U.S. Gun Violence in 2021: 'An Accounting of a Public Health Crisis'

By Davis, Ari; Kim, Rose; Crifasi, Cassandra K.

From the document: "Gun violence is an ongoing public health crisis in the United States that impacts the health and wellbeing of all of us. [...] Fortunately, there are evidence-based, equitable solutions to prevent gun violence. These solutions are supported by most people, including gun owners. In spite of this wide support, many policymakers have been unwilling to follow the evidence and enact policies that will save lives. Each year it is our mission to provide policymakers and the public accurate and up-to-date data on gun fatalities and illustrate the enormous toll gun violence has on our country. This report is an update of 'A Year in Review: 2020 Gun Deaths in the U.S.' [hyperlink] It uses 2021 firearm fatality data released by the CDC [Centers for Disease Control and Prevention] in January 2023. We recognize that each data point discussed in this report is a person who died by gun violence. This loss has an immeasurable impact on families, friends, and communities; data can only partly illuminate the true burden of gun violence. In addition to analyzing the data, we must listen to and uplift the voices of those directly impacted by gun violence, their loved ones, and their communities. Yet even on its own, the 2021 CDC data paints an alarming picture of the epidemic of gun violence. [...] By leveraging the data outlined in this report, we can improve gun violence prevention strategies and create a more peaceful future, free from gun violence."

Coping with Terrorism: Origins, Escalation, Counterstrategies, and Responses

Edited by Rafael Reuveny and William R. Thompson

Terrorism is imprinted on Western society's consciousness. Nearly every week a terrorist attack occurs in the world. The academic world, in attempting to understand terrorism, has often been limited to descriptive work rather than analysis, and has produced surprisingly few mainstream collections on the subject. Coping with Terrorism offers a collection of essays that ask: who are terrorists, what are their goals, who supports them, and how can we combat their tactics? The essays are scholarly, rather than journalistic or ideological, in their approach. As such, they scrutinize a much-discussed and prevalent subject and bring it into the mainstream for international relations.

Law, Liberty, and the Pursuit of Terrorism

By Roger Douglas

It is commonly believed that a state facing a terrorist threat responds with severe legislation that compromises civil liberties in favour of national security. Roger Douglas compares responses to terrorism by five liberal democracies— the United States, the United Kingdom, Canada, Australia, and New Zealand— over the past 15 years. He examines each nation’s development and implementation of counterterrorism law, specifically in the areas of information gathering, the definition of terrorist offenses, due process for the accused, detention, and torture and other forms of coercive questioning. Douglas finds that terrorist attacks elicit pressures for quick responses, which often allow national governments to accrue additional powers. But emergencies are neither a necessary nor a sufficient condition for such laws, which may persist even after fears have eased. He argues that responses are influenced by institutional interests and prior beliefs and are complicated when the exigencies of office and beliefs point in different directions. He also argues that citizens are wary of government’s impingement on civil liberties and that courts exercise their capacity to restrain the legislative and executive branches. Douglas concludes that the worst anti-terror excesses have taken place outside of, rather than within, the law and that the legacy of 9/11 includes both laws that expand government powers and judicial decisions that limit those very powers.

Promising Approaches for Implementing Extreme Risk Laws: A Guide for Practitioners and Policymakers

By Everytown for Gun Safety and Johns Hopkins Center for Gun Violence Solutions. ( 

Extreme Risk Protection Order (ERPO) laws create an opportunity to intervene and prevent firearm violence when there are warning signs that an individual poses a risk of harm to self or others. While ERPO laws are relatively new, a growing body of research demonstrates the potential for these laws to prevent firearm violence, particularly firearm suicide, and multiple victim/mass shootings. Interest in ERPO laws has increased in recent years, with 16 states having enacted these laws between 2018 and 2023. Implementation varies widely across and within states. As a result of strong ERPO implementation efforts in some jurisdictions, more information is now available for state and local leaders about how to implement and adapt ERPO laws for their own communities. In addition, the Bipartisan Safer Communities Act of 2022 included $750 million in new federal grant funding for states, some of which is designated to support ERPO implementation. To meet this moment, the Everytown for Gun Safety Support Fund and the Johns Hopkins Center for Gun Violence Solutions have partnered to compile this guide of the best available practices and promising approaches to effective implementation of extreme risk laws. These recommendations are informed by conversations with individuals who are pioneering ERPO implementation, in addition to the best practices shared at a December 2022 convening of ERPO leaders from around the country.

