Right-wing extremism in the United States appears to be growing. The number of terrorist attacks by far-right perpetrators rose over the past decade, more than quadrupling between 2016 and 2017. The recent pipe bombs and the October 27, 2018, synagogue attack in Pittsburgh are symptomatic of this trend. U.S. federal and local agencies need to quickly double down to counter this threat. There has also been a rise in far-right attacks in Europe, jumping 43 percent between 2016 and 2017.

Violent right-wing extremism has resurfaced as a worrying phenomenon in Europe, with terrorism being one of its most serious and visible forms. Old and new forms of right-wing based violence have emerged in recent years, as the Utøya attack showed in 2011. This massacre served as a wake-up call for European societies and security authorities, and highlighted the dangers of right-wing terrorism in Europe, particularly for the youth. Furthermore, terrorism is not the sole form of extreme-right and hate-based violence. Conversely, the range of extreme-right related violence also includes hate crime and hate speech, two phenomena that should not be overlooked. The former is especially relevant considering the impact it has on minority groups, on women, but also on the general population. As for the latter, the increasing use of the Internet and social media platforms has facilitated the exponential dissemination of hate speech. While two decades ago, much more effort was required by individuals to gain access to extremist right-wing ideology, nowadays these ideas are spread at a much higher speed and to a much broader audience. This is not a trivial matter. The spread of hate speech has an important impact on minority groups, as the primary victims, but also on society as a whole, as it affects social cohesion and the quality of democratic debate.

This paper presents a systematic procedure for threat assessment and intervention of school shooters. The model is designed to be used by educators, mental-health professionals, and law-enforcement agencies and is intended to help refine and strengthen the efforts of the National Center for the Analysis of Violent Crime. Its fundamental building blocks are its threat-assessment standards, which provide a framework for evaluating a spoken, written, and symbolic threat, along with a four-pronged assessment approach, which looks at the personality of the student, the student's family dynamics, the school dynamics, the student's role in those dynamics, and social dynamics. The model is not a profile of the school shooter or a checklist of danger signs pointing to the next adolescent who will bring lethal violence to a school. It discusses misinformation about school shootings; how to assess a threat, including motivations; types of threats; factors in threat assessment; and levels of risk. The document cautions that one or two traits or characteristics should not be considered in isolation or given more weight than the others. The text outlines the intervention process and closes with a number of recommendations. Four appendices list methodologies used in the report, suggested readings, and other information. (RJM)

American public schools are safe places, perhaps even safer than American homes. The tragic school shootings that are the focus of this report have occurred in less than one-hundredth of one percent of schools. The probability of being shot at school is similarly low. But shootings have occurred at schools, have been largely unpredictable, and have raised the anxieties and concerns of students, families, teachers, and the public at large. Between 1974 and 2000, the National Threat Assessment Center (NTAC) of the United States Secret Service identified 37 incidents. At least 20 incidents have been reported in the national media since 1992, and eight since 1999, and these do not include several planned shootings that were prevented by authorities. Why do these shootings occur? Why do they occur where they do? What can we do to protect our children?

GAO found that shootings at K-12 schools most commonly resulted from disputes or grievances, for example, between students or staff, or between gangs, although the specific characteristics of school shootings over the past 10 years varied widely, according to GAO’s analysis of the Naval Postgraduate School’s K-12 School Shooting Database. (See figure.) After disputes and grievances, accidental shootings were most common, followed closely by school-targeted shootings, such as those in Parkland, Florida and Santa Fe, Texas.

Mass shootings occur on a regular basis in the United States, and depending on the definitions applied to the shootings an argument can be made that mass shootings of all types occur far more often than what is reported in the media as a “mass shooting.” Unfortunately, school shootings are also part of this analysis of mass shootings, and school shootings in the United States have occurred on a recurring basis since at least 1853. In the modern era, however, school shootings have become more frequent and more deadly as demonstrated by the May 24th, 2022, school shooting in Uvalde, Texas. This heinous crime at Robb Elementary School resulted in the deaths of nineteen children, and two teachers. Although there has been extensive research on mass shooters, mass shootings, and mass shootings in schools, there has not been enough emphasis on the application of homeland javascript:void(0);security principles of target hardening in schools as a risk mitigation factor for mass shootings. In fact, there is much that can be done to keep schools safe through basic target hardening measures, and many of these security updates can be immediately undertaken at the state and local level with relatively minor additional cost to schools and the taxpaying public. This paper references the mass shooting on February 14, 2018, at Marjory Stoneman Douglas High School in Parkland, Florida, and makes policy recommendations toward basic target hardening measures which may be applied as necessary within the public school K-12 environment. The school shooting at Marjory Stoneman Douglas High School was selected due to the fact that it has been recently investigated regarding the facts and circumstances of the incident, and provides ample information for analysis of effective target hardening measures.

