Answer 2

The following is written by and according to the U.S. Department of Labor and particular to the work of a police officer.

People depend on police officers and detectives to protect their lives and property. Law enforcement officers, some of whom are State or Federal special agents or inspectors, perform these duties in a variety of ways depending on the size and type of their organization. In most jurisdictions, they are expected to exercise authority when necessary, whether on or off duty.
Police and detectives pursue and apprehend individuals who break the law and then issue citations or give warnings. A large proportion of their time is spent writing reports and maintaining records of incidents they encounter. Most police officers patrol their jurisdictions and investigate any suspicious activity they notice. Detectives, who are often called agents or special agents, perform investigative duties such as gathering facts and collecting evidence.
The daily activities of police and detectives differ depending on their occupational specialty-such as police officer, game warden, or detective-and whether they are working 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.
Uniformed police officers have general law enforcement duties, including maintaining regular patrols and responding to calls for service. Much of their time is spent responding to calls and doing paperwork. They may direct traffic at the scene of an accident, investigate a burglary, or give first aid to an accident victim. In large police departments, officers usually are assigned to a specific type of duty. Many urban police agencies are involved in community policing-a practice in which an officer builds relationships with the citizens of local neighborhoods and mobilizes the public to help fight crime.
Police agencies are usually organized into geographic districts, with uniformed officers assigned to patrol a specific area such as part of the business district or outlying residential neighborhoods. Officers may work alone, but in large agencies, they often patrol with a partner. While on patrol, officers attempt to become thoroughly familiar with their patrol area and remain alert for anything unusual. Suspicious circumstances and hazards to public safety are investigated or noted, and officers are dispatched to individual calls for assistance within their district. During their shift, they may identify, pursue, and arrest suspected criminals; resolve problems within the community; and enforce traffic laws.
Some agencies have special geographic jurisdictions and enforcement responsibilities. Public college and university police forces, public school district police, and agencies serving transportation systems and facilities are examples. Most law enforcement workers in special agencies are uniformed officers; a smaller number are investigators.
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. (For information on other officers who work in jails and prisons, see correctional officers elsewhere in the Handbook.)
Sheriffs and deputy sheriffs enforce the law on the county level. Sheriffs are usually 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
State police officers, sometimes called 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 are frequently called upon to render assistance to other law enforcement agencies, especially those in rural areas or small towns.
State law enforcement agencies operate in every State except Hawaii. Most full-time sworn personnel are uniformed officers who regularly patrol and respond to calls for service. Others work as investigators, perform court-related duties, or carry out administrative or other assignments.
Detectives 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 and State and Federal agents and inspectors 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.
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.
The Federal Government works in many areas of law enforcement. Federal Bureau of Investigation (FBI) agents are the Government's principal investigators, responsible for investigating violations of more than 200 categories of Federal law and conducting sensitive national security investigations. Agents may conduct surveillance, monitor court-authorized wiretaps, examine business records, investigate white-collar crime, or participate in sensitive undercover assignments. The FBI investigates a wide range of criminal activity, including organized crime, public corruption, financial crime, bank robbery, kidnapping, terrorism, espionage, drug trafficking, and cyber crime.
There are many other Federal agencies that enforce particular types of laws. U.S. Drug Enforcement Administration (DEA) agentsenforce laws and regulations relating to illegal drugs. U.S. marshals and deputy marshals protect 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 also 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 entrance to 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 Marshalsprovide air security by guarding against attacks targeting U.S. aircraft, passengers, and crews. U.S. Secret Service special agents and U.S. Secret Service uniformed officersprotect the President, 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.
Work environment. Police and detective work can be very dangerous and stressful. In addition to the obvious dangers of confrontations with criminals, police officers and detectives need to be constantly alert and ready to deal appropriately with a number of other threatening situations. Many law enforcement officers witness death and suffering resulting from accidents and criminal behavior. A career in law enforcement may take a toll on their private lives.
The jobs of some Federal agents such as U.S. Secret Service and DEA special agents require extensive travel, often on very short notice. They may relocate a number of times over the course of their careers. Some special agents in agencies such as the U.S. Border Patrol work outdoors in rugged terrain for long periods and in all kinds of weather.
Uniformed officers, detectives, agents, and inspectors are usually scheduled to work 40-hour weeks, but paid overtime is common. Shift work is necessary because protection must be provided around the clock. Junior officers frequently work weekends, holidays, and nights. Police officers and detectives are required to work whenever they are needed and may work long hours during investigations. Officers in most jurisdictions, whether on or off duty, are expected to be armed and to exercise their authority when necessary.

They fight crime by keeping watch over the town. Special sorts of police like CSI look over the crime scene and find out 'who did what'. Also, police officers spend a lot of time at court for witnessing. Police stop drug dealing, fixed gambling games (E.g Three Card Monte or Find The Pretty Lady), and murder.

The polices job is to enforce the law in their jurisdiction. There are local police, state police, and federal police. Local police usually watch over a city or county and are tasked with your average thugs. State police usually manage highways and deal with criminals wanted throughout the state. Federal is someone who's employed by the us government. They are usually tasked with white collar and dangerous criminals wanted throughout the country. There's also SWAT, which is an elite group of police that specialize in anti terrorism and hostage rescue.
