Drawing on data from Germany, the book focuses on changing narratives of youth crime in recent decades and the exact narratives that have been used, abandoned, invented or criticized in order to instil particular understandings of crime and measures to act against it. The author draws upon a wide range of sources, including debates on youth crime in six parliaments from 1970 to 2012; articles on youth crime in four police and six social work journals from 1970 to 2009; and case studies with 15 young defendants who were interviewed before and after their trial and whose trial was observed. In doing so, the author reconstructs narratives over several decades and, overall, reveals a fascinating and multifaceted scope of narratives of youth crime. This book will be of great interest to students and scholars of youth crime and justice, as well as criminology, sociology, politics and social work more broadly.
