The Examiner's JOB is to find the answers to these very questions. These are very much a part of his examination, as pointed out clearly in his Preliminary Report, and the work load of each of his specific investigation teams. I do not believe that the Examiner will file a Final Report without the answers to your questions.
Class action suit would have to be filed against all parties to find out who was at fault. Was it JPM?; or the FDIC?; or the combination of the two in cahoots with each other?; were there others involved that contributed to this debacle? Why was WAMU only sold off for 1.9 Bil dollars and not for more?
If you don't have a set of these you best put your money in a CD.
