The inmates at San Quentin are often highly intelligent–and usually sociopathic. Due to its racial and gang related violence, the residents refer to California’s oldest prison as “The Arena.” But aided by 4,000 volunteers, many prisoners try to improve themselves by taking undergraduate college courses, produce their own newspaper, organizing theatre productions, and engage in other endeavors. One inmate, Curtis Carroll, has been diligently studying financial analysis, and has built a reputation in the big house for teaching his fellow inmates how to become stock pickers as “The Oracle.” Breitbart | by Chriss W.
