Researchers from the Urban Institute and Northeastern University examine challenges faced in the investigation and prosecution of human trafficking in the United States. The research targeted counties across the U.S. for a systematic review of human trafficking case records and interviews with police, prosecutors, and service providers. The study found that there was a significant lack of awareness about human trafficking among practitioners and the law enforcement community, as well as a focus on sex trafficking (which is disproportionate to the larger issue of human trafficking).The study provides recommendations to help improve the identification, investigation, and prosecution of human trafficking cases in the United States.
