The year 2020 marks the twentieth anniversary of the United Nations (U.N.) Trafficking Protocol-a treaty that established the foundation for global efforts to address the problem of human trafficking.' That treaty offered an early framing of the problem as a transnational crime, best addressed through aggressive prosecution of traffickers and international cooperation to that end. Since the Protocol's adoption, global antitrafficking law and policy have evolved significantly. The once near-exclusive focus on the prosecution prong of the treaty's "3Ps" approach to trafficking- focused on prosecuting trafficking, protecting trafficked persons, and preventing trafficking-has given way to an increased emphasis on victim protection. Prevention, however, remains the 3Ps' most neglected prong.
