The National Consortium for the Study of Terrorism and Responses to Terrorism (START), a Department of Homeland Security Science and Technology Center of Excellence headquartered at the University of Maryland, has surveyed American law enforcement agencies and found a tectonic shift in their perception of terrorist threats.

The Sovereign Citizen movement was the most highly ranked threat, with 86 percent of respondents agreeing or strongly agreeing that it was a serious terrorist threat. This is a significant increase in ranking from an earlier survey implemented in 2006-2007, which showed Islamist extremists to be law enforcement’s top concern at the time. In that survey, approximately 67 percent agreed or strongly agreed that Islamist extremists were a serious terrorist threat.

The report itself, available here as a PDF file, says that “concern about whether most groups were a serious terrorist threat actually declined for most groups (e.g., the KKK; Christian Identity; Neo-Nazis; Racist Skinheads; Extremist Environmentalists; Extreme Animal Rights Extremists).” In fact, these movements have not appreciably grown in recent years, whereas the sovereign citizen ‘movement’ now boasts hundreds of thousands of adherents.
