Someone sent me this link, a real eye opener. It works for the USA.

find out who lives in your neighborhood.
We have a newstation that not only keep track of sex offenders in our town, but every offenders regardless of how big or small the charges are. If there's a rumor that an offender lives in my street, I look it up. We may have offenders here but we also have pretty good people that keeps an eye out for us and lets us know if there is an offender in town.
This is the one I use. I signed up and receive an e-mail every time one moves in our area. It also shows amber alerts. http://www.scanusa.com/
