"Triangle Center Director David Schanzer and UNC Professor Charles Kurzman present the data supporting their research on homegrown extremism. The key findings of this working paper are: 1) Law enforcement agencies in the United States consider anti-government violent extremists, not radicalized Muslims, to be the most prevalent threat of political violence that they face, 2) they perceive violent extremism to be a much more severe threat nationally than the threat of violent extremism in their own jurisdictions, and 3) a large majority of law enforcement agencies rank the threat of all forms of violent extremism in their own jurisdictions as moderate or lower (3 or less on a 1-5 scale)."
