Book excerpt: This book is a study of urban police and their interest in obtaining power as individuals within the organization and collectively within the community. Urban society, beset by increases in crime and violence and the growing irrelevancy of primary socializing agents, must look to the police, the institutionalized control agency, for the preservation of peace, order, and tranquility in the community. The dilemma of a democratic society is how to give the police sufficient power to perform their role effectively, while at the same time maintaining restraints on the police in order to prevent abuses to democratic principles. This book looks at the discretionary conduct of policemen and whether adequate accountability measures exist -- and, if not, whether they can be realized, while allowing for the necessary development of police capabilities in the performance of requisite functions. In its focus on the behavior of police officials and the relationship of the police bureaucracy to the urban political system, the work strives to be both descriptive and prescriptive. The author uses examples from a cross-section of American cities and focuses on Memphis, Tennessee to illustrate the political events and social factors which effect policing. Collective police power is measured by the extent of their discretionary authority and freedom from external controls, individual power is perceived by the rational strategies on the part of police officials striving to attain or consolidate their personal power positions in the organization. Implicit in the police's struggle for power -- both personal and collective -- is the existence of conflict with challenging institutional and environmental forces and actors.
