If you go to this website and punch in your street address, city, state, and zip it will show you a map of your neighborhood and if there is a registered sex offender, rapist, etc. in your area they show up as red, yellow, or blue dots. You would be surprised. I have a guy living three houses down who was convicted of Molestation in '94!!!
