There is a process of self-enlightenment that operates among inmates, a process that moves far beyond the level desired by the authorities. A “rehabilitated” prisoner may see the “incorrect” nature of his past actions. He may even see that the assault or robbery, or whatever, was a “mistake.” But he comes to see that “mistake” in a particular light. Many prisoners reach this point and fly past it to a deeper and broader assessment. They begin to assess society and see that their “crimes” were in part a result of a capitalist and exploitative society. Frequently, they become socialists, recognizing that capitalism has given birth to the murderous twins: imperialism and racism. These enlightened and politically conscious prisoners arrive at convictions that the authorities find unacceptable and threatening. Even though inmates at this point may have no intention of ever committing crimes again, they are held in prison for a longer time because of their new opinions rather than because of their prior activities. When they appear before parole boards, they are questioned not about the past but about their views of contemporary social issues. If they are honest and tell the truth, they are denied parole. They were sent to prison for what they did, but they are kept in prison for what they believe. These are political prisoners. George Jackson and Booker T. Lewis are two well-known examples, among thousands less visible.
