of conduct and uniform training standards became the foundations of American law enforcement with the professional and efficient delivery of police service its ultimate goal. The present model requires that officers not associate too closely with the people they serve, an obvious reaction to the corruption evident in the earlier models. Modern devices have added the professional model of today. At about the same time, much-needed equipment and technology (cars, radios, telephones, and mobile-digital terminals) began to arrive on the law enforcement scene(Zhao, 2).
