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. Individual states decide what information will be made available and how it should be disseminated. Commonly included information includes the offender's name, picture, address, incarceration date, and nature of crime. The information is often displayed on 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 (or 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.
Here is a recap of the law and amendments since 1994:
1994
The Jacob Wetterling Crimes Against Children and Sexually Violent Offender Registration Act is passed as part of the Federal Violent Crime Control and Law Enforcement Act of 1994. This law requires states to implement a sex offender and crimes against children registry.
1996
Megan's Law amends the Wetterling Act. It requires states to establish a community notification system.
The Pam Lychner Sexual Offender Tracking and Identification Act of 1996 becomes an amendment to the Wetterling Act. It requires lifetime registration for recidivists and offenders who commit certain aggravated offenses.
1998
Provisions contained in Section 115 of the General Provisions of Title I of the Commerce, Justice, and State, the Judiciary, and Related Agencies Appropriations Act (CJSA) amend the requirements of the Wetterling Act to include heightened registration requirements for sexually violent offenders, registration of federal and military offenders, registration of nonresident workers and students, and participation in the National Sex Offender Registry (NSOR).
2000
The Campus Sex Crimes Prevention Act amends the Wetterling Act, requiring offenders to report information regarding any enrollment or employment at an institution of higher education and to provide this information to a law enforcement agency whose jurisdiction includes the institution.
The Supreme Court of the United States has upheld sex offender registration laws twice, in two respects. Two challenges to state laws (in Hawaii and Missouri) have succeeded, however.
In 1947, California became the first state in the United States to have a sex offender registration program. Community notification of the release of sex offenders from incarceration did not occur until almost 50 years later. In 1994, a federal statute called the Jacob Wetterling Act required all states to pass legislation requiring sex offenders to register with state sex offender registries. Then again in 1996, based on a set of New Jersey laws called Megan's Laws, the federal government required states to pass legislation mandating public notification of personal information for certain sex offenders. In Connecticut Dept. of Public Safety v. Doe (2002) the Supreme Court of the United States affirmed this public disclosure.
The Adam Walsh Child Protection and Safety Act became law in 2007. This law implements new uniform requirements for sex offender registration across the states. Highlights of the law are a new national sex offender registry, standardized registration requirements for the states, and new and enhanced criminal offenses related to sex offenders.
In the United States, all 50 states have passed laws requiring sex offenders (especially child sex offenders) to register with police. Accordingly, the law requires offenders report where they take up residence upon leaving prison or being convicted of any crime.
