This study of Megan's Law contrasts scholarly narratives that describe and analyze sexual predator laws with a case study of implementation in New Jersey. A critical feminist perspective shows that Megan's Law employs a radically underinclusive notion of sexual violence that conflicts sharply with feminist arguments about the cultural and institutional roots of sexual violence. The law excludes many of the most common offenders from reach of the law, thus deflecting attention away from assaults committed by family and friends in favor of reviving stereotypes about deviant strangers. The most significant effect of Megan's Law is not to expand the power of the punitive state but to advance a political and legal interpretation of rape that undermines the basis for and gains made by feminist rape law reforms of the 1970s.
