Advocacy and scholarship addressing sex trafficking as a human rights issue has become a transnational effort, but there has been less attention to sub-national efficacy. Through analyzing progressive justice system responses to domestic violence in Duluth, Minnesota that have been adopted worldwide, this paper demonstrates how to effectively apply these local advances in order to address sex trafficking on a global scale. This paper makes a theoretical contribution to understanding the intersections between domestic abuse and sex trafficking. A key empirical finding is that a coordinated community response (including the justice system and women’s organizations) is crucial for advancing domestic abuse training, monitoring, and legislation—and this coordination can also be productively utilized for improving responsiveness to victims of sex trafficking across a diverse range of socio-legal and economic contexts.
