Our police departments are the frontline of defense for society. If society does not feel protected by the police then they are less likely to trust them. Along that same line, some of the citizens will become vigilantes in their own minds trying to “stop criminals”, making the officer’s jobs more difficult than it already is. In the United States, the duty of the law enforcement is to uphold public safety, first and foremost, by reducing the amount of crime in the environment. To achieve this responsibility worldwide, police officers have to partake in many roles. Several of those roles are conflicting roles, depending on the method of the organization, some accentuated over others. All police departments, no matter the location or size, have goals set up. These goals set forth a sense of purpose and direction. The primary goals of policing are the prevention of crime and protection of life, to uphold and enforce the law, to combat public fear of crime, to promote community safety, to control traffic, to encourage respect for the law, to protect the civil rights and liberties of individuals.

Social service is the area where the police help people who need emergency assistance, whether it is giving first aid or finding lost children. Typically, over 50 percent of the telephone calls to the police requesting assistance involve social service as compared with less than 20 percent relating to crime. The police presence in society is also intended to preserve order by serving as a deterrent to misconduct and by providing a quick-response mechanism for potential or low-level problems (Katz, 2011).
