Sorry Jane but this is a gross misrepresentation of Mike's work on the case. And bad advice to boot. Mike's research, questions and theories should be viewed individually; and not simply tarred with some great brush of judgemental disdain. Mike was extremely intelligent in my opinion; and he had experience first hand of corruptive police practices. The breadth and depth of his research on the case deserves respect, even if some of his claims did go well awry. I also think it fair to say that he was not a well man, for a long time and he deteriorated considerably.
Sometimes Mike was plain wrong but other times, Mike was sending a message.. if it's OK for the police to 'bend' the evidence.. then here is some of their own medicine.
It seems that both JB and MT's trial judge would agree with your assessment of MT's IQ! He loved to tell us that JB called him a "clever B*****d", and the trial judge said similar -using rather different terminology, of course!- but neither could be said to be overtly complimentary, more back-handed.
I believe, unquestionably, that MT was a good friend to JB -with the reservation that he probably had his eye on a share of the proceeds from potential book/film which would, naturally follow on from JB's release, on the back of which he allowed his imagination to run wild- but we are, after all, speaking of someone who had lived his life, with no great success!, on the wrong side of the law. I have no idea why it was that JB 'dumped' him, but it might be worth considering that one of his "wackier" ideas could, ultimately, have led to a truth being revealed, JB would sooner not have been? Whatever, I don't doubt that MT would have been very hurt by the cut off............but it didn't stop his earlier devotion from getting the better of him, and he'd had enough experience of courtroom/legal 'speak' to word his claims in a way which was entirely believable.
Conscious of the enormous affection in which MT is held by many here, who also believe his claims to be true, I won't list those I believe to be untrue, but I have ask how it was that the huge number of those whose job it was to uphold the law, saw fit to 'offload' to someone who'd spent his entire life -mostly unsuccessfully!- breaking it, only to have attempts made on his life by the Secret Service, because of what he, allegedly, knew?