In the wake of tragedy in Newtown CT, Congress defined “mass killings” as “3 or more killings in a single incident” (P.L. 112-265). Any consideration of new or existing gun laws that follows mass shootings is likely to generate requests for comprehensive data on the prevalence and deadliness of these incidents. Despite the pathos of mass shootings, only a handful of researchers and journalists have analyzed the principal source of homicide data in the United States—the Supplementary Homicide Reports (SHR) compiled by the Federal Bureau of Investigation (FBI)—to determine whether those incidents have become more prevalent and deadly. According to the FBI, the term “mass murder” has been defined generally as a multiple homicide incident in which four or more victims are murdered, within one event, and in one or more locations in close geographical proximity. Based on this definition, for the purposes of this report, “mass shooting” is defined as a multiple homicide incident in which four or more victims are murdered with firearms, within one event, and in one or more locations in close proximity. Similarly, a “mass public shooting” is defined to mean a multiple homicide incident in which four or more victims are murdered with firearms, within one event, in at least one or more public locations, such as, a workplace, school, restaurant, house of worship, neighborhood, or other public setting. This report analyzes mass shootings for a 15-year period (1999-2013). CRS analysis of the FBI SHR dataset and other research indicates that offenders committed at least 317 mass shootings, murdered 1,554 victims, and nonfatally wounded another 441 victims entirely with firearms during that 15-year period. The prevalence of mass shooting incidents and victim counts fluctuated sporadically from year to year. For the period 2007-2013, the annual averages for both incidents and victim counts were slightly higher than the years from 1999-2007.

This study seeks to understand how women in Kenya are involved in violent extremism and in efforts to prevent and counter it. It also explores how women are affected by and respond to extremism. The findings show the multifaceted impact of violent extremism on women and their communities. There is also a complex set of dynamics that influence how women become actively involved as perpetrators or, more commonly, as supporters and facilitators of violent extremism. The study shows that more must be done to include women in programmes that aim to prevent and counter violent extremism in Kenya.

The self-styled Islamic State is an accident of history, emerging from multiple social, political, and economic tensions in the Middle East and beyond. It has challenged the territorial divisions imposed on the region following the collapse of the Ottoman Empire by carving out for itself a large area of territory.

From Pittsburgh to Poway and Charleston to El Paso, white supremacist extremists (WSEs) pose a clear terrorist threat to the United States. And while extremist groups operating on American soil are often labeled or categorized as domestic terrorist organizations, this report will demonstrate that they maintain links to transnational networks of like-minded organizations and individuals, from Australia, Canada, Russia, South Africa, and elsewhere. The danger of terrorism is growing in the United States, just as it is elsewhere in the world, with white supremacist extremists strengthening transnational networks and even imitating the tactics, techniques, and procedures of groups like al-Qaeda and the Islamic State (IS). These networks share approaches to recruitment, financing, and propaganda, with Ukraine emerging as a hub in the broader network of transnational white supremacy extremism, attracting foreign recruits from all over the world.

Over the past twenty years, al-Qaeda has proven to be resilient and adaptive in its efforts to survive the Global War on Terror (GWOT). Twenty years after the attacks of September 11, 2001 in the United States, perpetrated by al-Qaeda, the organization looks much different than it did at the time. “We are no longer dealing with the same terrorist threat, or even the same al-Qaeda, as we did on September 11,” says Ali Soufan. “What we have today is something more complex and resilient, and an organization that has learned lessons from our policies and counterterrorism approaches. We did a lot to secure the U.S. homeland, but in our handling of the conflicts in Iraq and Afghanistan, we may have shown terrorist groups that all it requires to outlast a superpower is patience.”

