Thousands of people were jailed in 2008 aftermath - look up operation Malicious Mortgage and Stolen Dreams. Most of them of course low level - because those were the people actually perpetrating the fraud. But some examples: Kareem Serageldin, Lee Farkas, Edward Woodard, etc. Ken Lewis, BoA CEO, faced multiple investigations and civil penalties, but none of those investigarions could find any criminal liability. He lost his post and BoA paid out billions in settlements.
