Mass killings linked to extremism spiked

The number of U.S. mass killings linked to extremism over the past decade was at least three times higher than the total from any other 10year period since the 1970s, according to a report by the Antidefamation League.

The report, provided to The Associated Press ahead of its public release Thursday, also found that all extremist killings identified in 2022 were linked to right-wing extremism, with an especially high number linked to white supremacy. They include a racist mass shooting at a supermarket in Buffalo, New York, that left 10 Black shoppers dead and a mass shooting that killed five people at an LGBTQ nightclub in Colorado Springs.

“It is not an exaggeration to say that we live in an age of extremist mass killings,” the report from the group’s Center on Extremism says.

Between two and seven domestic extremism-related mass killings occurred every decade from the 1970s to the 2000s, but in the 2010s that number skyrocketed to 21, the report found.

The trend has since continued with five domestic extremist mass killings in 2021 and 2022, as many as there were during the first decade of the new millennium.

The number of victims has risen as well. Between 2010 and 2020, 164 people died in ideological extremist-related mass killings, according to the report. That’s much more than in any other decade except the 1990s, when the bombing of a federal building in Oklahoma City killed 168 people. Extremist killings are those carried out by people with ties to extreme movements and ideologies.
