Policing in China is compared to that in the United States, with attention to the nature of community life, police-community relations, police responsibilities, and police organization. Using an interview format involving an American police chief (Knoxville, Tenn.) who participated in an exchange program with a Northampton, England, officer, one article discusses the strengths of British policing. The next article describes the advantages of international officer exchanges, using the Knoxville-Northampton experience as an example. The portrayal of British Columbia's approach to traffic law enforcement deals with a broad-based program of training, public education, community involvement, and research and analysis. The program has resulted in a 10-percent reduction in fatal motor vehicle accidents, a 5-percent reduction in impaired driving charges, and a 10-percent increase in 24-hour roadside suspensions of motorists showing signs of impairment due to alcohol consumption. Current British equipment for the bomb technician is described in another article, including personal armor, helmets, and robots, which permit the bomb technician to distance himself from the device under investigation at crucial times. The description of policing in Hungary considers the varied police duties, police organization, recruit qualifications, training, and crime problems. The discussion of policing in South Africa includes consideration of organizational structure, racial policies in personnel administration, and urban problems. Some articles have photographs.
