Paul Butler was on track for the American dream. A graduate of Yale University and Harvard Law School, he was a federal prosecutor for the U.S. Department of Justice specializing in public corruption. All that changed when he was arrested on charges he claims are false. That’s when he decided the system simply didn’t work. He is now a law professor at George Washington University and author of Let’s Get Free: A Hip Hop Theory of Justice and advocates that the public force major changes in the criminal justice system.
