To date, there have been no peer-reviewed studies in the United States estimating the impact of gun-free zone policies in alcohol-serving establishments on rates of firearm violence in and around such establishments. In this study, we utilized a cross-sectional design to estimate the impact of Texas’s 51% alcohol law, which prohibits the carrying of firearms in establishments that generate over half of their revenue from alcohol sales. The analysis focused on the difference in shooting incidents in and around establishments with and without firearm carrying prohibitions in 2021 and 2022. After adjusting for establishment type (bar/restaurant), alcohol sales volume, census tract level demographic factors, and the number of nearby restaurants and bars, results indicated that gun-prohibiting bars experienced significantly fewer shootings compared to those that allowed guns. Specifically, establishments that were gun-prohibited had 37% fewer shootings within 50 m than those that were gun-allowing, with a 95% confidence interval ranging from 60% fewer to 0.2% fewer. This association was more prominent in bars than in restaurants. The protective association with gun-prohibited status diminished with increased distance from the establishments; results were not significant at 100 m. Our study findings align with research suggesting that gun-free zones can reduce firearm violence. However, future studies using quasi-experimental designs that can better support causal inference are needed to support such a conclusion, as are studies exploring the efficacy of such policies in various settings and over longer periods.

Firearm policy in the United States is subject to longstanding political gridlock. Up to now, most of the legal academic literature has focused on the constitutionality of various—or any—regulations regarding firearm possession, sales, or usage. This article inverts the problem and proposes a system for voluntary registration and certification of nonowners, those who want to waive or renounce their Second Amendment rights as a matter of personal conviction. The proposed system is analogous to both the registration of conscientious objectors during wartime conscriptions, and the newer suicide prevention laws whereby individuals can add their names to a do-not-sell list for firearm dealers—though the proposal made here is broader and more permanent. Voluntary registration, with official certification, would serve three important purposes. First, this would help create social identification markers for the gunless-by-choice movement, something that historically has been missing; formal signals and labels of identification with a movement are necessary for a movement’s success, especially with prohibition or abstinence movements. Second, registration and certification as gunless would be a personal moral commitment marker; all societies provide ways for solemnizing one’s vows and solidifying one’s resolve on serious, lifelong moral decisions. Third, certification allows for a market signaling effect, providing useful information that can trigger a beneficial response from the private sector; market responses, in turn, provide useful information about otherwise hotly-debated beliefs, such as whether guns in fact enhance or reduce safety for individuals and public places. This article develops each of these points and offers a unique and simple regulatory and statutory alternative for a new system of registration and certification.

Executive Summary

Gun violence in Guatemala is fueled by the licit import of handguns. Once weapons have entered Guatemala, illicit actors have greater opportunity to divert these firearms from their intended use and users, instead wielding them to pursue crime and perpetrate violence.

This report uses seizure data and supply chain analysis to assess how the international flow of weapons into Guatemala is vulnerable to diversion, or the rerouting of licitly transferred conventional arms from their intended recipient or use.

This analysis reveals:

Handguns are the predominant weapon type used in violent crime in Guatemala. Many of the seized handguns are produced by major international weapons manufacturers such as Glock, Israeli Weapons Industries (IWI), Taurus, and Beretta.

Diversion pathways in-country appear among private citizens, commercial, andgovernment actors, presenting opportunities for illicit actors to acquire licit firearms.

Handguns, predominantly those made by top manufacturers, continue to flow into Guatemala.

These weapons are most often manufactured in the U.S., Brazil, and Turkey.

Manufacturers or entities within the manufacturer’s corporate network account for most handgun exports to Guatemala.

Handguns entering Guatemala primarily do so via air. They often transit through third countries and/or third parties, complicating due diligence and creating greater opportunity for diversion.

The U.S., Canada, and Germany are the most common transit countries for Guatemalan handgun imports.

U.S. gun stores are the most common non-manufacturer exporters of handguns to Guatemala.

The majority of Guatemalan importers are not end-users, but retailers that sell to both government and civilian consumers.

