Book excerpt: The enormous financial cost of criminal justice has motivated increased scrutiny and recognition of the need for constructive change, but what of the ethical costs of current practices and policies? Moreover, if we seriously value the principles of liberal democracy then there is no question that the ethics of criminal justice are everybody’s business, concerns for the entire society. The Routledge Handbook of Criminal Justice Ethics brings together international scholars to explore the most significant ethical issues throughout their many areas of expertise, anchoring their discussions in the empirical realities of the issues faced rather than applying moral theory at a distance. Contributions from philosophers, legal scholars, criminologists and psychologists bring a fresh and interdisciplinary approach to the field. The Handbook is divided into three parts: Part I addresses the core issues concerning criminal sanction, the moral and political aspects of the justification of punishment, and the relationship between law and morality. Part II examines criminalization and criminal liability, and the assumptions and attitudes shaping those aspects of contemporary criminal justice. Part III evaluates current policies and practices of criminal procedure, exploring the roles of police, prosecutors, judges, and juries and suggesting directions for revising how criminal justice is achieved. Throughout, scholars seek pathways for change and suggest new solutions to address the central concerns of criminal justice ethics. This book is an ideal resource for upper-undergraduate and postgraduate students taking courses in criminal justice ethics, criminology, and criminal justice theory, and also for students of philosophy interested in punishment, law and society, and law and ethics.
