Washington State's Community Protection Act includes a provision allowing public officials to warn communities about potentially dangerous sex offenders when they are released from incarceration. The statute does not specify how dangerousness is to be assessed, nor does it establish methods for notification. Local jurisdictions, therefore, have implemented the law in a variety of ways. This paper describes how local jurisdictions determine, with assistance from the state, which sex offenders are dangerous, and how they notify the public. A sample of jurisdictions were contacted to ascertain their decision-making procedures and costs.
