Don't you understand english?
Deliberate misrepresentation or intentional misstatement of the financial products through omission or nondisclosure of relevant financial statement is itself a FRAUD. It's called "fraudulent misrepresentation".
Anyway, you have side-stepped my main bone of contention, which wasn't about Wall Street misdeeds but rather the incompetence and the complicit nature of regulators with the bankers.
I also highly suggest folks to listen to the audio clips from the following link to know WHY none of the Wall Street CEOs went to the jail.