This report uses cases of weapons seizure and diversion to explore each of these findings. Using new data, we re-examine a case of Israeli arms that were sold in Guatemala in exchange for weapons later diverted to paramilitary forces in Colombia.

These findings illuminate areas where Guatemalan and international stakeholders can do more to counter the diversion of firearms in Guatemala. To this end, the report makes targeted recommendations for closing gaps in current legislation and enforcement.

This study uses a combination of tract-level and street network-level analyses to exam-ine: (1) the overall association between federally licensed firearm dealers (FFLs) and homicides, (2) the relation-ship between dealers with serious violations (such as selling to prohibited buyers or failing to record sales)and homicide, and (3) whether the dealer–homicideassociation is moderated by community disadvantage.Results replicate and confirm a relationship between dealers and homicides in disadvantaged neighborhoods.Importantly, however, we also find that proximity to non compliant dealers specifically elevates the risk of lethal violence.Policy implications: We detail how a coordinated effort between federal, state, and local agencies to reg-ulate firearm dealers and ensure that legal compliance can be instrumental in reducing gun violence. There Is a clear need for increased oversight of gun dealers and more robust policies that hold negligent dealers accountable, including the necessary funding and regu-latory manpower to enable regular auditing and support consistent follow-up for noncompliant dealers. A com-prehensive policy framework that supports supply-side gun violence reduction should include additions to state-level laws that require record keeping, videotap-ing and store security, and regular inspection for firearm dealers.

Background

Following the 2018 mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, there was a dramatic increase in media coverage of extreme risk protection orders (ERPOs) and in state policy proposals for ERPO laws. This study documents the frequency of news coverage of ERPOs throughout 2018 and examines the narratives used by media outlets to describe this risk-based firearm policy.

Methods

Using a mixed-method descriptive design, we examine the frequency of national news media coverage of ERPO legislation in 2018, before and after the Parkland shooting, and analyze the content of news articles related to a sample of states that considered ERPO legislation after the shooting.

Results

We find a sharp increase in the frequency of articles related to ERPOs following the Parkland shooting and smaller increases in coverage surrounding ERPO policy proposals and other public mass shootings that year. Nearly three-quarters of articles in our content analysis mentioned the Parkland shooting. The news media often mentioned or quoted politicians compared to other stakeholders, infrequently specified uses for ERPOs (e.g., prevention of mass violence, suicide, or other violence), and rarely included evidence on effectiveness of such policies. More than one-quarter of articles mentioned a mass shooting perpetrator by name, and one-third of articles used the term “gun control.”

Conclusions

This study describes the emerging public discourse, as informed by media messaging and framing, on ERPOs as states continue to debate and implement these risk-based firearm violence prevention policies.

Developing interventions to prevent firearm-related violence and to address its consequences requires an improved understanding of when these violent events are most likely to occur. We explored gunshot events in 6 of the most populated cities in the United States by time of day, day of week, holiday/ non-holiday, and month using publicly available datasets. In some of these cities, gunshot events occurred most often at nighttime, on holidays and weekends, and during summer months, with significant interaction effects. There were also time-related changes in characteristics of the victims. Primary prevention efforts aimed at curbing firearm-related violence should consider these differential risks.

This study examines the reality and news media coverage of all mass shootings in the United States from 1966 to 2016. It employs agenda-setting and framing theoretical frameworks to determine the social construction of mass shootings via the mass media. The project uses open-source data to create a comprehensive list of mass shooting incidents. It then identifies all published New York Times articles on each incident. The study summarizes both the reality of the social problem (i.e. incidents) and the news mediated reality (i.e. New York Times). Next, this dissertation conducts a media distortion analysis to determine the perpetrator, motivation, and incident characteristics influencing media selection, prominence, and framing. The purpose is to illustrate the media’s social construction of mass shootings that in turn shapes public perceptions, political discourse, and public policies. The study concludes by highlighting the findings and implications for scholars, practitioners, policy-makers, media outlets, and the general public.

