What Martin is saying isn't making any logical sense. If he produces the documents he can declare his innocence in this trial. If he doesn't produce these documents, he defaults on this trial, and he still might have to produce them at a later time anyways.
The only possibility of this happening is he was being used as a shell/cover for the whole fraud & someone is paying him off for more than FB sued him not to rat & he is their puppet bitch. Being the only way he would rat on them if his ass faced Federal prision time.
