Megan’s law

an amendment to the Jacob Wetterling Crimes Against Children and Sexually Violent Offender Registration Act requiring that state registries of convicted but released sex offenders be disseminated to the public so that communities will be notified of offenders’ presence in a particular neighborhood.