Gun violence is an urgent, but often overlooked, issue in Latino1 communities. With hundreds of Latinos shot and killed every year2, it is important to understand the unique forces that drive violence in Latino communities. This brief provides a descriptive overview of Latino gun violence victimization in Chicago. While most analysis in this brief is done at the city scale, we acknowledge that Latino communities in Chicago are diverse and that community violence intervention organizations who work in these communities employ different approaches that are responsive to their hyper-local context. We examine definitions, demographics, and gun violence networks before concluding with a summary of a convening of practitioners, leaders, and researchers in December 2022.

In many communities across the country, gun violence has been an unrelenting drumbeat. In a single deadly day, gun violence claimed the lives of a 31-year-old father in Port Allen, Louisiana; a 43-year-old in Philadelphia, Pennsylvania, who was known as a stylish dresser with a great sense of humor; an 11-year-old in Columbia, Missouri, who loved to dance and play with her cousins; and a 17-year-old in Columbus, Ohio, who was a gifted boxer.

Each day, hundreds of lives like these are lost or irrevocably changed as this crisis rages on.

But in the last two years, the tempo of this beat has gotten faster. Gun violence has skyrocketed in cities and towns across the country, leaving more devastation and more trauma in its wake.

More than 45,000 Americans were killed in acts of gun violence in 2020—a 15% increase over the previous year. This increase was primarily driven by an unprecedented 35% rise in gun homicides. In fact, more people were lost to gun violence in 2020 than any other year on record, and although final data is not yet available, the gun death total in 2021 is likely to surpass these records.

This drumbeat is ever-present, but one to which too many have become numb. For too long, this epidemic has gone unchecked, and even as it has spiraled out of control, too many leaders are choosing to do nothing. This moment demands attention, and we must do more to mitigate these increases and protect communities in crisis.

This report provides data describing how gun violence has skyrocketed in 2020 and 2021, showing that this historic rise in gun violence has primarily served to intensify this crisis in communities that already suffered the greatest burden. Additionally, this report describes and considers the factors that most likely contributed to these increases, based on available evidence, and makes suggestions for how policymakers can best respond to this unprecedented challenge.

Introduction: Past research has demonstrated a “reopening phenomenon” of increased firearm violence associated with the initial lifting of coronavirus disease 2019 (COVID-19) pandemic-related restrictions after the first wave. Now, with widespread societal reemergence from stay-at-home measures, we hypothesize another spike in firearm violence in the United States (US). Thus, the purpose of this study was to evaluate the trends in firearm violence before and after extensive community reopenings during the COVID-19 pandemic. Methods: The Gun Violence Archive was utilized to collect data on daily firearm violence incidents, injuries, and deaths as well as on types of firearm violence. ManneWhitney U-tests were performed for trends and types of firearm violence “before” (12/14/20-4/9/ 21) versus “after” (4/10/21-7/31/21) widespread societal reopening in the US. Additional analyses also sought to compare the after reopening time-period to historical data (2017- 2020) of similar calendar dates, to better control for possible annual/seasonal variation. Results: Median daily firearm violence incidents (153 versus 176, P < 0.001), injuries (89 versus 121, P < 0.001) and deaths (54 versus 58, P < 0.001) increased from before versus after reopening. Compared to all historical years, in the after reopening time-period there were consistent increases in total as well as mass shooting incidents/injuries/deaths (all P < 0.05). Conclusions: Firearm violence incidents, injuries, and deaths increased after societal reemergence from the COVID-19 pandemic. In addition, there has been an increase in mass shootings despite a relative lull initially brought on by the pandemic. This suggests the “reopening phenomenon” has worsened an already substantial national firearm epidemic

We present the rationale behind four types of laws that restrict access to firearms for those who are deemed to be a high risk for future gun violence and two types of laws that implement firearm purchase prohibitions. We also present evidence on the effectiveness of these laws. Broadly, these are laws that restrict access for domestic violence abusers, individuals convicted of misdemeanor violence, and individuals at high risk of violence against themselves or others. We briefly discuss relinquishment of firearms by those who are newly restricted, but we focus mainly on how purchase restrictions are implemented by the federal government and across states. Extant research shows that well-implemented firearm policy that is based on evidence-based risk factors can be effective in reducing firearm injury

