What did the professional model of policing emphasize?

The professional model of policing primarily emphasizes a structured and organized approach to law enforcement, which includes aspects of crime fighting, prevention patrol, and reactive policing.

Crime fighting is a fundamental aspect of the professional model, as it focuses on the enforcement of laws and the reduction of crime through proactive measures. This approach highlighted the importance of police work in maintaining public safety and order.

Additionally, prevention patrol is a key component of this model. It involves proactive strategies designed to deter crime before it occurs, such as increased visibility of officers in the community. The goal is to create an environment where potential offenders are discouraged from committing crimes due to the presence of law enforcement.

Reactive policing also plays a role within this framework, as it deals with responding to incidents after they occur. While the professional model prioritizes proactive measures, it recognizes that responding to calls for service and investigating crimes is essential to effective policing.

By encompassing all these elements—crime fighting, prevention patrol, and reactive policing—the professional model of policing aims to create a comprehensive strategy for maintaining public safety and responsiveness to community needs. This holistic view is what makes the answer "D. All of the above" correct.
