This story says that the government has decided to prosecute one Lee Bentley Farkas for financial fraud. As a non-lawyer, and seeing only the description in this and related stories, it is very difficult for me to discern the difference between what Farkas did and what Citigroup did. I have a generic concern that there are enough laws to make many activities illegal, particularly in finance. As a result, there is much discretion for prosecutors to focus on the politically vulnerable and exempt the politically connected.
