Jon Corsine was deeply involved in MF Global trading

His obsession with trading was apparent to MF Global insiders over his 19-month tenure. Mr. Corzine compulsively traded for the firm on his BlackBerry during meetings.

This makes his Sgt. Schultz “I know nothing” stance untenable. And really, the CEO shouldn’t be trading during meetings, if at all. Maybe he needs Gamblers Anonymous?
