This book examines the impact and implications of the relationship between risk and criminal justice in advanced liberal democracies, in the context of the revolt against uncertainty which has underpinned the rise of populist politics across these societies in recent years. It asks what impact the demands for more certainty and security, and the insistence that national identity be reasserted, will have on criminal law and penal policy. Drawing upon contributions made at a symposium held at Victoria University of Wellington, New Zealand in November 2018, this edited collection also discusses the way in which risk has come to inform sentencing practices, broader criminal justice processes and the critical issues associated with this. It also examines the growth and making of new risky populations and the harnessing of risk-prevention logics, techniques and mechanisms which have inflated the influence of risk on criminal justice.
