This resource list is designed to help law enforcement officers find support and assistance dealing with extremist-related crimes. Many law enforcement agencies and professional associations deal with these issues on a regular basis, including more obscure agencies that some may not even realize exist. Yet governmental and private organizations that fight extremist criminal conduct, gang-related activity, and terrorism will be more effective if they are aware of and cooperate with other organizations involved in similar work.

ADL lists these resources for the benefit of law enforcement officers. Most descriptions included below are derived from the agencies or organizations themselves. Inclusion on this list should not be construed to indicate endorsement or agreement with any opinions expressed by any of the included organizations, nor should it be construed as a guarantee of any service offered by these organizations and agencies. ADL welcomes suggestions for additions to this resource list.
