Another typical day on this board. nikesh looks to be talking sense about forming an alternative action group, starting by taking a cold, hard look at who can realistically be sued - and almost immediately destroys any credibility he might have by asking whether the SFO can be bought.
If TMWNN has genuinely lost a sum well into six figures, and still has some money left, he might be able to do something about it. Everyone else is just screwed. Buchler is a dead end (the idea that he could recover money under PI or D & O insurance, assisted by Pearson, is outstandingly weird; such a recovery would almost certainly need proceedings to be instituted against Pearson in the first instance). The SFO may, just possibly, put someone inside, but that won't help us.
