in these interviews. He could have given an interview with Dr. Phil himself. That would have been protecting his son. Even with renewed attention on the case, there is no reason for Burke to come on television so that the entire world knows what he looks like. Burke isn't a public figure and has been hidden away before. He doesn't even have to leave his home to work. If John knew about the cover up before it was too late to stop it, his reasons had nothing to do with his love for Burke.
