Well, it will be easier for the liars and simpletons and partisans to explain this in their dishonest way, than for sophisticated persons to figure it out and explain it. it helps that Barney Frank wants to find out more details, also. Issa is a very partisan republican, and if it were just his project it would be totally suspect. The point in finding out what happened should be to provide a basis for new regulations, to prevent something terrible from happening again, which it could if there is not adequate regulation, and provision for break up of the too big to fail financial and corporate institutions. i do not think that is Issa's motive. He is mostly a right-wing partisan GOP hatchet-man type.
