"A survey to be published this week asked 382 police and sheriff’s departments nationwide to rank the three biggest threats from violent extremism in their jurisdiction. About 74 percent listed antigovernment violence, while 39 percent listed “Al Qaeda-inspired” violence, according to the researchers, Charles Kurzman of the University of North Carolina and David Schanzer of Duke University. “Law enforcement agencies around the country have told us the threat from Muslim extremists is not as great as the threat from right-wing extremists,” said Dr. Kurzman, whose study is to be published by the Triangle Center on Terrorism and Homeland Security and the Police Executive Research Forum."
