If I'm not mistaken, the AIG bailout and Tarp are different things. AIG was a direct and accountable bailout. Tarp is a giant slush fund with loosely defined rules and accountability.
AIG can be accounted for by money in and money out.
Tarp money moves in, out, around and through. Deceptive claims of loss or gain are made on snapshots of money movement rather than beginning to end accounting.