Alcohol Misuse and Gun Violence: An Evidence-Based Approach for State Policy

By The  Consortium for Risk-Based Firearm Policy and the Center for Gun Violence Solutions at the Johns Hopkins Bloomberg School of Public Health

  Alcohol use and gun violence are leading causes of preventable injury and death in the United States. Alcohol kills 140,000 people annually;2 guns kill more than 48,000.3 Both of them are public health crises demanding strong policies. These issues are most deadly when they intersect with one another. An estimated 1 in 3 gun homicide perpetrators drank heavily before murdering their victims, 30% of gun homicide victims drank heavily before being killed, and a quarter of gun suicide victims were heavily drinking before they died by suicide.4,5 Despite alcohol clearly being a strong risk factor for gun violence, few attempts have been made to address this intersection. Heavy drinking was involved in: Nearly one third of all gun homicides A quarter of all gun suicides In 2013, the Consortium issued its first policy recommendation related to risky alcohol use and firearm access.i Five years later, the Consortium convened leading experts to reassess this recommendation about firearm prohibitions associated with DUIs as an effective policy measure to prevent firearm-related deaths while ensuring racial equity in enforcement. During the COVID-19 pandemic, excessive drinking increased by 21% and alcohol-related deaths increased approximately 25%.6 At the same time, gun sales increased by 40%, gun homicides by 35%, and gun suicides had the largest one-year increase ever recorded.7,8 These alarming trends urge us to think about alcohol misuse as a risk factor for gun violence. To better understand this connection, the Consortium, in partnership with the Center for Gun Violence Solutions, developed this report to highlight the available research to inform policy. As detailed in this report, alcohol misuse is associated with a risk of dangerous firearm behaviors, interpersonal firearm violence, and gun suicide. Although data about how this dangerous intersection affects different communities is limited, people of color are disproportionately affected by both gun violence and alcohol misuse. This report summarizes the connection between alcohol and firearm use, reviews existing state laws, and makes a core set of recommendations for addressing the problem at the state level: 11 Limiting access to firearms by persons with a record of alcohol misuse 2) 2 Limiting access to guns when and where alcohol is consumed

U.S. Gun Violence in 2021: An Accounting of a Public Health Crisis

By  Ari Davis, Rose Kim, Cassandra Crifasi

  Gun violence is an ongoing public health crisis in the United States that impacts the health and wellbeing of all of us. In 2020, during the first year of the COVID-19 pandemic, the U.S. experienced an unprecedented spike in gun homicides. Many believed that this spike would be short-lived; levels of gun violence would subside as institutions effectively responded to the pandemic and people returned to their daily routines. This, unfortunately, was not the case. In 2021, for the second straight year, gun deaths reached the highest number ever recorded. Nearly 49,000 people died from gun violence in the U.S. in 2021. Each day, an average of 134 people died from gun violence—one death every 11 minutes. Gun homicides continued to rise in 2021, increasing 7.6% over the previous year. Gun suicides reached record levels, increasing 8.3%, the largest one-year increase recorded in over four decades. Guns, once again, were the leading cause of death among children and teens in 2021 accounting for more deaths than COVID-19, car crashes, or cancers. Coincident with the rise in gun-related deaths were record gun sales. Millions of first-time purchasers, including Black and Hispanic/Latino people, and women of all races and ethnicities, bought guns during the pandemic at unprecedented levels. Many of these purchasers were motivated by gun industry marketing claims that guns make you safer. Yet, this is far from the truth; gun ownership greatly increases the risk of dying by suicide and homicide. While it is too early to tell whether this surge in gun purchases contributed directly to the rise in gun violence the country is experiencing, we know that over the long run this influx of guns will only exacerbate the public health crisis of gun violence and worsen health disparities. Fortunately, there are evidence-based, equitable solutions to prevent gun violence. These solutions are supported by most people, including gun owners. In spite of this wide support, many policymakers have been unwilling to follow the evidence and enact policies that will save lives.

