. Although there exists an inherent interrelatedness between the different groups that make up the criminal justice system based on their crime deterrence purpose, each component operates independently from one another. However, the judiciary is vested with the power to make legal determinations regarding the conduct of the other two components. Apart from maintaining order and service functions, the purpose of policing is the investigation of suspected criminal activity and the referral of the results of investigations and of suspected criminals to the courts. Law enforcement, to varying degrees at different levels of government and in different agencies, is also commonly charged with the responsibilities of deterring criminal activity and of preventing the successful commission of crimes in progress; the service and enforcement of warrants

Types of police

Policing in the United States is conducted by numerous types of agency at many different levels. Every state has their own nomenclature for agencies, and their powers, responsibilities and funding varies from state to state.

 responded to the Hurricane Katrina natural disaster. Command in such situations remains a complex and flexible issue.

The federal government is prohibited from exercising general police powers due to restrictions in the constitution, due to the fact that the United States is organized as a union of sovereign states, which each retain their police, military and domestic law-making powers. For example, the State's National Guard is the state's military. The constitution gives the federal government the power to deal with foreign affairs and interstate affairs (affairs between the states). For policing, this means that if a domestic crime such as murder is committed in a state and the fugitive does not flee the state, the federal government has no jurisdiction. However, once the fugitive crosses a state line he violates the federal law of interstate flight and is subject to federal jurisdiction, at which time federal law enforcement agencies may become involved.

Police functions

Florida Highway Patrol in Action
Textbooks and scholars have identified three primary police agency functions. The following is cited from The American System of Criminal Justice, by George F. Cole and Christopher E. Smith, 2004, 10th edition, Wadsworth/Thomson Learning:

  • Order maintenance. This is the broad mandate to keep the peace or otherwise prevent behaviors which might disturb others. This can deal with things ranging from a barking dog to a fist-fight. By way of description, Cole and Smith note that police are usually called-on to "handle" these situations with discretion, rather than deal with them as strict violations of law, though of course their authority to deal with these situations are based in violations of law.


  • Law enforcement. Those powers are typically used only in cases where the law has been violated and a suspect must be identified and apprehended. Most obvious instances include robbery
    Robbery

    Robbery is the crime of seizing property through violence or intimidation. At common law, robbery is defined as taking the property of another, with the intent to permanently deprive the person of that property, by means of force or fear....

    ). Cole and Smith cited one study which showed 80% of all calls for police assistance did not involve crimes, but this may not be the case in all parts of the country. Because police agencies are traditionally available year-round, 24 hours a day, citizens call upon police departments not only in times of trouble, but also when just inconvenienced. As a result, police services may include roadside auto assistance, providing referrals to other agencies, finding lost pets or property, or checking locks on vacationers' homes.


Styles of Policing

Given the broad mandates of police work, and yet having limited resources, police administrators must develop policies to prioritize and focus their activities. Some of the more controversial policies restrict, or even forbid, high-speed vehicular pursuits.

Three styles of policing develop from a jurisdiction’s socioeconomic characteristics, government organization, and choice of police administrators. According to a study by James Q. Wilson (”Varieties of Police Behavior”, 1968, 1978, Harvard University Press), there were three distinct types of policing developed in his study of eight communities. Each style emphasized different police functions, and were linked to specific characteristics of the community the department served. (Wilson’s field of study was in the United States, and it is not clear if similar studies have been done for other countries with different governmental organization and laws.)

  • Watchman. Emphasizes maintaining order, usually found in communities with a declining industrial base, and a blue-collar, mixed ethnic/racial population. This form of policing is implicitly less pro-active than other styles, and certain offenses may be “overlooked” on a variety of social, legal, and cultural grounds, as long as the public order is maintained. Smith and Cole comment the broad discretion exercised in this style of policing can result in charges of discrimination, when it appears police treatment of different groups results in the perception that some groups get better treatment than others;


  • Legalistic. Emphasizes law enforcement and professionalism. This is usually found in reform-minded cities, with mixed socioeconomic composition. Officers are expected to generate a large number of arrests and citations, and act as if there were a single community standard for conduct, rather than different standards for different groups. However, the fact that certain groups are more likely to have law enforcement contact means this strict enforcement of laws may seem overly harsh on certain groups;


  • Service. Emphasizes the service functions of police work, usually found in suburban, middle-class communities where residents demand individual treatment. Police in homogeneous communities can view their work as protecting their citizens against “outsiders”, with frequent but often-informal interventions against community members. The uniform make-up of the community means crimes are usually more obvious, and therefore less frequent, leaving police free to deal with service functions, and traffic control.


Wilson’s study applies to police behavior for the entire department, over time. At any given time, police officers may be acting in a watchman, service, or legalistic function by nature of what they’re doing at the time, or temperament, or mood. Individual officers may also be inclined to one style or another, regardless of supervisor or citizen demands.

, fingerprinting, drug testing, a polygraph examination and consultation with a psychologist are common practices used to review the suitability of candidates. Recruiting in most departments is competitive, with more suitable and desirable candidates accepted over lesser ones, and failure to meet some minimum standards disqualifying a candidate entirely. Departments maintain records of past applicants under review, and refer to them in the case of either reapplication or requests from other agencies.

Despite these safeguards, some departments have at times relaxed hiring and staffing policies, sometimes in violation of the law, most often in the cases of local departments and federally-funded drug task forces facing staffing shortages, attrition, and needs to quickly fill positions. This has included at times the fielding (and sometimes the arming) of uncertified officers (who may be working temporarily in what is supposed to be a provisional limited-duty status prior to certification) and the hiring of itinerant "gypsy cops"
