Remember FDIC-R settled with WMI on pre seizure causes of action and claims. If criminal activity or malfeasance can be shown to have caused Wamu downfall then you got a chance.
FDIC only wants to pay WMB bondholders not corporate. This JPM lawsuit for imdemnification is way out there. JPM is inviting FDIC-R discovery they really don't want. Escrows are better off with court released set-asides monies from disallowance.
