No one want to buy a home where has lots of crime

By looking at this LA county crime data layer, some area such as south gate almost has no crime ???? While area next to it has huge amount of crime !!!

Why is that ?

Possible reason why ?

Los Angeles county crime scene location is only in unincorporated county area. Not inside of any cities, is true or not?

Cities has city police. Cities crime data should not on county crime data. County police not work on city land, only work on unincorporated county area, isn't ?

Is this true or not ? Let's find out 

To prove this concept you will need 2 layers, 

1. county crime data layer (has crime location point)

2. cities boundary layers ( have unincorporated area boundary )

You will need add label to city boundary layers as city name.
