You have been asked to support the Los Angeles Police Department (LAPD) by analyzing their crime data to identify patterns in criminal behavior. They plan to use your insights to allocate resources effectively to tackle various crimes in different areas.

You are free to use any methodologies that you like in order to produce your insights.
