THAT is the overriding question. A forensic accountant can determine (a) precisely how much money was taken in from investors and (b) how, when and where it was spent. The IRS will determine if expenditures were legitimate and the tax implications of every dollar that changed hands.
IMO, Eddie Vakser has personally run this entire circus from the start. The financials that were filed were created by him with little, if any, oversight.