Fatal Police Shootings and Race: A Review of the Evidence and Suggestions for Future Research

By Robert VerBruggen  

When the 2014 police shooting of Michael Brown in Ferguson, Missouri, set off riots, we knew very little about the true number of people killed by American law enforcement. But since that time, private actors have stepped up efforts to count such killings comprehensively—and to collect some basic details about each incident. These data, along with agency-specific information furnished by police departments, have facilitated a massive amount of research into an important question: whether there is racial bias in police officers’ use of lethal force. This report summarizes several major lines of work on this question. The simplest studies merely compare racial groups’ rates of police-killing deaths with their rates of crime. Other studies meticulously account for the situational factors of each case, ask whether black officers are less likely than white officers to kill black suspects, analyze police-shooting rates geographically, or even put officers in simulation exercises to see how they respond to suspects of different races.

Ghost guns: spookier than you think they are.

By Garen J. Wintemute

Off-the-books, untraceable “ghost guns” can now be manufactured at home, easily, and in large numbers; they contribute ever more frequently to firearm violence, including hate violence and domestic terrorism. The Bureau of Alcohol, Tobacco, Firearms and Explosives estimates that in 2019 alone, law enforcement agencies recovered more than 10,000 ghost guns. The manuscript describes the current situation and suggests specific actions that state and federal governments can take to avert disaster.

Islamophobia as a Form of Radicalisation: Perspectives on Media, Academia and Socio-political Scapes from Europe and Canada

Edited by Leen d’Haenens and Abdelwahed Mekki-Berrada

Foundations and mechanisms of Islamophobia in the West. Islamophobia as a Form of Radicalisation discusses the scope and fragmented boundaries of Islamophobia as a concept and a sociopolitical reality. The fifteen chapters of this collection cover and connect interdisciplinary research, media content analysis, media discourse analysis, ethnographic research, intersectoral advocacy work, and action research conducted in Belgium, Canada, France, Germany, Poland, Portugal, and Spain. Confronted with an Islamophobia that is growing as a symptom of broader societal malaise in the West, a resistance against it is also arising. It is now a question of better understanding the foundations and mechanisms of this meta-solidarity and resistance. Islamophobia as a Form of Radicalisation offers recommendations for urgent consideration by Muslim citizens of Canada and Europe, media professionals, civil society and academic stakeholders, policymakers at the municipal, provincial and federal levels

