Im not so sure. It may reveal what we suspect, on a grander level, but, really, what could be done? I may be wrong on this, and would love it cited, but I dont believe congress has legislative authority over the fed. Sure, the fed sits in congressional commitee meetings, but if you watch The Fall of The Republic, you will see footage of those meetings...you will see senators asking Bernanke how much was given to what banks, and when. Bernanke basically said I dont know, and if I did, I dont have to tell you.
Anyway.
