Providing an accessible and comprehensive introduction to ethical policing, this book contributes to policing as a field of study by emphasizing the important contribution philosophical inquiry makes to the evidence base. It does so through a critical examination of the literature on police ethics. It also highlights the limitations of descriptive ethics found, for example, within the procedural justice literature, and seeks to enrich our understanding of police legitimacy by providing a moral philosophical perspective to the debate. It provides a conceptual and theoretical basis to understand the fundamental role of police and relations with society in respect of philosophy.