Politico-ideological Mobilisation and Violence in the Arab World: All In

By Ahmed Ajil

This book presents a study of politico-ideological mobilisation and violence by focusing on the life stories, trajectories and narratives of individuals who mobilised for causes and conflicts in the Arab World. It provides a greater understanding of the biographical, sociological, political and historic factors pertinent for their radicalisation processes. What makes individuals identify with suffering and injustice, often of others and elsewhere? Why do individuals feel the need to stand up in the first place and how does violent action become a justifiable or necessary course of action? Why and how do they disengage from violence? This book, based on interviews conducted in Lebanon, Switzerland, and Canada, answers these questions. It presents new theoretical insights about politico-ideological mobilisation and violence. By focusing on grievances and grounding analysis in the empirical reality as it is shared and narratively constructed by those who are at the heart of the phenomenon, it moves beyond the moralistic and politicised debates that characterise the field. Interviewees include non-violent and violent engagement for causes and conflicts related to the Arab World, such as sympathisers or members of groups and causes from a variety of ideological orientations, including Shiite militias, Salafi-jihadist groups, radical left-wing groups, Palestine-specific, Kurdish groups, and others such as right-wing or unspecified affiliations. By choosing individuals with different forms of political engagement, both non-violent and violent, and different ideological orientations, it helps readers to get a better grasp of how similar grievances may lead to different outcomes. In focusing on three markedly different geopolitical contexts, the book also provides a cross-contextual understanding of mobilisation for political and violent action. The interviewees also include experts and peripheral actors such as professionals, researchers, policymakers, friends, or family members. Their perspectives complement and enrich some of the findings by providing external yet in-depth ‘expert knowledge’. Politico-ideological Mobilisation and Violence in the Arab World will be of great interest to criminologists, political scientists, sociologists, and other scholars interested in the study of terrorism, radicalisation and extremism. It will also appeal to journalists, policymakers, practitioners working in the field.

Radicalization in Theory and Practice: Understanding Religious Violence in Western Europe

Edited by Thierry Balzacq and Elyamine Settoul  

Radicalization is a major challenge of contemporary global security. It conjures up images of violent ideologies, “homegrown” terrorists and jihad in both the academic sphere and among security and defense experts. While the first instances of religious radicalization were initially limited to second-generation Muslim immigrants, significant changes are currently impacting this phenomenon. Technology is said to amplify the dissemination of radicalism, though there remains uncertainty as to the exact weight of technology on radical behaviors. Moreover, far from being restricted to young men of Muslim heritage suffering from a feeling of social relegation, radicalism concerns a significant number of converted Muslims, women and more heterogeneous profiles (social, academic and geographic), as well as individuals that give the appearance of being fully integrated in the host society. These new and striking dynamics require innovative conceptual lenses. Radicalization in Theory and Practice identifies the mechanisms that explicitly link radical religious beliefs and radical actions. It describes its nature, singles out the mechanisms that enable radicalism to produce its effects, and develops a conceptual architecture to help scholars and policy-makers to address and evaluate radicalism—or what often passes as such. A variety of empirical chapters fed by first-hand data probe the relevance of theoretical perspectives that shape radicalization studies. By giving a prominent role to first-hand empirical investigations, the authors create a new framework of analysis from the ground up. This book enhances the quality of theorizing in this area, consolidates the quality of methodological enquiries, and articulates security studies insights with broader theoretical debates in different fields including sociology, social psychology, economics, and religious studies.

Terrorism in Great Britain: the statistics

By  Grahame Allen, Matthew Burton and Alison Pratt

The beginning of the millennium saw an increased political focus on the threat from international terrorism, heightened by the attack on the Twin Towers on 11 September 2001. Only one year before 9/11, new counter-terrorism legislation had been passed in the UK. Designed to reform and extend state powers found in previous counter-terrorism legislation, the Terrorism Act 2000 gave increased powers to the Home Secretary and the police. It moved the focus of counter-terrorism to all forms of domestic and international terrorism, rather than just Northern Ireland-related terrorism. In 2003, the Government introduced its counter-terrorism strategy, CONTEST. Now in its fourth iteration, CONTEST aims to reduce the risk to the UK from terrorism with four objectives:

  • Pursue: to stop terrorist attacks

  • Prevent: to stop people becoming terrorists or supporting terrorism

  • Protect: to strengthen protection against a terrorist attack

  • Prepare: to mitigate the impact of a terrorist attack

Although statistics relating to terrorism and the use of counter-terrorism legislation have been collected by the Home Office since the 1970s, the publication (and consistent collection) of data was halted in 2001. This briefing examines the available statistics on terrorism in Great Britain including:

