Family Watchdog allows you to see where registered sexual offenders live and work around you and your family.Information contained on this site provides no representation as to any offender's likelihood of re-offending or the nature of any future crimes they may commit.Harassment, stalking, or threatening anyone on this list likely violates your state law and is neither condoned nor encouraged by Family Watchdog, its directors or employees.The information that is used to report on this site derives from official public records.Some of the official data is gathered from the offenders themselves who are required by law to report their current address to law enforcement officials.They recently published their findings in a report, "Estimating the Size and Structure of the Underground Commercial Sex Economy in Eight Major US Cities." The researchers interviewed pimps and sex workers in eight different cities.Their findings are not comprehensive -- they left out major cities like New York and Los Angeles, for example.
