Police officers, detectives, and criminal investigators typically do the following:
- Respond to emergency and nonemergency calls
- Patrol assigned areas
- Conduct traffic stops and issue citations
- Search for vehicle records and warrants using computers in the field
- Obtain warrants and arrest suspects
- Collect and secure evidence from crime scenes
- Observe the activities of suspects
- Write detailed reports and fill out forms
- Prepare cases and testify in court
Job duties differ by employer and function, but all police and detectives write reports and keep detailed records that will be needed if they testify in court. Most carry law enforcement tools, such as radios, handcuffs, and guns.
The following are examples of types of police and detectives:
Detectives and criminal investigators are uniformed or plainclothes investigators who gather facts and collect evidence for criminal cases. They conduct interviews, examine records, observe the activities of suspects, and participate in raids and arrests. Detectives usually specialize in investigating one type of crime, such as homicide or fraud. Detectives are typically assigned cases on a rotating basis and work on them until an arrest and trial are completed or until the case is dropped.
Fish and game wardens enforce fishing, hunting, and boating laws. They patrol fishing and hunting areas, conduct search and rescue operations, investigate complaints and accidents, and educate the public about laws pertaining to the outdoors. Federal fish and game wardens are often referred to as Federal Wildlife Officers.
Police and sheriff’s patrol officers are the most common type of police and detectives, and have general law enforcement duties. They wear uniforms that allow the public to easily recognize them as police officers. They have regular patrols and also respond to emergency and nonemergency calls. During patrols, officers look for signs of criminal activity and may conduct searches and arrest suspected criminals.
Some police officers work only on a specific type of crime, such as narcotics. Officers, especially those working in large departments, may work in special units, such as horseback, motorcycle, canine corps, and special weapons and tactics (SWAT). Typically, officers must work as patrol officers for a certain number of years before they may be appointed to a special unit.
Transit and railroad police patrol railroad yards and transit stations. They protect property, employees, and passengers from crimes such as thefts and robberies. They remove trespassers from railroad and transit properties and check IDs of people who try to enter secure areas.
Communication skills. Police and detectives must be able to speak with people when gathering facts about a crime and to express details about a given incident in writing.
Empathy. Police officers need to understand the perspectives of a wide variety of people in their jurisdiction and have a willingness to help the public.
Good judgment. Police and detectives must be able to determine the best way to solve a wide array of problems quickly.
Leadership skills. Police officers must be comfortable with being a highly visible member of their community, as the public looks to them for assistance in emergency situations.
Perceptiveness. Officers, detectives, and fish and game wardens must be able to anticipate a person’s reactions and understand why people act a certain way.
Physical stamina. Officers and detectives must be in good physical shape, both to pass required tests for entry into the field, and to keep up with the daily rigors of the job.
Physical strength. Police officers must be strong enough to physically apprehend offenders.
