Anyone interested in American criminal justice has to wonder why we have so many more people in prison—in absolute as well as relative terms—than the western half of the European continent, the part of the world most readily comparable to us. This book, consisting of eleven chapters by eminent criminal law scholars, criminologists and political scientists, provides both a detailed look at how U.S. punishment is different and an insightful analysis of why that might be so. While many chapters in the book describe previously declared positions of the authors, there is also much that is new in the book, particularly with respect to non-prison sanctions; whether veterans of the field or newcomers to it, readers should find this collection of the area’s leading scholars extremely useful.
