Well, I believe that there will obviously be an effort to scapegoat some low level suckers, and, as such, the whole effort is garbage.
The basic principle is liar's reports are worthless. When reporters want to create a particular outcome (no executives should do hard time), what you end up with is fundamentally dishonest. And since we have reasonable doubts about the integrity of the investigation -- it's being performed by employees of the original deceivers -- the whole thing is garbage. You can't take it and unshade it a little bit; people who have proved their untrustworthiness simply cannot be trusted. Not just a little bit; not at all.
ps -- what constitutes a believable report? One done by criminal investigative services belonging to a country where the government doesn't own a major stake in the company being investigated.
