From the Anti-Defamation League:
Extremism and terrorism contributed to the deaths of at least 69 people in the United States in 2016, a slight increase from the 65 deaths attributed to violent extremism in 2015, according to a new report from the Anti-Defamation League. That figure establishes 2016 as the second deadliest year for domestic extremist related deaths in the U.S. since 1970, the earliest year for which ADL maintains such data.
The report, “Murder and Extremism in the United States in 2016,” provides an annual snapshot of extremist violence from ADL’s Center on Extremism. The fatalities reported last year include 49 people killed in the June 2016 shooting spree at the Pulse nightclub by terrorist Omar Mateen, who pledged allegiance to ISIS and referred to the Boston Marathon bombers during the attack. That attack alone was the deadliest domestic terrorist incident since the Oklahoma City bombing in 1995 and overshadowed all other extremist acts.
