Anja Johansen is Reader in comparative European history at the University of Dundee, UK. She has published extensively on police-public relations, civil liberties activism, and developments of police accountability in France, Germany, and the UK across the 19th and 20th centuries.Genevieve Lennon is Senior Lecturer in law at the School of Business, Law and Entrepreneurship at Swinburne University, Australia. She has published extensively on police law and policy, with a particular interest in accountability and human rights.Hartmut Aden is Professor of European and German public law, public policy and public administration at the Berlin School of Economics and Law (HWR Berlin) in the Department of Police and Security Management and Deputy Director of the Berlin Institute for Safety and Security Research (FÖPS Berlin).Christian Mouhanna (†) was Sociologist and CNRS scholar at the Centre de rescherche sociologique sur le droit et les institutions pénales (CESDIP), France. His extensive, pioneering research and publications cover a range of topics relating to the sociology of policing, security policies, criminal justice, and penal institutions.Marc Alain is Professor at the Department of Psychoeducation at the Université du Québec à Trois-Rivières, Canada, and founder and CEO of the Quebec’s National Police School Research Center (2000–2005). His publications in French and in English cover criminology, in particular juvenile delinquency, and police studies, including contribution to the development of policy and programme evaluations in Quebec, Canada, France, Italy, and Chile.Tobias Singelnstein is Professor of criminology and criminal law at Goethe-University Frankfurt am Main, with a long research track record on German criminal law and criminal procedure. His publications focus on criminology, notably social control and society, policíng and the judiciary, and security studies.

This volume offers a major contribution to the comparative study of police accountability through its integrated qualitative analysis of Independent Police Complaints Bodies across multiple jurisdictions within five democratic countries. It identifies shared structural dilemmas – concerning independence, authority, resources, and legitimacy – that transcend national and institutional differences. By grounding its empirical findings in international human rights standards, the book advances both conceptual precision and normative debate, making it essential reading for scholars and policymakers engaged in the governance of police oversight.Professor Daniela Hunold, Department of Police and Security Management, Berlin School of Economics and LawHolding police to account is both more challenging and more pressing than ever before, and this collection provides invaluable insight and analysis of international efforts to this end. Using original evidence, the authors analyse not only the formal arrangements of accountability but also the power dynamics and cultural and normative frameworks in which they operate. This is an important evidence base that can help to secure democratic oversight of policing.Professor Michael Rowe, Northumbria University, UKThe proliferation of "independent" mechanisms for handling citizen complaints against the police is remarkable. Why and how did this innovation emerge? This essential work provides answers based on research from five countries. It highlights the commonalities underlying the diversity of implementations and how the actors involved have responded. An indispensable resource for policing scholars.Professor Sebastian Roché, CNRS Research Pr., Sciences-Po/University of Grenoble Alpes
