Homes listed here in Trulia in that area will have a map in the listing. Above the map will be a tab with the word Crimes on it. Click on that tab and you will get some idea what the crime level is in any area. You can click on the + or - on the map to zoom in or out. At the bottom of the map will be a list of specific crimes as well as breaking them down to violent or nonviolent.
I hope this helps.
