Whether investigating a murder or burglary, giving first aid, stopping a fight, or simply patrolling an area to prevent crime, few people are more vital to everyone's safety and wellbeing than police officers and detectives. Patrol-car police however, are only one part of the story. Some officers work behind the scenes as experts in fire-arms identification, handwriting and fingerprints, or microscopic analysis. Others are members of special emergency response teams.
After three to five years of experience, some police officers may be promoted to detective. Operating as plainclothes investigators, detectives gather facts and collect evidence for criminal cases. They interview witnesses, examine written records, conduct suspect surveillance, and interrogate prisoners.
