On a regular basis, news stories appear in the media about public shootings where shooters use their guns to open fire and kill people in shopping malls or on school campuses. Mostly these stories deal with incidents in the United States. Over the last years, however, a number of European countries have experienced similar public shooting incidents. Notable cases were the shootings at Tuusula and Kauhajoki in Finland (2007 and 2008), the killings in Cumbria in the UK (2010), the Utøya attacks by Anders Breivik in Norway (2011), and the shootings at Alphen aan den Rijn in the Netherlands and Liège in Belgium in 2011. Public shootings draw a high level of media attention. Less striking in the public eye, but not less significant – not least in quantitative terms –, are the numbers of people in Europe killed by firearms in the context of gun-related crime or in domestic shootings.

Recent demonstrations and violent attacks have highlighted the need for an improved understanding of the role of internet-based technologies in aiding and amplifying the spread of extremist ideologies. Since the early days of the internet, radical groups and movements across the ideological spectrum have demonstrated their intent and ability to harness virtual platforms to perform critical functions.

This Perspective, the second in a RAND Corporation series on online white-supremacist and violent misogynist material, provides a primer on how the internet influences the activities of radical groups and movements and how exposure to or consumption of extremist content online influences the behavior of internet users. After briefly discussing relevant terminology, the authors describe the role of the internet in facilitating five operational functions for radical groups and movements: (1) group financing; (2) networking and coordination; (3) recruitment and radicalization; (4) inter- and intra-group knowledge transfer; and (5) planning, coordination, and execution of harmful online and offline operations. The authors then examine how virtual interactions can facilitate or encourage users' adoption of extremist ideas and inspire or alter offline behavior. The Perspective concludes with a discussion of how the internet can be leveraged as a tool to counter extremism, and the authors provide suggestions for further research.

Terrorism and ideologically inspired violence represent persistent and serious threats to U.S. national security. The January 6, 2021, attack at the U.S. Capitol and other recent events emphasize the need for more research to inform prevention and deradicalization strategies. In this report, the authors aim to characterize why and how individuals joined extremist organizations, as well as how some of them exited these groups. Semistructured interviews were conducted with former extremists and their family members, representing 32 unique stories of 24 white supremacists and eight Islamic extremists.

Exposure to propaganda on the internet, in music, and in books and literature was present in more than two-thirds of the sample. Although formal, top-down recruitment occurred for three Islamic extremists, the majority of white supremacists actively sought out participation in extremist organizations. Among the sample, 26 had exited the organizations; of those, six were still undergoing cognitive and emotional deradicalization. Among those who exited, 22 mentioned that a person or group intervened to help them by providing diverse cultural and demographic exposures, emotional support, financial stability, or domestic stability.

Interviewees also addressed such systemic issues as unemployment and the need for more-affordable and easily accessible mental health care. These interviews led to recommendations for both research and practice that emphasize the importance of incorporating the voices of those with personal experience and knowledge of ideological extremism into future research designs and efforts to prevent radicalization and promote deradicalization.

Racially or ethnically motivated violent extremism (REMVE) and extremists (REMVEs) present some of the most pressing threats to the United States. REMVE also has been identified as the White identity terrorist movement (WITM). REMVEs are among the most lethal domestic violent extremists, and they are the most likely to commit mass-casualty attacks. These movements are characterized by a broad ideological orientation toward xenophobic, anti-Semitic, racist, and misogynistic sentiment.

For this report, the authors reviewed the relevant literature on REMVE networks and collected and analyzed social media data from six social networks (Twitter, Reddit, Gab, Ruqqus, Telegram, and Stormfront) to produce a global network map of the digital REMVE space. That network map evaluates each network's construction, connectivity, geographic location, references to prominent organizations, and proclivity to violence. The authors also reviewed ten countries' experiences with REMVE to sketch out an understanding of the REMVE space in these countries and how REMVEs in those countries relate to those in the United States.

To support the U.S. Department of Defense (DoD)'s efforts to counter extremism in its ranks, the authors considered how a terrorism prevention or countering violent extremism framework might address the issue. They offer intervention initiatives that DoD might consider adopting. They also review the terrorism prevention framework as it has been applied in the U.S. civilian sector and focus on initiatives that might be relevant and adaptable to the military context.

This review highlights broader evidence for such initiatives, places the initiatives in the context of the radicalization process and in the context of other such initiatives, and offers at least a cursory review of the evidence base for interventions.

