Career-of-the-Month: Law Enforcement Officer

The goal of law enforcement is to promote public safety and welfare. A law enforcement officer (also called peace officer) is any public-sector employee or agent whose duties involve enforcing laws, collecting evidence, and catching criminals. They may be employed by local, special, State or Federal agencies.

Law enforcement officers include police officers, prison officers, customs officers, immigration officers, constables, bailiffs, probation officers, parole officers, arson investigators, auxiliary officers, state troopers, sheriffs, marshals, and their deputies – basically anyone “sworn, badged, and armable” who can make an arrest, or refer such arrest for a criminal prosecution.

In the majority of states in the U.S., actively-employed state-certified peace officers, regardless of the capacity in which they are employed (private, public, company, security, campus, etc.), have the ability to pursue and apprehend someone suspected of committing a felony outside of their normal jurisdiction.

In the United States, sheriffs and police officers perform very different functions, although both are considered law enforcement and the two organizations may cooperate. The word “sheriff” derives from the Old English concept of a “shire reeve,” a man who looked out for the interests of the King in a shire, or district, of England. Since at least the 1600s in America, the term “sheriff” has been used to refer to a law enforcement officer.

The word “police” comes from the ancient Greek term “polissoos,” which referred to a person who was guarding a city. In the late 1600s and early 1700s, men who patrolled a “beat” enforcing local laws began to emerge, and they became known as policemen. One of the first truly organized police forces was the Metropolitan Police in London.

In contrast to a Sheriff, who in most states is elected by the voters of a county, a Chief of Police is usually a municipal employee who owes his or her allegiance to a city or town. But perhaps the most significant division in law enforcement is between police and detectives. Most police officers wear uniforms. However, detectives often work in regular clothes. Many detectives are part of regular police forces, but they usually have separate duties from police officers.

Specialized preventive and detective personnel exist within many law enforcement organizations either for dealing with particular types of crime, such as traffic law enforcement and crash investigation, homicide, or fraud; or for situations requiring specialized skills, such as underwater search, aviation, explosive device disposal (“bomb squad”), and computer crime.

Many larger jurisdictions also employ specially selected and trained quasi-military units armed with military-grade weapons for the purposes of dealing with particularly violent situations beyond the capability of a patrol officer response, including high-risk warrant service, hostage situations, barricaded suspects, and riots. In the United States these units are commonly known as SWAT (Special Weapons And Tactics) teams.

Although they wear different uniforms, the hiring requirements of all law enforcement officers – which require admission to and completion of academy training – are generally similar. For example, in addition to being a high school graduate, an applicant must have: stamina to sit, stand, or walk for long periods of time; strength to subdue persons; dexterity to fire a handgun; tolerance to work under adverse conditions; and the knowledge, skills, and abilities necessary to do the work. Law enforcement candidates often have military experience, college training in police science, or a bachelor’s degree in law enforcement or another related field such as Criminal Justice or Sociology.

Candidates must take a written exam, submit to a physical exam, and undergo a background check. They may also be required to take a psychological exam and polygraph exam. If the candidate passes all of these tests, he or she is interviewed; and if the interview goes well, the candidate is sent to a training academy. At the academy, the cadet will participate in an academic program which is designed to prepare them for active duty. The trainee will learn how to handle firearms, drive a law enforcement vehicle, and perform other necessary tasks. After graduation, the candidate is accepted into the department where he or she interviewed. An applicant may also attend an academy and then apply into a department, although this tends to be more rare.

Government Special Agent hiring (ATF, DEA, FBI, etc.) is fiercely competitive, with typically less than 5% of qualified applicants being selected. They must possess at minimum a four year bachelor degree and competitive work experience (which is usually four or more years at a local or state police department). Applicants must pass a rigorous background check in order to achieve, at minimum, a top secret clearance.

Law enforcement work is challenging and offers people an opportunity to serve their communities. Law enforcement officers usually work on foot or ride in cars, but a few ride horses, bikes, or motorcycles. Some work in boats on rivers and in harbors. Some law enforcement officers work with dogs. Law enforcement officers must be healthy, strong, and of good character. They take big risks when chasing criminals or when they go to make an arrest. Good training, teamwork, and equipment help keep law enforcement officers safe.
