Law Enforcement Resources

Law enforcement professionals are more likely to encounter dangerous extremists than virtually any other segment of American society — and those confrontations are, tragically, sometimes fatal.

Law enforcement professionals are more likely to encounter dangerous extremists than virtually any other segment of American society — and those confrontations are, tragically, sometimes fatal. In fact, a 2010 University of Maryland study found that 49 of more than 400 people killed by radical-right extremists since 1990, or nearly 15%, have been law enforcement officers. With that in mind, the SPLC has undertaken a number of initiatives to equip officers with information and other resources that may help them carry out their duties with a minimum of danger to themselves.

Our free law enforcement trainings teach officers how to recognize hate groups, symbols and activity; the threat potential of specific groups; and how to respond to hate group activity. The Extremist Files contains updated biographical profiles of leading hate groups and extremist leaders, plus background on the various extremist ideologies. And our Hate Map helps officials locate extremist groups within their communities.

'Lone Wolf' Terrorists 

Violent attacks by “lone wolf” extremists have claimed many lives in recent years – none more than the June 17, 2015, attack on the historic Emanuel A.M.E. Church in Charleston, S.C., where nine African-American worshipers were shot to death by a white supremacist. 

Research by the Southern Poverty Law Center shows that, of 63 domestic terrorism attacks, plots and other incidents of extremist violence between April 2009 and February 2015, three-quarters were the work of a single person acting without the support of a group. Nine out of 10 were carried out by no more than two people. Because of the few number of people involved, these kinds of plots are the most difficult for law enforcement to detect in advance. The 12-minute video below is designed to help law enforcement better understand this threat and how to combat it.

White Supremacist Prison Gangs

Members of white supremacist, or “Aryan,” prison gangs – which operate both inside and outside prison walls – pose a serious threat to correctional and law enforcement officers. On March 19, 2013, the head of Colorado’s prison system was assassinated at his home. The suspected gunman, who was later killed in a police shootout in Texas after wounding a deputy and crashing his car during a chase, was a member of such a gang. He was the second member of Crew 211 to die in a confrontation with law enforcement within a 13-month span.

Below is a 15-minute training video produced by the SPLC to help officers understand the structure of these gangs, their criminal enterprises and the signs, such as distinctive tattoos, that they can use to identify members’ affiliations. Other SPLC resources are also listed.
