"Patterns of Policing" is the first comparison of the development and operation of police in countries throughout the world, concentrating on Asia, Europe, and North America. Bayley examines the variability in police work, suggests reasons for this variation, and makes preditions about the future role of police.

He considers how contemporary police institutions have developed. Police forces worldwide tend to be public rather than private, to concentrate on crime fighting rather than services, and to be professionally trained and recruited. There is, however, great variation in the structure of police forces, which are generally either centralized or, as in the United States, decentralized.

The behavior of the police toward their constituents also varies by nation. As urbanization and industrialization increase, the public finds itself in greater contact with police and may begin to rely on them more for protection. There are also marked differences cross-nationally in the way police relate to political and community life.

"An eye-opening and somewhat heroic construction designed to shift our perspective on the nature and causes of police work... important and long overdue... By design, it is an empirical and wide-ranging work that pays attention to the available numbers and public claims of police officials. " - Contemporary Sociology

"Bayley has posed key questions on police functioning... and responded by using a model-building approach based on theoretical propositions and subjected to an international data base. " - Choice
