Detectives & Criminal Investigators

Video transcript: skip transcript

Whether on foot, wheels, or horseback, detectives and police officers are alert for any threat to public safety, ready to respond at a moment’s notice when a need occurs. Police and sheriff’s officers protect lives and property. They respond to emergency and patrol their assigned area for signs of criminal activity. They wear recognizable uniforms, and may conduct searches and arrest suspected criminals. Some officers specialize in one type of crime, such as narcotics. Detectives and criminal investigators, or agents, gather facts and evidence of possible crimes. They conduct interviews, observe the activities of suspects, and participate in raids and arrests. Detectives often wear plain clothes, and usually specialize in investigating one type of crime, such as homicide or fraud. Transit and railroad police patrol railroad yards and transit stations to prevent thefts and protect property. Police and detective work requires patience, and paperwork; officers document every incident in detail, and must be ready to testify in court. Most officers carry law enforcement tools, such as radios, handcuffs, and firearms. Police and detective work can be physically demanding, stressful, and dangerous; injuries are common. Despite working shifts around the clock and dealing with life-threatening situations, officers must stay calm, think clearly, and use good judgment at all times. Most positions require graduation from a law enforcement agency’s training academy and extensive on-the-job training. Police officers and detectives need a license to carry firearms and enforce the law. Typically, candidates must be U.S. citizens, at least 21 years old, and in excellent physical and mental health, with no felony convictions.
