Nature of the Work

Police officers protect lives and property. Law enforcement officers' duties depend on the size and type of their organizations. Police and detectives pursue and apprehend individuals who break the law and then issue citations or give warnings. Most police officers patrol their jurisdictions and investigate any suspicious activity they notice. They also respond to calls from individuals. Detectives, who often are called agents or special agents, perform investigative duties such as gathering facts and collecting evidence. The daily activities of police and detectives vary with their occupational specialty — such as police officer, game warden, or detective — and whether they work for a local, state, or federal agency. Duties also differ substantially among various federal agencies, which enforce different aspects of the law. Regardless of job duties or location, police officers and detectives at all levels must write reports and maintain meticulous records that will be needed if they testify in court.

Some police officers specialize in a particular field such as chemical and microscopic analysis, training and firearms instruction, or handwriting and fingerprint identification. Others work with special units such as horseback, bicycle, motorcycle, or harbor patrol; canine corps; special weapons and tactics (SWAT); or emergency response teams. A few local and special law enforcement officers primarily perform jail-related duties or work in courts.

Sheriffs and deputy sheriffs enforce the law on the county level. Sheriffs usually are elected to their posts and perform duties similar to those of a local or county police chief. Sheriffs' departments tend to be relatively small, most having fewer than 50 sworn officers. Deputy sheriffs have law enforcement duties similar to those of officers in urban police departments. Police and sheriffs' deputies who provide security in city and county courts are sometimes called bailiffs.

Correctional officers, also known as detention officers when they work in pretrial detention facilities, are responsible for overseeing individuals who have been arrested and are awaiting trial or who have been convicted of a crime and sentenced to serve time in a jail, reformatory, or penitentiary.

Fish and game wardens enforce fishing, hunting, and boating laws. They patrol hunting and fishing areas, conduct search and rescue operations, investigate complaints and accidents, and aid in prosecuting court cases.

Court, municipal, and license clerks perform clerical duties in courts of law, municipalities, and governmental licensing agencies and bureaus. They may prepare dockets of cases to be called; secure information for judges and the court; prepare draft agendas or bylaws for town or city councils; answer official correspondence; keep fiscal records and accounts; issue licenses or permits; and record data, administer tests, or collect fees.

State troopers or highway patrol officers arrest criminals statewide and patrol highways to enforce motor vehicle laws and regulations. State police officers often issue traffic citations to motorists. At the scene of accidents, they may direct traffic, give first aid, and call for emergency equipment. They also write reports used to determine the cause of the accident. State police officers frequently are called upon to render assistance to other law enforcement agencies, especially those in rural areas or small towns.

Officers with the Georgia Bureau of Investigation (GBI) are plainclothes investigators who gather facts and collect evidence for criminal cases. Some are assigned to interagency task forces to combat specific types of crime. They conduct interviews, examine records, observe the activities of suspects, and participate in raids or arrests. Detectives usually specialize in investigating one type of violation such as homicide or fraud. They are assigned cases on a rotating basis and work on them until an arrest and conviction is made or until the case is dropped.

Federal law enforcement encompasses many agencies that enforce particular types of laws. U.S. Drug Enforcement Administration (DEA) agents enforce laws and regulations relating to illegal drugs. U.S. marshals and deputy marshals provide security for the federal courts and ensure the effective operation of the judicial system. Bureau of Alcohol, Tobacco, Firearms, and Explosives agents enforce and investigate violations of federal firearms and explosives laws, as well as federal alcohol and tobacco tax regulations. The U.S. Department of State Bureau of Diplomatic Security special agents are engaged in the battle against terrorism.

The Department of Homeland Security employs numerous law enforcement officers within several different agencies, including Customs and Border Protection, Immigration and Customs Enforcement, and the U.S. Secret Service. U.S. Border Patrol agents protect more than 8,000 miles of international land and water boundaries. Immigration inspectors interview and examine people seeking entry into the United States and its territories. Customs inspectors enforce laws governing imports and exports by inspecting cargo, baggage, and articles worn or carried by people, vessels, vehicles, trains, and aircraft entering or leaving the United States.

Federal air marshals provide air security by guarding against attacks targeting U.S. aircraft, passengers, and crews. U.S. Secret Service special agents and uniformed officers protect the president, the vice president, their immediate families, and other public officials. Secret Service special agents also investigate counterfeiting, forgery of government checks or bonds, and fraudulent use of credit cards. Other federal agencies employ police and special agents with sworn arrest powers and the authority to carry firearms. These agencies include the Postal Service, the Bureau of Indian Affairs Office of Law Enforcement, the Forest Service, and the National Park Service.

Private detectives and investigators assist individuals, businesses, and attorneys by finding and analyzing information. They connect clues to uncover facts about legal, financial, or personal matters. Private detectives and investigators offer many services, including executive, corporate, and celebrity protection; pre-employment verification; and individual background profiles. Some investigate computer crimes, including identity theft, harassing emails, and illegal downloading of copyrighted material. They also provide assistance in criminal and civil liability cases, insurance claims and fraud cases, child custody and protection cases, missing-persons cases, and premarital screening. They are sometimes hired to investigate individuals to prove or disprove infidelity.
