Megan's Law

Megan's Law is an informal name for laws in the United States requiring law enforcement authorities to make information available to the public regarding registered sex offenders, which was created in response to the murder of Megan Kanka. Individual states decide what information will be made available and how it should be disseminated. Commonly included information are the offender's name, picture, address, incarceration date, and nature of crime. The information is often displayed on free public websites, but can be published in newspapers, distributed in pamphlets, or through various other means.

At the federal level, Megan's Law is known as the Sexual Offender (Jacob Wetterling) Act of 1994, and requires persons convicted of sex crimes against children to notify local law enforcement of any change of address or employment after release from custody (prison or psychiatric facility). The notification requirement may be imposed for a fixed period of time - usually at least ten years - or permanently.

Some states may legislate registration for all sex crimes, even if no minors were involved. It is a felony in most jurisdictions to fail to register or fail to update information.

Megan's Law provides two major information services to the public: sex offender registration and community notification. The details of what is provided as part of sex offender registration and how community notification is handled vary from state to state, and in some states the required registration information and community notification protocols have changed many times since Megan's Law was passed. The Adam Walsh Child Protection and Safety Act supplements Megan's Law with new registration requirements and a three-tier system for classifying sex offenders according to their risk to the community.