  • Deaths due to terrorism

  • The use of stop and search legislation

  • Terrorism arrests

  • Pre-charge detention periods

  • Prosecutions and convictions for terrorism

  • Terrorist prisoners

  • The use of TPIMS

  • The number of foreign fighters fighting in Syria

How to define and tackle Islamist extremism in the UK

By Maaha Elahi and Julian Hargreaves  

This article presents a legal and public policy analysis of Shakeel Begg v British Broadcasting Corporation, a British libel case brought before the High Court in 2016. Begg v BBC provides a lens through which current debates on extremism and counter-extremism in the UK may be analysed. More specifically, the authors use their analysis of the case to address criticisms levied against the UK Government’s counter-extremism strategy, including the conceptualisation and definition of “Islamist extremism”. The article offers two main contentions. First, that the judgment in Begg v BBC has been undervalued by politicians and policymakers in the UK, as well as by scholars, journalists and other commentators. Second, that Lord Justice Haddon-Cave’s judgment in Begg v BBC provides a useful framework for those wishing to define, identify and tackle Islamist extremism, and extremism of any kind, in the UK and elsewhere.

Audit of the Department of Justice’s Strategy to Address the Domestic Violent Extremism Threat

By The United States. Department of Justice. Office of the Inspector General

The objectives of this audit were to: (1) evaluate the Department of Justice’s (DOJ or Department) efforts to develop a comprehensive strategy to address domestic violent extremism (DVE) in the United States, and (2) determine if the Department is effectively coordinating among Department stakeholders on the implementation of its strategy. Our audit scope covered the period of fiscal year (FY) 2017 to FY 2022. Results in Brief DOJ has identified DVE, which it refers to interchangeably as domestic terrorism, as one of the most significant threats facing the country. DOJ has characterized its efforts to counter DVE as a whole-of-Department commitment that requires sustained attention and resources. Nonetheless, DOJ has not formalized a DVE strategy. DOJ has focused attention on investigating, prosecuting, and preventing acts of DVE, but it also has experienced challenges in ensuring that its various efforts are cohesive and used in a strategic way to better identify lessons learned and spread awareness of available resources. Moreover, although DOJ has issued some internal guidance relating to DVE investigations, additional clearer guidance across all law enforcement and litigating components could assist in promoting greater consistency about what qualifies as a DVE case and better coordination in the handling of cases with a DVE nexus. DOJ should also consider formalizing mechanisms to routinely evaluate the efficacy and impact of its DVE efforts and to maintain the continuous protection of civil liberties. Finally, DOJ should improve its coordination on data-driven efforts to consistently track DVE-related cases across the Department

Murder and Extremism in the United States in 2022: Including an In-Depth Analysis of Extremist Mass Killings

By Anti-Defamation League

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.....

Money Laundering and Terrorist Financing Risks Arising from Migrant Smuggling

By The Financial Action Task Force (FATF)

Migrant smuggling is a global issue. Every year, millions of migrants seek to escape regional conflict, political instability, persecution and poverty in search of a better future. They can risk their lives at the hands of migrant smugglers who see them as an opportunity to make financial gains and often have little regard for the migrants’ safety. The proceeds generated by migrant smuggling are estimated to exceed USD10 billion per year.

This FATF report analyses the money laundering and terrorist financing risks associated with migrant smuggling. While there has been an increase in migrant smuggling, many countries do not consider it a high-risk crime for money laundering and the associated financial flows are rarely investigated. 

The report identifies the most common methods to transfer and launder the proceeds of migrant smuggling, from hawala, integration of proceeds into legitimate business such as shops, travel agencies and transport companies, and the increasing use of professional money launderers. Using countries’ experiences, the report provides several recommendations and good practices that allow authorities to better trace criminal proceeds and enhance the effectiveness of money laundering investigations.

The report highlights the need for countries to understand the money laundering risks they face from migrant smuggling and to proactively follow the money linked to this criminal activity, including through increased collaboration with national and international authorities and the private sector.

The FATF calls on countries to proactively follow the money linked to migrant smuggling. Strengthening institutional, international and regional cooperation is an important step. There should be particular focus on supporting countries directly affected by migrant smuggling.

