According to Jeffrey Patterson, who wrote Learning the Lessons of History, this idea also gave rise to the International Association of Chiefs of Police (IACP) which called for the centralization of authority in strong executive positions, and the adoption of a civil service personnel system. .
The idea of removing politics from policing was shared by both the urban elites and police administrators, which gave rise to the idea that a police profession could be formed to resolve problems such as corruption. Policing was not the only part of living in a city that city dwellers wanted to change, it was just one component to help clean up the city, and rid cities from corruption. "The progressive movement began to promote professionalism in law enforcement as one of the basic components of rehabilitating municipal politics" (Patterson). "The concept of a profession includes the expectation that its practice requires special training, skills, or abilities, that its members are committed to the vocation, and that they are entitled to some degree of autonomy in their activities" (text, 90). This idea of professional policing can be summed up in the IACP's mission statement: the association's goals are to advance the science and art of police services; to develop and disseminate improved administrative, technical and operational practices and promote their use in police work; to foster police cooperation and the exchange of information and experience among police administrators throughout the world; to bring about recruitment and training in the police profession of qualified persons; and to encourage adherence of all police officers to high professional standards of performance and conduct. .
The driving force behind the professional model becoming possible was the advancement in technology. Mainly the automobile, telephone, and radio were to account for this, because they allowed officers to respond to service calls and got them in the streets patrolling, but also to some extent ballistics, chemistry, and fingerprinting helped advance the professional model.
