Police officers protect lives and property. Detectives and criminal investigators, who are sometimes called agents or special agents, gather facts and collect evidence of possible crimes.
Police officers pursue and apprehend people who break the law. They then warn, cite, or arrest them. Most police officers patrol their jurisdictions and investigate suspicious activity. They also respond to calls, issue traffic tickets, and give first aid to accident victims.
Most Police officers carry law enforcement tools, such as radios, handcuffs, and guns.
