Street criminals live in a dangerous world, but they cannot realistically rely on the criminal justice system to protect them from predation by fellow lawbreakers; they are on their own when it comes to dealing with crimes perpetrated against them and often use retaliation as a mechanism for deterring and responding to victimization. Although retaliation lies at the heart of much of the violence that plagues many inner-city neighborhoods across the United States, it has received scant attention from criminologists. As a result, the structure, process, and forms of retaliation in the real world setting of urban America remain poorly understood. Street Justice: Retaliation in the Criminal World, first published in 2006, explores the face of modern day retaliation from the perspective of currently active criminals who have experienced it first hand, as offenders, victims, or both.
