Thats why the JPM should be wary of the government. The FDIC has the gun and bullets, locked and loaded. If the FDIC comes out tomorrow and states that it made a critical error during the heat of the financial crisis and would seek to recover or undo the deal. Then JPM would either have to pay or give back WMB.
The media and the DOJ would not go after the FDIC because Obama would tell Treasury to squeeze some balls and crack some heads on wall street.
Don't mess with the government. The government can be ruthless because if JPM goes after the FDIC, the administration can release the hounds at the DOJ after JPM and you can bet they have some skeletons.
GLTY. IMO, JPM would be well informed to start buying up shares through some hedgefund or foreign subsidiary to cut their losses.
