This study concerns police services delivery in small-to-medium sized metropolitan areas. It addresses three broad issues: the producers of police services, agency cooperation and service delivery, and agency size and service delivery. Each issue is treated in a separate chapter and includes a discussion of several related questions. The 80 geographic areas studied varied in size, population density, and types of communities. The report's findings challenge several assumptions which have been the basis of many proposals for police reorganization. The findings show that policing metropolitan areas can be divided among separately organized agencies as well as among the personnel of a single police department. It is concluded that the diversity in size of agencies and the different combinations of services they produce are not necessarily wasteful or confusing. There appears to be little duplication by small-to-medium sized police agencies. Most police departments seem to know what services they are responsible for and where to deliver them. Instances of duplication, of confusion and of noncooperation are found, but they are not found to be the common pattern. It is suggested that reorganization of metropolitan policing needs to be based on a realistic assessment of the resources and needs of each particular metropolitan area. (Author/AM)
