Last night, 60 Minutes ran an excellent piece called “Inside Edge” about former stock analyst Roomy Khan. Khan was caught early by federal prosecutors investigating insider trading by hedge funds, and ultimately became a critical government informant in the criminal case that brought down Galleon Group’s Raj Rajaratnam and dozens of others.

In Inside Edge, 60 Minute’s Bill Whitaker interviewed Khan about how she came to the U.S. as a student from Delhi, India. She rose to become worth $50 million before the insider trading scandal that ultimately led her to downfall. Khan is now unemployed and living in Florida following her recent release from prison.
