Sorry to say, but not an easy task. SEC and FINRA has copies of all trading activity on this or any other security, but very tight-fisted with the records.
My advice would be to read through the court transcripts and draw your own conclusion. Again, this is only a little project I am working on, so don't know all the details, but somewhere in those transcripts I believe judge allowed a company representative and, in turn, gave permission to rep to obtain necessary doc's to put entire trading puzzle together.
Others I have done research on confirm what is being stated here. Only in case of Taser and a few others has NSS been exposed. Lawsuits are timely and costly against people hiding behind a curtain. Much easier for SEC to go after company, as principles are known. For either ease for SEC or an assortment of other reasons, SEC normally begins and ends at company level.
Not sure about conspiracy theories, but SEC seems to be looking in both directions now, and revocation is taking much longer than normal, as others have alluded to here.
Long answer to short question, but suggestion is to follow BK case. Most all answers can be found there. Will you ever see any of your investment? Chances are not in your favor, but judge is federal and not taking crap from anyone, including (if not especially) Trustee. He seems to want everything sorted out before making a ruling. Will that include NSS? The trading patterns indicate a high likelihood.
