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 Chelsea, Massachusetts, is among the departments that have sent delegates to Israel. Brian Kyes has served as Chief of Chelsea Police Department since 2007, a position he remains in today. Chief Kyes attended a training in Israel in November 2014 with the ADL as a delegate of the National Counter-Terrorism Seminar.
