Is Oklahoma Frat an Isolated Case?

Sigma Alpha Epsilon was founded in Alabama two months before the Civil War. Now, it's the nation's biggest college fraternity. The President of the University of Oklahoma, former Governor and US Senator David Boren, has expelled two students and banned their fraternity from his campus. It's all about members chanting racist lyrics -- about lynching and that no African Americans will be allowed to join -- in a video that went viral. Matthew Hughey is a professor of Sociology at the University of Connecticut. He studies racism and racial identity.
