This partial image came from FamilyWatchDog.com. The whole image shows 20 registered sex offenders in the San Ramon Valley. I was a little surprised by this.

We’ve used this blog in the past to alert the community about sex offenders and we wanted to let people know about this site developed by John Walsh from America's Most Wanted.

Enter your street address and a map will pop up with your house as a small icon. There will be red, blue, green and yellow dots surrounding your entire neighborhood. When you click on these dots a picture of a criminal will appear with his/her home address and the description of the crime committed.

The best thing is you can show your children these pictures and see how close these people live to your home or school.