Extreme right-wing violence and terrorism are a growing threat to Western societies. This form of political violence is also quite elusive and differs from others (e.g. jihadist violence) in some key characteristics. Since the September 11 attacks, policy makers, law enforcement and intelligence agencies as well as researchers have focused most of their attention on Islamic extremist violence and terrorism. This has led to an imbalance in the understanding of other threats, especially from the far-right, and adequate ways to counter it. This paper, using Germany as a main case study, argues that far-right violence has a potential risk of being misunderstood and under-classified, thus creating the perception among victims of that violence that democratic countries “are blind on the right side”. This erosion of trust in the rule of law and the monopoly of force is one goal of extreme right-wing terrorists. Specific recommendations to improve countering the threat posed by the far-right are avoiding double standards in dealing with political violence at all costs, swift and efficient appropriate legal actions against extreme right perpetrators of violence, an increase in funding for research about right-wing terrorism, a possible refinement of the legal definition of “terrorism” and a discussion about its relationship with “hate crimes”, as well as wide scale support for countering violent extremism (CVE) and deradicalisation programs targeting the far-right.

For this Initial Report, the Commission emphasized two major priorities—what happened leading up to the shooting and the law enforcement response. Knowing the true and accurate facts about all the contributing variables leading up to the massacre of February 14 was critical for forming a body of knowledge about certain topics (for example active shooter policies) and enabled the Commission to have a baseline from which to make informed and deliberative recommendations. Further, this knowledge allowed the Commission to make findings that are necessary to drive change. The Commission’s effort is far from complete; all areas require further investigation and recommendations, which the Commission will continue to work on in 2019. This Initial Report establishes the facts and timeline of “what” occurred on February 14, 2018. The more complicated question of “how” it happened and how it became one of the largest school mass killing events in United States’ history is more difficult because of many varied contributing causes. The causes include Cruz’s mental and behavioral health issues, people not reporting warning signs or reporting signs that were not acted on by those to whom actionable information was reported, and how Cruz’s behavioral and discipline issues were addressed (or not addressed) by Broward County Public Schools. Also contributing, was the overall lack of adequate or effective physical site security and unenforced or non-existent security measures and policies at MSDHS, as well as the ineffective behavioral threat assessment process at MSDHS.

This is the interim report of the Investigative Committee on the Robb Elementary Shooting of the Texas House of Representatives. Conscious of the desire of the Uvalde community and the public at large to receive an accurate account of the tragedy at Robb Elementary School, the Committee has worked diligently and with care to issue this interim report of its factual findings. The Committee’s work is not complete. We do not have access to all material witnesses. Medical examiners have not yet issued any reports about their findings, and multiple other investigations remain ongoing. The Committee believes this interim report constitutes the most complete telling to date of the events of and leading to the May 24, 2022, tragedy. This Committee has prioritized factual accuracy, as will be evident from our attention to conducting our own interviews and documenting our sources of information. Still, based on the experiences of past mass-shooting events, we understand some aspects of these interim findings may be disputed or disproven in the future. The Committee issues this interim report now, believing the victims, their families, and the entire Uvalde community have already waited too long for answers and transparency.

An Active Shooter is an individual actively engaged in killing or attempting to kill people in a confined and populated area; in most cases, active shooters use firearms(s) and there is no pattern or method to their selection of victims. Active shooter situations are unpredictable and evolve quickly. Typically, the immediate deployment of law enforcement is required to stop the shooting and mitigate harm to victims. Because active shooter situations are often over within 10 to 15 minutes, before law enforcement arrives on the scene, individuals must be prepared both mentally and physically to deal with an active shooter situation.

On December 14, 2012, one of the most vicious and incomprehensible domestic attacks in American history occurred at Sandy Hook Elementary School in Newtown, Connecticut. Within a few hours, the world understood the gravity of the attack. Lives were lost in two distinct locations: Sandy Hook Elementary School and a private residence in Newtown. The scope of the tragedy would take on international proportions, and people from around the world would grieve and mourn alongside the families of Newtown.

The May 24, 2022, mass shooting at Robb Elementary School in Uvalde, TX, where 19 fourth grade students and two of their teachers were killed and 17 others were injured, reignited a national discourse about preparing school communities for similar tragedies. Proposals ranging from armed teachers to clear backpacks were circulated, despite the lack of empirical evidence to support their efficacy in situations like Uvalde. This leaves an important question for stakeholders charged with keeping school communities safe: what is the best way to reduce the harm caused by these events that is evidence-based?.

Despite the widespread use of lockdown drills in US schools, the conversation about their efficacy remains contentious and often is not guided by empirical evidence. This brief provides an overview of the scholarly evidence surrounding lockdown drills, as well as considerations of best practices, an important foundation for policymakers tasked with keeping students and staff safe and for the public to better understand their utility in schools.
