One of the organizations that sponsor 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 Everett, Massachusetts, is among the departments that have sent delegates to Israel. Steve Mazzie has served as Chief of Everett Police Department since 2003. Chief Mazzie attended a training in Israel with the ADL as a delegate of the National Counter Terrorism Seminar in November 2014. His training included high-level briefings on counter-terror operations, airport security, holy site management, and advanced policing technology. He also trained with the Israel National Police, Palestinian Authority Police, and intelligence and security officials.
