Since 2000, the handout notes, 25 law enforcement officers have been killed by right-wing extremists, who share a “fear that government will confiscate firearms” and a “belief in the approaching collapse of government and the economy.”
Despite public anxiety about extremists inspired by Al Qaeda and the Islamic State, the number of violent plots by such individuals has remained very low. Since 9/11, an average of nine American Muslims per year have been involved in an average of six terrorism-related plots against targets in the United States. Most were disrupted, but the 20 plots that were carried out accounted for 50 fatalities over the past 13 and a half years.
In contrast, right-wing extremists averaged 337 attacks per year in the decade after 9/11, causing a total of 254 fatalities, according to a study by Perliger, a professor at the United States Military Academy’s Combating Terrorism Center. The toll has increased since the study was released in 2012.
.. Meanwhile, terrorism of all forms has accounted for a tiny proportion of violence in America. There have been more than 215,000 murders in the United States since 9/11. For every person killed by Muslim extremists, there have been 4,300 homicides from other threats.
