Mass Incarceration on Trial: A Remarkable Court Decision and the Future of Prisons in America. By Jonathan Simon. New York: The New Press, 2014. pp. 224. $26.95 doth.Hidden from sight and forgotten from mind, American prisons in the last forty years have been horrific Petri dishes for medical neglect, interpersonal cruelty, and unspeakable conditions. California, which incarcerates the largest number of inmates (albeit not the largest per-capita), has been particularly notable for its abysmal incarceration practices, so much that, when commenting about his first impression of supermax institutions, Judge Thelton Henderson said to criminologist Keramet Reiter, what was surprising to me was the inhumanity of the thing. Jonathan Simon's new book offers the general public a sobering look into California prisons through the prism of federal court decisions, which encourages humanism and empathy and does not allow the reader to look away.The book tells the story of several federal court decisions that tackled, head-on, the crux between mass incarceration and prison conditions. It begins with Madrid v. Gomez (1995), which exposed the conditions at supermax institutions and critiqued their application to the mentally ill, and proceeds with Coleman v. Wilson (2009) and Plata v. Sclmarzenegger (2009), which addressed, respectively, serious mental and physical health care neglects, culminating in the Supreme Court decision in Brown v. Plata (2011), which affirmed the connection between the mass incarceration project and its outcome-extreme prison overcrowding-and the conditions behind bars. Simon's account of the decisions, and the horrific abuse and dehumanization that brought them about, highlights two main themes. The first is the nature of American incarceration (and California incarceration in particular) as a veritable human rights crime of massive proportions, pulling it out of the American tendency to view things through an internal, exceptionalist lens. The second is the inherent connection between mass incarceration and prison conditions, which are frequently discussed separately in academia and public policy. To Simon, both are manifestations of an overall correctional mentality of total incapacitation: a systemic fear of crime and blanket assumption of dangerousness, coupled with insecurity about the ability to correctly gauge risk, which leads to indiscriminating incarceration of high-risk and low-risk individuals for lengthy periods of time without consideration of the conditions of their incarceration, or of the logistics necessary for their humane confinement. The court decisions reviewed in the book, argues Simon, signal a departure from this ideology, which he defines as a dignity cascade: a willingness to relate to the inmates as human beings who are entitled to more than bare life, but to personal safety, health, and human company.Indeed, Simon's book itself can be seen as an important contributor to a dignity cascade. Written in an engaging, accessible style, and providing the personal stories of plaintiffs in prison condition cases, Simon humanizes the individuals involved and evokes empathy and care for their preventable, horrible plight, while still making the bigger point that the violations are a systematic problem rather than isolated occurrences. …
