Off topic, but this is just such an incredible and indepth glimpse into the investigation that I could not resist. This link
(PDF file) is to a DOJ presentation summarizing their case. This is a
tale of institutionalized fraud, orders to destroy records, a
whistleblower (who collects 30% of damages), and secretly recorded conversations,
ending with the realization, “we're all going to jail.”
