Every year, individuals with ties to different extreme causes and movements kill people in the United States; the ADL Center on Extremism (COE) tracks these murders. Extremists regularly commit murders in the service of their ideology, to further a group or gang they may belong to, or even while engaging in traditional, non-ideological criminal activities. In 2023, domestic extremists killed at least 17 people in the U.S., in seven separate incidents. This represents a sharp decrease from the 27 extremist-related murders ADL has documented for 2022—which itself was a decrease from the 35 identified in 2021. It continues a trend of fewer extremist-related killings after a five-year span of 47-79 extremist-related murders per year (2015- 2019). One reason for the trend is the decrease in recent years of extremist-related killings by domestic Islamist extremists and left-wing extremists. The 2023 murder totals include two extremist-related shootings sprees, both by white supremacists, which together accounted for 11 of the 17 deaths. A third shooting spree, also by an apparent white supremacist, wounded several people but luckily did not result in fatalities. All the extremist-related murders in 2023 were committed by right-wing extremists of various kinds, with 15 of the 17 killings involving perpetrators or accomplices with white supremacist connections. This is the second year in a row that right-wing extremists have been connected to all identified extremist-related killings. Two of the incidents from 2023 involved women playing some role in the killing or its aftermath. This report includes a special section that examines the role played by women in deadly extremist violence in the United States by analyzing 50 incidents from the past 20 years in which women were involved in some fashion in extremist-related killings.

Every year, individuals with ties to different extreme causes and movements kill people in the United States; the ADL Center on Extremism (COE) tracks these murders. Extremists regularly commit murders in the service of their ideology, in the service of a group or gang they may belong to, or even while engaging in traditional, non-ideological criminal activities. In 2022, domestic extremists killed at least 25 people in the U.S., in 12 separate incidents. This represents a decrease from the 33 extremist-related murders documented in 2021 and is comparable to the 22 extremist-related murders in 2020. It continues the recent trend of fewer extremist-related killings after a five year span of 47-78 extremist-related murders per year (2015-2019). The 2022 murder totals would have been much lower if not for two high-casualty extremist-related shooting sprees. Only 10 of the 25 deaths occurred outside of those sprees—and one of those 10 deaths occurred in a less lethal mass shooting attempt. The issue of extremist-related mass killings is of growing concern and is the subject of a special section of this report. From the 1970s through the 2000s, domestic extremist-related mass killings were relatively uncommon. However, over the past 12 years, their number has greatly increased. Most of these mass killings were committed by right-wing extremists, but left-wing and domestic Islamist extremists were also responsible for incidents. The Center on Extremism has identified 62 extremist-connected mass killing incidents since 1970, with 46 of them being ideologically motivated. Disturbingly, more than half (26, or 57%) of the ideological mass killings have occurred within the past 12 years. Of particular concern in recent years are shootings inspired by white supremacist “accelerationist” propaganda urging such attacks. In 2022, 18 of the 25 extremist-related murders appear to have been committed in whole or part for ideological motives, while the remaining seven murders either have no clear motive or were committed for a non-ideological motive.....

The Turner Diaries, the infamous racist dystopian novel by neo-Nazi William Luther Pierce, has inspired more than 200 murders since its publication in 1978, including the single deadliest act of domestic terrorism in U.S. history, the Oklahoma City bombing. The book is arguably the most important single work of white nationalist propaganda in the English language, but it is not a singular artifact. The Turner Diaries is part of a genre of racist dystopian propaganda dating back to the U.S. Civil War. This paper will document the books that directly and indirectly inspired Turner and examine the extensive violence that the novel has inspired. By comparing and contrasting The Turner Diaries to its less-remembered predecessors, this paper analyses the reasons for the novel’s lasting impact, including its focus on rational choices over identity choices, its simplification of white nationalist ideology, its repeated calls to action, and the powerfully persuasive nature of dystopian narratives, which can be understood as a secular analogue for religious apocalyptic texts.

Every year people with ties to a variety of extreme movements and causes kill people in the United States; the ADL Center on Extremism tracks these murders. Extremists regularly commit murders in the service of their ideology, in the service of a group or gang they may belong to, or while engaging in traditional, non-ideological criminal activities.

In 2021, domestic extremists killed at least 29 people in the United States, in 19 separate incidents. This represents a modest increase from the 23 extremist-related murders documented in 2020 but is far lower than the number of murders committed in any of the five years prior (which ranged from 45 to 78).

The report provides additional insight on perpetrator affiliations, police officer killings, information on the perpetrators and incidents from 2021, an analysis of white supremacist killings in the United States from 2012-2021, and information on the PROTECT plan, ADL’s “seven-part plan to mitigate the threat posed by domestic extremism and domestic terrorism while protecting civil rights and civil liberties.”

What’s new? Research by International Crisis Group has for the first time quantified the positive impact of the UN’s Commission against Impunity in Guatemala (CICIG). This report shows how CICIG’s justice reform activities since 2007 helped contribute to a 5 per cent average annual decrease in murder rates in the country. This compares with a 1 per cent average annual rise among regional peers. Why does it matter? Guatemalan President Jimmy Morales has announced that he will end CICIG’s mandate in 2019. But the commission has won widespread public support in Guatemala for its prosecution of previously untouchable elites. It is a rare example of a successful international effort to strengthen a country’s judicial system and policing. What should be done? With U.S. support for the CICIG under seeming strain, the commission’s other supporters should propose a new deal between the Guatemalan government and the UN based on a revised strategy of case selection and continuing support for political and judicial reforms. The U.S. should wholeheartedly back such a reformulated CICIG.

Every year people with ties to a variety of extreme movements and causes kill people in the United States; the ADL Center on Extremism tracks these murders. Extremists regularly commit murders in the service of their ideology, in the service of a group or gang they may belong to, or while engaging in traditional, non-ideological criminal activities. In 2021, domestic extremists killed at least 29 people in the United States, in 19 separate incidents. This represents a modest increase from the 23 extremist-related murders documented in 2020 but is far lower than the number of murders committed in any of the five years prior (which ranged from 45 to 78). The 2021 murder totals were low primarily because no high-casualty extremist-related shooting spree occurred this past year. Such sprees are the main contributor to high murder totals. Most of the murders (26 of 29) were committed by right-wing extremists, which is usually the case. However, two killings were committed by Black nationalists and one by an Islamist extremist—the latter being the first such killing since 2018. Most of the 2021 murders were committed by people associated with longstanding extremist movements, such as white supremacy and the sovereign citizen movement. However, 2021 continued the trend of recent years of seeing some murders from newer types of extremism, including QAnon adherents, people associated with the toxic masculinity subculture of the “manosphere” and anti-vaccination extremists. White supremacists killed more people in 2021 than any other type of extremist, though not an outright majority, as is often the case. An in-depth look at white supremacist killings over the past 10 years demonstrates the dangers posed by alt right white supremacists and white supremacist prison gangs.
