The FDIC already charged JPMC the 151 billion for bringing Washington Mutual Inc down. Since the deposits did not suffer any lost this claim will go to Escrow IMO. Don't waste your time looking for files icw this claim to JPMC because all links were destroyed.
Wouldn't it seem more likely that a few law firms would have sniffed out that there are billions of dollars to be had, and would have already been advertising for a lead plaintiff?
