This text provides an accessible, up to date and comprehensive introduction to police ethics and values for all those undertaking degrees and foundation degrees in policing and related subjects. The recent introduction of directives, legislation and Codes of Standards has demanded a more principled and professional approach to policing. This book therefore provides a clear understanding of police ethics and values and how these are understood in policy and applied in an operational setting. It discusses the range, importance and complexity of ethical issues faced by law enforcement practitioners and policy makers, introduces the key concepts of ethics, professionalism and policing, and relates these to key themes within policing.