A wide variety of electric shock devices are specifically designed for and marketed to law enforcement. These range from electric shock stun guns, batons and shields, and body-worn electric shock devices which deliver electric shocks through direct contact with the body; to projectile electric shock weapons (PESWs) which can be fired from a distance. Despite the clear human rights risks associated with this equipment, there are no global regulations controlling what type of electric shock law enforcement equipment is permitted to be manufactured and used, or where equipment which can have a legitimate role in law enforcement can be traded. There is an urgent need for legally-binding, global regulations – a Torture-Free Trade Treaty - which prohibits the production of and trade in inherently cruel, inhuman and degrading devices, such as direct contact electric shock equipment, and strictly controls the trade in PESWs to law enforcement agencies to ensure

  Summary Armed groups’ involvement in illegal mining in Nigeria has exacerbated arms smuggling, consequently increasing insecurity and violent conflict in the country and across the Sahel. It’s also seen a rise in the kidnapping of women and girls for forced labour in the mines. Governments must deal with the socio-economic and political factors that sustain banditry in Nigeria’s North West Region, the involvement of armed groups in illegal mining and the transnational dimensions of the crime. Key points • Armed groups engage in illegal mining due to corruption by state actors and community members, as well as poverty and a lack of opportunities. • Inconsistencies in Nigeria’s mining sector regulations, specifically between the Nigerian Minerals and Mining Act, 2007, and the Land Use Act, 2004, exacerbate the problem. • Armed groups’ control of mining areas undermines government legitimacy and stability. • Militarisation has been unproductive and security forces are compromised by corruption. • Illegal mining fuels security problems and the proliferation of small arms and light weapons. • The transnational criminal market for illegally mined gold extends to Chad, India, Lebanon, Niger and the United Arab Emirates. • The use of girls in mining violates international labour laws.

Understanding the motivation of a mass shooter’s intent to do harm can help practitioners and policy makers develop more effective intervention strategies. OBJECTIVE To examine the prevalence of communication of intent to do harm, known as leakage, in a sample of 170 mass public shooters from 1966 to 2019; the characteristics of perpetrators who do and do not leak their plans; and whether leakage is a form of fame-seeking behavior or a cry for help among individuals who are in crisis or suicidal. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study included perpetrators who killed 4 or more people in a public space from 1996 to 2019 and were included in a comprehensive database of US mass shootings. That database was built from August 2017 to December 2019, and analysis took place from January to May 2021. MAIN OUTCOMES AND MEASURES Leakage was identified and coded using publicly available records. Any communication to a third party of an intent to do harm prior to the shooting was coded as leakage. Logistic regression models were used to examine the risk factors associated with leakage. Models estimating leakage were examined to assess the 2 hypothesized pathways to leakage (the cry-for-help model and the fame-seeking model). RESULTS The 170 participants in this sample included 166 (97.7%) male perpetrators and 3 (2.3%) female perpetrators, with a mean (SD) age of 34 (12) years. Overall, 161 participants had known race and ethnicity: 11 (6.8%) Asian individuals, 35 (21.7%) Black individuals, 14 (8.7%) Latinx individuals, 7 (4.4%) Middle Eastern individuals, 3 (1.9%) Native American individuals, 89 (55.3%) White individuals, and 2 (1.2%) individuals with other race and ethnicity. Overall, 79 mass shooters (46.5%) leaked their plans. Of perpetrators who leaked their plans, 35 (44.3%) leaked specific plans about a mass shooting, and 44 (55.1%) leaked nonspecific plans about generalized violence. The study findings indicate that leakage was associated with receiving counseling (odds ratio, 7.0; 95% CI, 2.0-24.8) and suicidality (odds ratio, 3.7; 95% CI, 1.0-13.6), suggesting that leakage may best be characterized as a cry for help from perpetrators prior to their act.

