If all the ringmasters want to accomplish is to "set the record straight" all they need to do is release their information to the public. They do not need to have the BoT put its imprimatur on it. Similarly, if their evidence exculpates the Grinning Baboon, they should give it to his attorney. The BoT cannot reverse his conviction.
But they'll do none of those because then their circus ends and they recede into total irrelevance.
