You may not like MSNBC or Eliot Spitzer but he and Dylan Rattigan obviously know very well what they are talking about here and it's as good a summary as any about the explosive 2,200 page report about Lehmans collapse
http://www.msnbc.msn.com/id/21134540/vp/35841681#35841681Rattigan goes into detail about how "repo transactions" work , and towards the end Spitzer darkly implies the Fed knew all about it and calls for transparency from them. lotsa luck with that
