“Normally you would be correct, here you are not: you see in a military case there are stronger compulsory process/powers for the accused [that is, investigation] precisely because of the constraints imposed upon them by orders (and the consequences of acting on them when illegitimate). “
Nope. sorry, but I spent 25 years in the USAF, and there is not some special powers of discovery given over to accused military members.
You cannot accuse your neighbor of embezzlement, and then use discovery to see his bank records. You first need some EVIDENCE. Otherwise, you will never get to the discovery phase.
Of course there is [evidence], it's in the way things have been shuffled. (Butterdzillion has some good investigative material, evidence of microfiche tampering IIRC.) If you are given an order, which might not be legitimate you have the opportunity to challenge its validity, the LTC did this (he was basically told "shut it" by his superiors) -- this in itself is indicative of malfeasance possibly covering up ineligibility. -- Moreover, the "birth certificate" released on the white-house's website was a forgery, that too is indicative of ineligibility.
The interesting thing is how much [almost] EVERY challenge has been shot down, not due to lack of evidence, but "lack of standing" which means that it didn't matter how much evidence they had.