This report investigates spatial patterns of terrorism and targeted violence in the United States. Such investigations are rare because terrorist attacks are rare in the United States compared to other nations and the terrorist attacks that do occur are dispersed in similar patterns as population centers. In sum, the relative rarity of attacks, the geographic size of the United States, and the distribution of population density create inherent challenges historically. However, the recent outbreak of political violence throughout the United States coupled with advances in spatial statistics creates an opportunity to investigate emerging patterns at subnational scales.

In 1969 Travis Hirschi published Causes of Delinquency which assessed the status of existing criminological theory and outlined his own version of social bond theory. Hirschi argued, among other things, that criminological theory should focus more on asking “why don’t we do it” rather than the more common question “why do they do it?”(Hirschi, 1969) In this respect, Hirschi advocated for a focus on the constraints or barriers that prevent or reduce the likelihood of crime. The importance of this twist in thinking is the emphasis on the elements of the social fabric, which compel conformity rather than deviation by limiting certain types of human behavior. Following Hirschi, we examine violent radicalization where the expected end point is committing an act of mass casualty terrorism (MCT). For purposes of the current study, MCT can be distinguished from more common types of interpersonal violence along two dimensions (Rutherford et.al., 2007, Tilly 2003). First, as compared to interpersonal violence, which is characterized by close physical proximity between the perpetrator and victim (s), MCT typically involves a greater physical distance between the aggressor and the target (Black, 1996, Senechal de la Roche 1996). Second, MCT typically involves the potential for a large number of fatalities whereas interpersonal violence is much more likely to result in fewer victims (Arnold et.al., 2002, Quillen 2002). Bombings and shooting rampages are common examples of MCT while interpersonal violence includes acts such as fistfights, attacks involving blunt objects (e.g. bats) and stabbings.

This handbook comprises essays by leading scholars and practitioners on the topic of U.S. counterterrorism and irregular warfare campaigns and operations around the globe. Terrorist groups have evolved substantially since 9/11, with the Islamic State often described as a pseudo-state, a terrorist group, and insurgency all at the same time. While researchers', analysts', and policymakers’ understanding of terrorism has grown immensely over the past two decades, similar advancements in the understanding of counterterrorism lag. As such, this handbook explains why it is necessary to take a broader view of counterterrorism which can, and often does, include irregular warfare. The volume is divided into three thematic sections: Part I examines modern terrorism in the Islamic world and gives an overview of the major terrorist groups from the past three decades; Part II provides a wide variety of case studies of counterterrorism and irregular warfare operations, spanning from the 1980s to the irregular warfare campaign against the Islamic State in northern Syria in 2018; Part III examines the government instruments used to combat terrorism and wage irregular warfare, such as drones, Theater Special Operations Commands, and Theater Commands. The handbook fills a gap in the traditional counterterrorism literature by its inclusion of irregular warfare and by providing analyses from academic experts as well as practitioners. It will be of much interest to students of counterterrorism, counterinsurgency, U.S. national security, military affairs, and International Relations.

In this monograph, the authors offer compelling research that reminds government and military officials of the moral, legal, and ethical dimensions of protecting cultural antiquities from looting and illegal trafficking. Internationally, states generally agree on the importance of protecting antiquities, art, and cultural property not only for their historical and artistic importance, but also because such property holds economic, political, and social value for nations and their peoples. Protection is in the common interest because items or sites are linked to the common heritage of mankind. The authors make the point that a principle of international law asserts that cultural or natural elements of humanity’s common heritage should be protected from exploitation and held in trust for future generations. The conflicts in Afghanistan, and especially in Iraq and Syria, coupled with the rise of the Islamic State (IS), have brought renewed attention to the plight of cultural heritage in the Middle East and throughout the world.

Narcoterrorism in Latin America: A Brazilian Perspective builds a case for giving greater attention to the narcoterrorism threat. General Alvaro suggests that security conditions in Colombia and the Tri-Border Area (TBA), where Argentina, Brazil and Paraguay meet, deserve the immediate attention of security officials of the Hemisphere's more capable countries. In this paper, General Alvaro provides a review of Colombia's security situation-the history and current situation-and details his thoughts about the United States' support of the government of Colombian President Alvaro Uribe Velez.