  Mass shootings (MS) account for less than 1% of firearm deaths in the US, but the frequency has increased.1 Risk factors for MS perpetration include societal discrimination, contagion effects, firearm access, mental illness, and substance abuse.2 Previous geographically and analytically limited studies found MS with handguns had higher fatality rates than those with rifles,3 and following an age-based assault weapons (AWs) restriction there was a reduction in firearm violence from AWs.4 Another study found that the 1994 federal AWs ban was associated with fewer MS.5 To further investigate the association between type of firearm and lethality of MS, this study examined what firearms were present at publicly targeted fatal MS and determined if AWs were associated with a higher number of injuries or deaths.

I demonstrate the linkage between gentrification and gun violence. As the underlying mechanism, I focus on gentrification's displacement effect on local drug markets. Using two-way fixed effects differences-in-differences estimators, I show the gentrification of one block increases violence across the surrounding neighborhood. I find that some 2,400 (8%) of Philadelphia's shootings between the years 2011 and 2020 can be attributed to spillover effects from the gentrification of drug blocks. This effect is nearly ten times stronger than that observed on blocks without high levels of drug crime. This study also contributes a new empirical measurement of gentrification drawn primarily from property sales, along with building, zoning, and alteration permit issuance and utilizes a novel nearest-neighbor network approach to identify spatial spillover effects.

  Firearm purchaser licensing (FPL) laws (sometimes referred to as permit-to-purchase) require an individual to obtain a license through an application process before purchasing a firearm. They are among the most effective policies at reducing gun violence. FPL laws create robust mechanisms of accountability among both prospective gun owners and sellers to ensure that those disqualified from firearm ownership can’t legally obtain a gun. This report compiles existing research to inform state policy. It includes an overview of state FPL laws and recommends core components of FPL laws to maximize public health benefits.

The authors recommend that state gun licensing laws include five core components to maximize public health benefits:

• Firearms safety training

• Fingerprinting

• In-person application

• Comprehensive background checks

• Waiting periods between application and possession of a firearm

Currently 11 states—Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, Michigan, Nebraska, New Jersey, New York, and Oregon—and Washington, D.C., have active firearm purchasing licensing laws. Of these, five states—Delaware, Hawaii, Massachusetts, New Jersey, Oregon—and Washington, D.C., have the five components recommended in the report.

“There is solid evidence from public health research suggesting that when states adopt firearm purchaser licensing laws with measures such as mandatory safety training, comprehensive background checks, and waiting periods, reductions in gun-related homicides and suicides follow,” says study lead author Silvia Villarreal, MPP, director of research translation at the Johns Hopkins Center for Gun Violence Solutions.

Gun violence is a significant cause of mortality for Americans, and the leading cause of death for children and young people ages 1 to 17. According to the Centers for Disease Control and Prevention, 46,728 people died from gunshots in the U.S. in 2023, the most recent year for which final statistics are available. The 2023 CDC data shows firearms were used in seven out of 10 homicides and 55% of suicides.

U.S. federal law requires background checks for would-be gun buyers at federally licensed gun stores but does not cover private sales or gun shows. Moreover, federal law generally allows a gun sale to proceed if the background check is still pending after three business days. 

The report cites evidence—in many cases generated by the report’s co-authors—that firearm purchaser licensing reduces gun violence. A 2018 study linked gun purchaser licensing laws to an 11% reduction in gun homicides in urban counties across the U.S. from 1984 to 2015. A 2020 study found that gun purchaser licensing laws were associated with 56% fewer mass shooting incidents and 67% fewer mass shooting victims on average. Another 2020 study linked Connecticut’s 1995 handgun purchaser licensing law to a 28% drop in the state’s gun homicide rate and a 33% drop in its gun suicide rate from 1996 to 2017.

Similarly, a 2014 study found that Missouri’s 2007 repeal of its handgun-buyer licensing law was followed by 25% increase in its gun homicide rate in the five years following enactment. A 2015 study found a 16% increase in Missouri’s gun suicide rate in the five years following the repeal.

“This report is an important resource that brings together the research, policy, and legal considerations about firearm purchasing laws,” says Josh Horwitz, JD, co-director of the Center for Gun Violence Solutions. “Our intent is to give policymakers and advocates all the guidance and evidence they need to bring these policies to fruition.” 

