Eric Holder, the attorney general at the time, did not prosecute bankers for the 2008 recession. The attorney general did prosecute people responsible for the issues in the dot com crash.
How is that comparable? Holder even stated, "I am concerned that the size of some of these institutions becomes so large that it does become difficult to prosecute them" because it might damage the economy. That is not an aspect the AG should be considering. They should be upholding the rule of law which did not occur after the 2008 crisis
