Security and Risk Technologies in Criminal Justice takes students through the evolution of risk technology devices, processes, and prevention. This seminal text unpacks technology’s influence on our understanding of governance and social order in areas of criminal justice, policing, and security. With a foreword by leading criminologist, Kevin Haggerty, the collection consists of three sections that explore the impact of big data, traditional risk practices, and the increased reliance on technology in criminal justice. Eight chapters offer diverse examples that are linked by themes of preventative justice, calculability of risk, the theatre and reality of technology, and the costs of justice. With both national and international appeal, this vital resource is ideal for undergraduate and graduate students in criminology, police studies, or sociology.
