"This report summarizes the Department's accomplishments during this Administration to fight human trafficking through aggressive, proactive investigations that reflect a victim-centered approach. Victims are essential to the investigation, prosecution, and prevention of this appalling crime. Our strategy is multi-disciplinary. We promote effective federal and state laws, sophisticated investigatory techniques, and tough federal and state prosecutions that work collaboratively with federally supported crime victim services and outreach programs. Because trafficking knows no borders, our efforts have also involved the international community, where we have shared our victim-centered approach with foreign nations."
