One of the organizations that sponsors these trainings is the Anti-Defamation League (ADL). The ADL is a non-profit that works to combat anti-Semitism and advocate for Israel. In this context, the ADL runs a National Counter-Terrorism Seminar that has sent hundreds of top ranking officials to Israel to learn about combatting terror since 2003. That same year the ADL established an Advanced Training School that brings delegations of Israeli law enforcement to speak to American law enforcement officials, involving over 1,000 U.S. participants since the program began.
The Police Department of Wellesley, Massachusetts, is among the departments that have sent delegates to Israel. Terrence M. Cunningham has served as Chief of Wellesley Police Department since 1999. Chief Cunningham attended a training in Israel with the ADL as a delegate of the National Counter-Terrorism Seminar in November 2014. Chief Cunningham serves as Deputy Executive Director of the International Association of Chiefs of Police since 2017.
