No the T/A was not in on anything.
MA sold 50 million shares, you sure about that? Seeing as MA was a company offices he would have to had to disclose that fact.
No RPH can not take all the blame, but he is responcable for a big part of it, with all the lies he put out. Again RPH is not 100% responcable for this scam there are others at fault as well, but RPH was the CEO that signed off an the PRs that contained the lies, as well as the 10-K...Not hard to figure out who was running the scam, just follow the PRs and such and who's name is on them. And again RPH was the face of this scam and he should fall just a bit harder then the other but they all should fall.
