A powerful critique of mass incarceration by the people who have experienced it Inside Knowledge is the first book to examine the American prison system through the eyes of those who are trapped within it. Drawing from the writings collected in the American Prison Writing Archive, Doran Larson deftly illustrates how mass incarceration does less to contain any harm perpetrated by convicted people than to spread and perpetuate harm among their families and communities. Inside Knowledge makes a powerful argument that America's prisons not only degrade and debilitate their wards but also defeat the prison's cardinal missions of rehabilitation, containment, deterrence, and even meaningful retribution. If prisons are places where convicted people are sent to learn a lesson, then imprisoned people are the ones who know just what American prisons actually teach. At once profound and devastating, Inside Knowledge is an invaluable resource for those interested in addressing mass incarceration in America.