The researchers hope that the report will encourage state policymakers to maintain or strengthen existing firearm-purchaser licensing laws and enact firearm purchasing laws in states that don’t yet have them.

  BACKGROUND: Firearm violence remains a leading cause of death and injury in the United States. Prior research supports that alcohol exposures, including individual-level alcohol use and alcohol control policies, are modifiable risk factors for firearm violence, yet additional research is needed to support prevention efforts. OBJECTIVES: This scoping review aims to update a prior 2016 systematic review on the links between alcohol exposure and firearm violence to examine whether current studies indicate causal links between alcohol use, alcohol interventions, and firearm violence-related outcomes. ELIGIBILITY CRITERIA: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines, a comprehensive search of published studies was conducted, replicating the search strategy of the prior review but focusing on studies published since 2015. The review included published studies of humans, conducted in general populations of any age, gender, or racial/ethnic group, that examined the relationship between an alcohol-related exposure and an outcome involving firearm violence or risks for firearm violence. Excluded were small studies restricted to special populations, forensic or other technical studies, non-original research articles such as reviews, and studies that relied solely on descriptive statistics or did not adjust for confounders. SOURCES OF EVIDENCE: The review included published studies indexed in PubMed, Web of Science, and Scopus. Eligible articles were published on or after January 1, 2015. The latest search was conducted on December 15, 2023. CHARTING METHODS: Using a structured data collection instrument, data were extracted on the characteristics of each study, including the dimension of alcohol exposure, the dimension of firearm violence, study population, study design, statistical analysis, source of funding, main findings, and whether effect measure modification was assessed and, if so, along what dimensions. Two authors independently conducted title/abstract screening, full-text screening, and data extraction until achieving 95% agreement, with discrepancies resolved through discussion. RESULTS: The search yielded 797 studies. Of these, 754 were excluded and 43 met the final inclusion criteria. Studies addressed a range of alcohol exposures and firearm violence-related outcomes, primarily with crosssectional study designs; 40% considered effect measure modification by any population characteristic. Findings from the 21 studies examining the relationship of individual-level alcohol use or alcohol use disorder (AUD) with firearm ownership, access, unsafe storage, or carrying indicated a strong and consistent positive association. Seven studies examined associations of individual-level alcohol use or AUD with firearm injury or death; these also indicated a pattern of positive associations, but the magnitude and precision of the estimates varied. Eight studies examined the impact of neighborhood proximity or density of alcohol outlets and found mixed results that were context- and study design-dependent. Two studies linked prior alcohol-related offenses to increased risk of firearm suicide and perpetration of violent firearm crimes among a large cohort of people who purchased handguns, and two studies linked policies prohibiting firearm access among individuals with a history of alcohol-related offenses to reductions in firearm homicide and suicide. Finally, four studies examined alcohol control policies and found that greater restrictiveness was generally associated with reductions in firearm homicide or firearm suicide. CONCLUSIONS: Findings from this scoping review continue to support a causal relationship between alcohol exposures and firearm violence that extends beyond acute alcohol use to include AUD and alcohol-related policies. Policies controlling the availability of alcohol and prohibiting firearm access among individuals with alcohol-related offense histories show promise for the prevention of firearm violence. Additional research examining differential impacts by population subgroup, alcohol use among perpetrators of firearm violence, policies restricting alcohol outlet density, and randomized or quasi-experimental study designs with longitudinal follow-up would further support inferences to inform prevention efforts.

This policy brief examines the methods of firearms acquisition by right-wing extremists (RWEs) in Europe between 2019 and 2024. Based on a dataset of 118 cases, it reveals that RWEs resort to diverse legal and illegal acquisition strategies, including the use of illicit markets, legal possession, theft from military and law enforcement sources, and private manufacture, particularly 3D printing. The policy brief further discusses current EU countermeasures and their effectiveness in addressing RWE-specific acquisition methods. It identifies gaps in existing policies and enforcement, particularly regarding background checks in issuing and reviewing weapon licences, screening of military and law enforcement personnel, and regulation of emerging technologies like 3D printing. The authors call for further research to increase the understanding of the RWE-firearms nexus and to develop more targeted prevention strategies.
