Book excerpt: Mass Incarceration on Trial examines a series of landmark decisions about prison conditions-culminating in Brown v. Plata, decided in May 2011 by the U.S. Supreme Court-that has opened an unexpected escape route from this trap of "tough on crime" politics. This set of rulings points toward values that could restore legitimate order to American prisons and, ultimately, lead to the demise of mass incarceration. This book offers a provocative and brilliant reading to the end of mass incarceration.
