This is a second, thoroughly revised and expanded edition of a book that has four clear objectives: to provide a concise account and analysis of international human rights and humanitarian law standards relevant to policing; to set out arguments for compliance with those standards; to show how they may be met in two key areas of policing, interviewing suspects of crime, and policing in times of armed conflict, disturbance and tension; and to make practical recommendations on the management of police agencies. Good practice on interviewing suspects and on policing conflict is included because they are areas of policing where human rights are most at risk. Good management practice is included because intelligent management by enlightened leaders is necessary to secure effective, lawful and humane policing.
