I need to do a research paper on JPM and their involvement in the meltdown of the current financial crisis, such as sub-prime lending, defaults, JPM's investment decisions, their best & worst decisions, how it all effected them in good/bad ways, etc., within the last 3 years, '06 to '09. I have looked for articles online but there is just an overwhelming amount of information.

Also i was hoping to find some info about how Jamie Dimon became the CEO of JPM; didn't he used to work for Citi and when he wasn't promoted to CEO he left as a means to sort of get his own revenge, or something along those lines?

Your help would be greatly appreciated. Please paste the link to any helpful articles. Thank you!!
