““It is not possible to write a relatively short book that explores all aspects of the phenomenon of mass incarceration and its implications for racial justice. No attempt has been made to do so here. This book paints with a broad brush, and as a result, many important issues have not received the attention they deserve. For example, relatively little is said here about the unique experience of women, Latinos, and immigrants in the criminal justice system, though these groups are particularly vulnerable to the worst abuses and suffer in ways that are important and distinct. This book focuses on the experience of African American men in the new caste system. I hope other scholars and advocates will pick up where the book leaves off and develop the critique more fully or apply the themes sketched here to other groups and other contexts.””
