The Community Protection Act was implemented in Washington State in March 1990. One of the provisions of the Act, known as the community notification law, authorizes local law enforcement agencies to disseminate information to the public regarding convicted sex offenders who reside in the community. Washington State's community notification law was the first of its kind in the nation. Several other states have now enacted similar laws. This report provides the first examination of how the community notification law has been implemented in Washington State, who has been affected by it, and its impact on recidivism among sex offenders who were subjects of the law.
