Here's something I found on the internet, hope it answers the question.

Law enforcement is the group of people tasked with the prevention of crime and apprehension of offenders. As part of law enforcement, police officers have four major responsibilities: enforcing laws, preventing crimes, responding to emergencies, and providing support services.

The primary duty of a police officer is to protect people and property. Common duties of police include controlling traffic, patrolling neighborhoods, responding to emergency calls, writing citations, delivering warrants, arresting violators and submitting incident reports in a timely manner.
