What specific frauds around MBS and CDOs are you referring to? Certainly some people did indeed see jailtime in the US due to fraudulent use of TARP money for example: https://www.channel4.com/news/factcheck/factcheck-how-many-bankers-were-jailed-for-their-part-in-the-financial-crisis https://www.channel4.com/news/factcheck/factcheck-how-many-b... Also several high-profile executives such as Angelo Mozillo settled for high fines and bars from financial services as a result of SEC enforcement. You can find some of the relevant SEC enforcement actions and their outcomes here https://www.sec.gov/spotlight/enf-actions-fc.shtml https://www.sec.gov/spotlight/enf-actions-fc.shtml although that page appears a little out of date. There were to my knowledge prosecutions also for mortgage fraud etc but just in and of themselves ill-conceived securitizations constitute a fraud.
