The duties of a police officer, also known as a law enforcement officer, focus on protecting people and property. They patrol the areas they are assigned to, which sometimes includes entire jurisdictions, responding to calls, enforce laws, make arrests, issue citations, and occasionally testify in court cases. They often make traffic stops, respond to domestic disturbances, and, at times, provide first aid to someone involved in a traffic accident or injured in a domestic dispute until paramedics arrive. Much of their time is divided between patrolling, writing reports, and filling out forms. duties and responsibilities are prevention of crime, investigation of alert offences and maintenance of law and order.