Ethnically or Racially Motivated Terrorism Financing

By The Financial Action Task Force (FATF)

This report focuses on the funding behind ethnically or racially motivated terrorism, also referred to as extreme right-wing terrorism. Extreme right-wing attacks have increased in recent years, highlighting the need to raise awareness about this complex phenomenon and its financing. While most of these attacks were carried out by self-funded lone actors, they can also involve small and medium organisations, as well as transnational extreme right-wing movements. Few countries have designated these groups or individuals as terrorists and there are differences in the countries’ legal regimes to addressing their activities. Extreme right-wing groups can obtain funding from criminal activity, but most funding comes from legal sources, such as donations, membership fees and commercial activities. These groups are becoming increasingly sophisticated in the way they move and use funds and there are growing transnational links between the groups.

The report highlights the challenges in tackling the financing of extreme right-wing terrorism and preventing attacks. These challenges include how countries view the threat, ranging from terrorism, to racially motivated violence. The report encourages countries to continue to develop their understanding of this increasingly transnational criminal activity, including by considering ethnically or racially motivated terrorism financing in their national risk assessments. It also encourages public, private and international partners to work together to identify the threats and exchange best practices on combating ethnically or racially motivated terrorism financing. The findings in this report are based on inputs from around 30 jurisdictions across the FATF Global Network, as well as expertise from the private sector and international bodies partnered with the FATF.

EU Counter-Terrorism Offences: What impact on national legislation and case-law?

To several governments, modern international terrorism cannot be handled adequately within the ordinary criminal justice system. To fight terrorism (including the criminalization of certain “abstract danger”, preparatory activities such as terrorist training, membership in a terrorist organization) more effectively, criminal law had to be adapted.

Association of State-Level Firearm-Related Deaths With Firearm Laws in Neighboring States

By Ye Liu Michael SiegelBisakha Sen

Question  How are states’ firearm laws associated with firearm-related deaths in nearby states?

Findings  In this pooled cross-sectional analysis involving firearm laws and firearm-related deaths from 2000 to 2019 in the 48 contiguous states, a permit requirement for purchasing all firearms had an interstate association with decreased total firearm-related deaths and homicide, whereas the prohibition of firearm possession for individuals who have committed a violent misdemeanor had an interstate association with decreased firearm suicide.

Meaning  These findings suggest that synergic legislative action to implement firearm laws in proximate states may help prevent firearm-related deaths.

Neighbors Do Matter: Between-State Firearm Laws and State Firearm-Related Deaths in the U.S., 2000-2017

By Ye LiuMichael SiegelBisakha Sen 

Introduction: Firearm injury is a major U.S. public health concern. This study aims to evaluate whether the relationship between state firearm laws and state firearm deaths are affected by comparatively lenient firearm laws in neighboring states.

Methods: This observational study used 2000‒2017 data on firearm deaths and firearm laws of the 48 contiguous states of the U.S. (Alaska, Hawaii, and the District of Columbia excluded). The associations among state firearm deaths, state firearm laws, and presence of neighboring states with more lenient laws were analyzed using negative binomial regression models with state- and year-fixed effects. Analyses were conducted in 2019‒2020.

Results: There were 578,022 firearm deaths of all intents during the study period or 11.1 firearm deaths (IQR=8.5-14.0) per 100,000 population. The presence of more state firearm laws was associated with decreased firearm deaths (incident rate ratio=0.991, 95% CI=0.987, 0.996). However, weaker firearm laws in neighboring states correlated with more firearm deaths within a state (incident rate ratio=1.016, 95% CI=1.004, 1.028). Failing to account for weaker laws in neighboring states led to the underestimation of the impact of 1 additional law on state's own firearm deaths (incident rate ratio=0.994, 95% CI=0.989, 0.998 vs 0.991, 95% CI=0.987, 0.996) by approximately 20%.
