Policing in Great Britain, Northern Ireland, the Irish Republic, the USA, Israel, South Africa and China

Are police forces agents of the state or of society? How do different police forces maintain order? How does the nature of a country’s political system affect the state’s reaction to disorder? This study identifies trends in public-order policing across a broad sample of seven countries: Britain, Northern Ireland, the Irish Republic, the United States of America, Israel, South Africa and China. It explains why the handling of disorder has become a controversial and topical issue in different parts of the world. Each chapter provides a range of data on the size, make-up and cost of the police and follows a common format in analysing the place of the police at the junction of state-society relations.
