Detectives are specialized law enforcement officers who investigate crimes and gather evidence to solve cases. They often work on serious offenses, such as homicides, thefts, and fraud. Detectives use various techniques, including interviewing witnesses, analyzing physical evidence, and reviewing surveillance footage, to piece together what happened. In many police departments, detectives are promoted from the rank of patrol officers after gaining experience. They may work in different units, such as homicide, narcotics, or cybercrime, depending on their expertise. Their goal is to uncover the truth and bring criminals to justice while ensuring public safety.
