The San Diego Association of Governments has developed an excellent website for crime data. They have combined:
1. Crime Maps - enter an address to see crimes reported nearby.
2. Crime Statistics
3, Megan's Law website - locations of sex offenders and maps.
4. San Diego's 10 Most Wanted
5. SD Crime Stoppers - where you can submit anonymous tips
6. Online Warrants and Sheriff's Inmate Log.
Here is the link, and it's included in the right-hand column too:
