Metropolitan Police Department, Washington D.C.

On the morning of Monday, September 16, 2013, Aaron Alexis entered Building 197 at the Washington Navy Yard, where he served as an independent contractor, and carried out the most deadly workplace mass shooting in the Nation’s Capital in recent memory.

Over the course of 69 minutes, Alexis terrorized thousands of employees of Naval Sea Systems Command, firing indiscriminately from a shotgun he had legally purchased two days earlier and a handgun he had taken from a security guard after mortally wounding the guard. He would also get into multiple shooting engagements with responding law enforcement officers, seriously injuring a Metropolitan Police Department (MPD) officer. In his final confrontation with police, Alexis ambushed and fired upon another MPD officer. Fortunately, the officer was saved by his protective vest and was able to return fire, killing Alexis and ending his rampage. When it was over, Alexis had shot and killed twelve people and injured several others.

*****

In the aftermath of the incident, the members of MPD first and foremost want to remember and honor the twelve people who lost their lives. Twelve people went to work that Monday, but did not return home to their loved ones. It is truly a senseless tragedy beyond comprehension, and there are no words adequate enough to express our condolences. Our thoughts remain with the victims’ families and friends.

This research offers the largest and most comprehensive database ever created on lone wolf terrorism, along with a theory-informed case study component based on direct contact with imprisoned lone wolf terrorists, and a comparative analysis distinguishing lone wolves from those who undergo radicalization in a group setting. Strictly in terms of lethality, the data indicate that lone wolf terrorism in America is not on the rise. Although lone wolf terrorism may not be increasing, it is undergoing two important changes in modus operandi. First, uniformed police and military personnel have become the primary target of lone wolf terrorists. Second, consistent with the relaxation of U.S. gun laws since the 1990s and the recent trend in mass shootings, the lone wolf’s preferred weaponry is now a staggering range of high-velocity firearms. While there is no standard profile of the lone wolf terrorist, most of them are unemployed, single white males with a criminal record. Compared to members of terrorist groups, lone wolves are older, less educated and more prone to mental illness.

The study validates a series of commonalities associated with pathways to radicalization for lone wolf terrorists. The radicalization model indicates that lone wolf terrorism begins with a combination of personal and political grievances which form the basis for an affinity with online sympathizers. This is followed by the identification of an enabler, followed by the broadcasting of terrorist intent. The final commonality is a triggering event, or the catalyst for terrorism. The ability of law enforcement and intelligence communities to detect and prevent lone wolf terrorism demands a clear understanding of these radicalization processes. Such insight may provide investigators with a sort of detection system, or “signatures”—as minimal as they may appear—that an individual with a terrorist intent will demonstrate in preparing for an attack. Crucial to this understanding is the broadcasting of intent. While lone wolves physically isolate from society, at the same time they seek recognition for their causes through spoken statements and threats, manifestos, e-mail messages, texting and videotaped proclamations. Focusing on this kind of immediate objective of radicalization among lone wolves, rather than on their underlying grievances, may sharpen our focus on the dangers posed by lone wolf terrorism.

Domestic and foreign violent extremist organizations, or terrorist groups, have caused a greater amount of harm with chemical agents than with biological or radiological weapons. The United States capacity and capability to identify, prevent, counter, and respond adequately to chemical threats is established by the strategies, policies, and laws enacted across multiple levels of government. While the number of chemical terrorism incidents has risen and fallen over time, there is no empirical or analytical indication that the threat is disappearing. This report comes at a time when the nation's highest-level strategies have shifted from focusing primarily on violent extremist organizations to focusing more on Great Power Competition. This shift in relative perceived threat and consequent prioritization will impact efforts against chemical terrorism, and in turn, affect funding priorities. Revised risk assessments are needed to reprioritize risks guided by new strategies, so that strategy-aligned budgets can be created. The report recommends weapons of mass destruction budgets be aligned with evolving priorities and incentivize activities that transition promising research to operations.

This open access book outlines the latest results in analysing, assessing, and managing terrorist risk in the urban outdoor built environment. In detail, contents refer to the outdoor Open Areas (such as streets, squares, urban parks and other public spaces in our cities) exposed to such violent events considering the physical elements and properties of the built environment and users. PThe built environment features, including layout, use and management, are combined with terrorist threats issues and user behaviours in emergency conditions, to determine a set of complementary tools for the reduction of risk and increase of urban resilience. The contents hence provide different levels of tool analysis, for risk scenario definition, risk assessment, mitigation strategies design and effectiveness evaluation, considering traditional approaches about the issue along with simulation-based approaches relying on understanding and representing user behaviors. This “behavioural design” approach offers the opportunity to manage the level of risk for specific real urban cases overcoming the normative limitations in Europe that are only referred to a few countries and sometimes deal with the prevention of violent acts by intelligence activities as the exclusive way to face this issue. In addition, the focus on the characters of cultural and historic places and their resilience is increasing by means of introduction of mitigation and compatible solutions providing a complementary chapter for the design of resilient cities in all of their peculiarities (peripheries, consolidated, and historical). In this sense, it is one of the first organized attempts to analyse the main limitations of current solutions in these outdoor Open Areas and, at the same time, to clearly introduce the importance of human behaviours and the various choices in emergency evacuation conditions, thanks to the proposed behavioural-based simulation approach. The attention is focused on a critical aspect for historic spaces, where morphological conditions are fixed values. Thus, this book represents a sort of guidelines about these user-related issues during such violent events and is useful to both professionals and researchers in the areas of security and urban administration.

Although only 8 percent of the world lives in Latin America and the Caribbean (LAC), the region accounts for a third of all homicides worldwide. LAC cities consistently top international rankings as some of the most violent locales outside of active conflict zones. Behind this insecurity are powerful and deeply entrenched transnational criminal organizations (TCOs) trafficking drugs and other illegal commodities, who in turn rely on a seemingly endless flow of illicit firearms to carry out their campaigns of violence and intimidation on the Western Hemisphere’s inhabitants. Arms trafficking goes well beyond a law enforcement challenge; the proliferation of semi- and fully automatic rifles, grenade launchers, and various high-caliber weapons are increasingly used by TCOs to hold at risk the very sovereignty of LAC governments. Stories from Mexico, Haiti, Ecuador, and beyond all underscore how the scourge of illicit weapons, and the groups who wield them, can plunge communities, and even whole countries, into violence.

Leveraging new data sources, this report examines the prevalence and patterns of arms trafficking within and between each of the four subregions. Recognizing the nature of the threat arms trafficking presents to the Western Hemisphere at large, the report seeks to define the contours of a new strategy to combat illegal guns, concluding with recommendations for the United States, Mexico, Central America, South America, and the Caribbean to pursue.

This report examines trends and patterns in firearm violence from 1993 to 2023 using a combination of data sources to provide a broad perspective on fatal and nonfatal firearm violence in the Unites States that could not be achieved through any single source of information. It includes data on firearm type; incident location; victim and offender demographic characteristics and relationship; injury and treatment type; police notification; and victims’ self-protective behaviors.

Estimates in this report are based primarily on data from BJS’s National Crime Victimization Survey and the Centers for Disease Control and Prevention’s (CDC) National Vital Statistics System death certificate data queried through the Web-based Injury Statistics Query and Reporting System. Additional estimates come from the CDC’s National Violent Death Reporting System, National Syndromic Surveillance Program, and Youth Risk Behavior Survey. The report is organized to present findings from each data source in separate sections.

Highlights

• The rate of nonfatal firearm violence for persons age 12 or older declined 72% from 1993 to 2023, dropping from 7.3 to 2.0 victimizations per 1,000 persons, and varied from 1.2 to 2.3 per 1,000 during 2019 to 2023.

• About 64% of nonfatal firearm violence was reported to police during 2018–2022.

• The firearm homicide rate among persons age 12 or older fluctuated between 1993 and 2023, with a decline from 1993 to 2014 (from 8.4 to 4.0 homicides per 100,000 persons age 12 or older) before rising to 7.3 per 100,000 in 2021.

• From 2018 to 2022, on average, 80% of homicides were committed with a firearm

This paper seeks to examine the array of terrorist designations undertaken by “Five-Eye” (FVEY) countries (i.e. Australia, Canada, New Zealand, the United Kingdom, and the United States) against violent far-right terrorists, often also referred as racially and ethnically motivated violent extremist (REMVE) actors. While not a focus of the papers, non-FVEY countries, most notably Germany, have also implemented measures to restrict the activities of violent far-right actors. Thus, this paper will evaluate whether non-FVEY measures can help inform broader policy determinations related to violent far-right terrorism designations. What lessons learned, if any, can the FVEY countries draw from other national experiences? Furthermore, are there multilateral regimes, such as the United Nations Security Council Resolution (UNSCR) 1267 counterterrorism sanctions regime (henceforth, 1267 regime), that can inform FVEY policies within the field of terrorist designations?

We study the effect of mass shooting exposure on individuals’ mental health by using the Panel Study of Income Dynamics. Our identification strategy relies on the quasi-randomness of mass shootings in a staggered difference-in-differences design. We compare changes in mental health outcomes of individuals living in affected cities with changes of matched individuals living in non-proximal and not affected cities. We find that mass shootings have a substantial adverse impact on mental health, which persists for up to six years. This impact is not statistically significant for Black individuals, whereas it is slightly more pronounced among women and older cohorts

This project expands the Profiles of Individual Radicalization in the United States (PIRUS) database with information on the nexus of criminal extremism and U.S. military service. The expanded database includes 461 individuals with U.S. military backgrounds who committed criminal acts in the United States from 1990 through 2021 that were motivated by their political, economic, social, or religious goals. Findings from these data are detailed in three results sections of a report that can be accessed here.

The first section explores the scope and nature of criminal extremism in the ranks, detailing the rates of military service among criminal extremists and analyzing their military branch, ideological, and extremist group affiliations. This section also provides a closer look at the individuals with military backgrounds who have been charged with criminal offenses related to the Capitol breach of January 6, 2021.

Section two provides a closer look at risk factors for radicalization, comparing subjects with military backgrounds to those without records of military service. This section explores the rates of substance use disorders, anti-social relationships, and social mobility challenges among past U.S. service members who committed extremist crimes and situates these radicalization risk factors within the larger extremist context in the United States.

The final section of results examines the risk factors and vulnerabilities for radicalization that are unique to subgroups of criminal extremists with U.S. military backgrounds. Using hierarchical clustering methods, the results in this section show how the radicalization pathways of extremists with military backgrounds are likely to differ depending on whether individuals are active in the military at the time of their involvement in extremism or if they have military-specific risk factors for radicalization, such as previous deployments to combat zones or diagnoses of post-traumatic stress disorder (PTSD). This report concludes with recommendations for policy and future research, paying particular attention to the potential benefits of applying a public health model to countering the spread of extremism in the U.S. military.

Trafficking in persons is a global challenge that transcends borders, and the advent of AI technologies has the potential to amplify both its reach and complexity. It is precisely this global nature of both trafficking and AI that necessitates coordinated, regional, and international responses. The Organization for Security and Co-operation in Europe (OSCE) and the Regional Support Office of the Bali Process (RSO) have jointly developed this brief on the emerging nexus of artificial intelligence (AI), trafficking in persons, and transnational crime with a clear objective: to equip policymakers, law enforcement agencies, and the technology sector with the insights needed to anticipate and pre-emptively address the potential implications of AI on trafficking in persons.

The literature focusing on gender and radicalisation has steadily increased over the last ten years. This has reflected the rise of extremism across the globe, and has been particularly triggered by researchers seeking to better understand the experiences of individuals throughout all stages of the radicalisation process. However, research on the topic has also largely focused on the experiences of women, especially those associated with Islamist forms of extremism. Such narrow focus has resulted in several gaps in the literature, which in turn has translated into gaps in practice. This report seeks to identify the key trends in research between 2014 and 2024 concerning literature on gender and radicalisation, as well as make explicit the areas that remain underexplored. Focusing on tangible recommendations, which align with the needs of practitioners, the report seeks to bring forward the state of the art of research on gender and radicalisation.

Despite the fact that research indicates that it is important to integrate a gender-based approach for effective risk assessment and implementation of counter-terrorism (CT) and preventing and countering violent extremism (P/CVE) practices, such as rehabilitation and reintegration, our assessment of academic and grey literature on gender perspectives in CT and P/CVE practices shows that most of these practices remain gender-blind and tend to reproduce gender norms and stereotypes, while ignoring the complexity of women’s and men’s involvement in extremism. In this report, the authors did a thorough literature review of academic and grey literature published between 2014 and 2024, and conducted ten interviews to reflect on gender perspectives in CT and P/CVE practices. After a reflection on persisting gender construction, biases, and other problematic perspectives, the report focuses on the gender perspectives in analytical frameworks and toolkits used, for instance, for risk assessments. Next, the report elaborates on the gender perspectives in the implementation of the intervention phases, namely from law enforcement interventions, to exit processes. In the general conclusion, the authors argue that gender constructs, roles, and norms, and the way these are taken into consideration in the various P/CVE interventions, heavily impact the effectiveness of these efforts. They also conclude that there is a potential of an aggravating sequence of gender (mis)conceptions, since the gender constructs used in the risk assessments inform following interventions, such as disengagement, deradicalisation, and rehabilitation processes. The report ends with a set of recommendations tailored to different target groups.

 Deaths due to firearm violence occur in alarming numbers in the United States (U.S.) each year. In 2023, over 43,000 people died from a firearm-related injury, and the majority (55%) of these deaths were from suicide (Gun Violence Archive, 2024). Young people are at heightened risk, with firearms being the leading cause of death for youth ages 13-24, and the cause of half of all suicide deaths in this age group as well (Centers for Disease Control and Prevention, 2024; National Violent Death Reporting System, 2024). Only in the last five years did Congress allocate federal resources for firearm violence research, and the prior decades-long ban on this research has stymied information that could have been used to prevent these deaths (Hellman, 2019). This lack of research has had wide-reaching effects, including the limited understanding of how firearm violence impacts specific vulnerable populations, such as LGBTQ+ individuals. Although much progress has been made, systematic data collection efforts that assess LGBTQ+ identity and experiences have long been a challenge in the U.S., similarly limiting available research on LGBTQ+ health and wellness (Healthy People 2030, 2023). One of the most consistent findings we do know from available research, however, is that LGBTQ+ young people experience higher rates of considering and attempting suicide compared to their peers. The Trevor Project’s 2024 U.S. National Survey on the Mental Health of LGBTQ+ Young People found that 39% of all LGBTQ+ young people seriously considered attempting suicide in the past year. This finding is important in the context of what we know about firearms: they are the most lethal means used in suicide attempts; nearly 9 in 10 (89.6%) suicide attempts with a firearm result in death (Conner, Azrael, & Miller, 2019). Furthermore, though mass shootings constitute a small fraction (1.5%) of firearm deaths in the U.S., the public nature of this violence, often targeted toward members of oppressed groups, still have noteworthy impact. Mass shootings are defined by The Federal Bureau of Investigation (FBI) as any incident in which four or more people are shot and wounded or killed, excluding the shooter. Many LGBTQ+ people across the country identified with the victims of two widely publicized mass shootings that occurred at LGBTQ+ nightclubs in recent years: the Pulse shooting in 2016, and the shooting at Club Q in 2022. The mental health of survivors and directly impacted geographic communities are adversely affected by mass shootings (Lowe & Galea, 2017), and individuals not directly affected by mass shooting events can  also experience post-traumatic stress through media exposure (Thompson et al., 2019). In the instance of the Pulse shooting, those who identified as LGBTQ+ responded more strongly to media coverage and, in turn, experienced more post-traumatic stress (First et al., 2023). Everytown for Gun Safety states that not only is addressing firearms essential to any strategy to reduce suicide, but also that the effect of mass shootings extends to survivors, families, and communities. Despite the elevated risk of suicide attempts among LGBTQ+ young people, the fact that the majority of firearm deaths in the U.S. are suicides, and the high lethality of suicide attempts involving firearms, little is known about how many LGBTQ+ young people own or have access to firearms, or how experiences of mass shooting events impact suicide risk. Using data from the 2024 U.S. National Survey on the Mental Health of LGBTQ+ Young people, this brief examines relationships between access to firearms, the impact of mass shootings, and suicide risk among LGBTQ+ young people. Results Access to Firearms Overall, 40% of LGBTQ+ young people reported that there was a firearm in their home. The majority (92%) of those with a firearm in the home reported that it was not theirs. Additionally, of those who reported the presence of a firearm in their home, 63% reported that the firearm was kept in a locked place, 22% reported that it was not kept in a locked place, and 15% reported that they did not know whether it was kept in a locked place. Demographics LGBTQ+ young people ages 13-17 reported higher rates of having a firearm in their home (44%), compared to their LGBTQ+ young people ages 18-24 (36%). LGBTQ+ young people living in the South reported the highest rates of having a firearm in their home (48%), followed by LGBTQ+ young people living in the Midwest (43%), West (37%), and Northeast (25%). Cisgender boys and men reported the highest rates of living in a home with a firearm (46%), followed by transgender girls and women (43%), transgender boys and men (42%), nonbinary youth (38%), youth questioning their gender identity (38%), and cisgender girls and women (36%). Native and Indigenous LGBTQ+ young people reported the highest rates of living in a home with a firearm (58%), followed by White LGBTQ+ young people (45%), Multiracial LGBTQ+ young people (38%), Black LGBTQ+ young people (31%), Latinx LGBTQ+ young people (29%), Middle Eastern and North African LGBTQ+ young people (22%), and Asian American and Pacific Islander LGBTQ+ young people (21%). No significant differences were found in rates of having a firearm in the home when comparing LGBTQ+ youth based on their socioeconomic status  LGBTQ+ young people who reported the presence of a firearm in their home reported higher rates of having seriously considered suicide in the past year (43%), compared to their LGBTQ+ peers who did not report a firearm in their home (37%). Reporting the presence of a firearm in the home was associated with 19% higher odds of seriously considering suicide in the past year (adjusted odds ratio [aOR] = 1.19, 95% Confidence Interval [CI] = 1.11-1.28, p < 0.001), compared to LGBTQ+ young people who did not report the presence of a firearm in the home. LGBTQ+ young people who reported having a firearm in their home had higher rates of attempting suicide in the past year (13%), compared to their LGBTQ+ peers who did not report having a firearm in their home (11%). The presence of a firearm in the home was associated with 17% higher odds of reporting a suicide attempt in the past year (aOR = 1.17, 95% CI = 1.05-1.30, p < 0.01), Among LGBTQ+ young people who reported having a firearm in their home, 48% of those who did not keep it in a locked place and 46% of those who did not know if it was kept in a locked place seriously considered suicide in the last year, compared to the 40% who said the firearms were kept in a locked place (p<.001). Similarly, among those LGBTQ+ young people who reported the presence of a firearm in their home, 14% of those who did not keep it in a locked place and 15% of those who did not know if it was kept in a locked place attempted suicide in the last year, compared to the 12% who said the firearms were kept in a locked place (p<.001).

Aum Shinrikyō’s sarin attack on the Tokyo subway in March 1995 left an indelible mark on Japanese society. This book is the first comprehensive study of the competing memories of Aum Shinrikyō’s religious terrorism. Developing a sociological framework for how uneven distributions of power and resources shape commemorative processes, this book explores how the Aum Affair developed as a ‘cultural trauma’ in Japanese collective memory following the Tokyo attack. The book shows how numerous stakeholders, including the state, the mass media, public intellectuals, victims, and perpetrators offered competing narratives about the causes and consequences of Aum’s violence. Combining multiple methods including media content analysis, participant observation, and original interviews with victims and ex-members, this book reveals various flashpoints of contention such as the state regulation of religion, ‘brainwashing’ and ‘mind control’ controversies, and the morality of capital punishment. It shows that although cultural trauma construction requires the use of moral binaries such as ‘good vs.. evil’ and ‘sacred vs.. profane’, the entrenchment of such binary codes in commemorative processes can ultimately hinder social repair and reconciliation.

This literature review examines cross-disciplinary work on radicalization to situate, historicize, frame, and better understand the present concerns around online radicalization and far-right extremist and fringe movements. We find that research on radicalization is inextricably linked to the post-9/11 context in which it emerged, and as a result is overly focused on studying the other. Applying this research to the spread of far-right ideas online does not account for the ways in which the far-right’s endorsement of white supremacy and racism holds historical, normative precedent in the United States. Further, radicalization research is rife with uncertainties, ranging from definitional ambiguity to an inability to identify any simplistic, causal models capable of fully explaining the conditions under which radicalization occurs. Instead, there are multiple possible pathways to radicalization, and while the internet does not cause individuals to adopt far-right extremist or fringe beliefs, some technological affordances may aid adoption of these beliefs through gradual processes of socialization. We conclude that the term “radicalization” does not serve as a useful analytical frame for studying the spread of far-right and fringe ideas online. Instead, potential analytical frameworks better suited to studying these phenomena include theories prominent in the study of online communities, conversion, mainstreaming, and sociotechnical theories of media effects.

A summary of key take-aways includes:

The adoption of extremist, far-right, and fringe beliefs is often referred to as “radicalization,” a term formulated post-9/11 to understand jihadi terrorism, a very different context from the far-right.

Radicalization research is full of uncertainty.

• No specific type of person is vulnerable to radicalization, and most people who commit political violence are not mentally ill or alienated from society.

• Radicalization is not caused by poverty, oppression, or marginalization.

• There is no one way in which people are “radicalized.”

• Viewing extremist media does not necessarily lead to adopting extremist beliefs or committing political violence.

In contrast to the “red pill” model, radicalization is gradual. Recruits slowly adopt the identities, emotions, and interpretations shared by a community. They conceptualize their problems as injustices caused by others, and justify using political violence against them.

The internet does not cause radicalization, but it helps spread extremist ideas, enables people interested in these ideas to form communities, and mainstreams conspiracy theories and distrust in institutions.

"Radicalization” is not a useful frame for understanding the spread of far-right and fringe ideas online.

• It is analytically imprecise and morally judgmentalIt doesn’t help us understand the role of media and digital technologies.

• It is inextricably tied to a global security infrastructure targeting Islam.

• It doesn’t account for the fact that fringe or far-right beliefs may change what people think is “true” and “false,” making it hard to find common ground.

• The focus on violence ignores other worrying effects of mainstreaming far-right and fringe ideas.

This report outlines gun death data from 2022, the most recent year of finalized data available. All data were accessed using the Centers for Disease Control’s Underlying Cause of Death database, part of the Wide-ranging Online Data for Epidemiologic Research (WONDER) database. The Underlying Cause of Death database contains data based on death certificates for U.S. residents and is the most reliable national source of gun death data available in the U.S. The gun death data used from this database depicts injury mortality by intent using the following categories: homicide, suicide, unintentional, legal intervention, and undetermined. Rates are calculated by the residence listed of decedent, not where the shooting actually took place. For simplification purposes, we created the following age categories to examine gun violence centered on youth: children (ages 1–9) and teens (10–17). For smaller, specific age ranges, we created the following categories: older teens (15–17) and emerging adults (17–19).

Precise figures about the numbers of illegal firearms in the European Union (EU) are lacking, but several indicators point to their widespread availability and accessibility. According to the Small Arms Survey, over half of the estimated total number of firearms held by civilians in the EU in 2017 were unlicensed. While most of these citizens had no criminal intentions, their illicit firearms could be used for self-harm or domestic violence, or end up in the hands of criminals or terrorists. Most criminals and terrorists have more sophisticated ways to get hold of illicit firearms. They can be trafficked from source countries, diverted from legal supply chains, illegally manufactured or assembled in the EU, converted from legally available weapons, or sourced on the internet. Firearms seizures suggest that the EU illicit firearms market is made up mostly of shotguns, pistols and rifles, with converted or convertible weapons also appearing frequently. Illicit firearms trafficking is driven by criminal demand, with organised crime groups that engage in firearms trafficking also involved in other forms of criminality. The EU considers illicit firearms a key crime threat precisely because they are used in many crimes and terrorist attacks. Even people who lack extensive criminal connections can access illicit firearms due to increased online trafficking and the availability of easy-to-convert weapons. The EU is actively involved in addressing the threat posed by illegal firearms by means of legislative and policy measures, and provides operational assistance to the Member States in the fight against firearms trafficking. The EU is also active in the international fight against firearms trafficking, working closely with the United Nations (UN) in its work to combat the proliferation of small arms and light weapons and engaging in the UN's global firearms programme. Although the export of arms remains a national competence, the EU has defined common rules governing the control of exports of military technology and equipment and works actively with third countries that are viewed as source or transit countries for illicit firearms. This is an update of a briefing by Ann Neville, published in 2022.
