Until 2012, the New Orleans criminal justice system forced persons convicted of certain prostitution offenses to register as sex offenders under an antiquated (1805) statute that criminalizes oral or anal sex in exchange for compensation. This article explores attitudes and beliefs that enabled Louisiana’s misuse of the sex offender registry against primarily indigent African American street-based sex worker women and transgender individuals. Findings presented here derive from a feminist interdisciplinary (cultural anthropology and law) methodological strategy that included qualitative ethnography, quantitative examination of Louisiana’s 64 parish-specific sex offender registries, and legal/policy analysis.
