When we first conceived of this book we set out to explore the changing landscape of ethics regulation in the UK as it has impacted on criminology, and we wanted to alert readers to an ever-widening range of challenges. But we also wanted to outline some possible solutions, or at least to give examples of ways in which the challenges have been addressed. The subject of ethics in criminology and criminal justice has certainly gained prominence over the past two decades or so, as concerns about risk in higher education institutions, criminal justice agencies, other public authorities and individuals have prompted ethical questions and recognised the need to establish standards and provide guidance to those with whom they engage.
