Precarious firearm conduct among inexperienced gun possessors has the potential to intensify firearm-related fatalities and injuries. The current study involves face-to-face interviews with 51 high-risk (and prohibited) residents of Brooklyn and the Bronx, NY, each of whom have either been shot or shot at. We analyze study participants’ lived experiences regarding urban gun violence (including as victims and perpetrators), firearm handling, sharing, and improper storage. Despite claiming to be knowledgeable about firearm fundamentals, the vast majority of respondents acknowledged never having received professional instruction, but rather “figured it out” by “playing around” with available guns. These informal methods were shaped by respondents’ desire to arm themselves despite inadequate access to firearm training. Study participants also described routinely stashing firearms in unsecure, easily accessible locations. Our study findings have important implications for informing community-based harm reduction and safety strategies among persons within high-risk networks.

New York City (NYC) has experienced large reductions in violent crime over the last two decades, but gun-related violence continues to pose a threat to public safety. Despite strong gun laws, high-risk individuals in NYC neighborhoods are unfortunately still able to access and misuse firearms. This research analyzes NYC's underground gun market by closely examining the flow of guns into the two boroughs where gun violence and crime gun recoveries are most prevalent: the Bronx and Brooklyn. A mixed methods approach is utilized that consists of an assessment of firearms trace data and in-depth interviews with individuals considered to be at high risk for involvement in gun violence. Findings suggest that guns recovered in the Bronx and Brooklyn were significantly more likely to originate in states with less restrictive gun laws and more likely to have changed ownership in unregulated transactions relative to guns recovered elsewhere in NYC. Interviews revealed three primary avenues for illegal guns reaching Bronx and Brooklyn neighborhoods: high-volume gun brokers, middlemen, and individuals who make episodic low-level acquisitions from straw purchasers in other states. No subjects identified theft as a meaningful source of crime guns.

This paper estimates consumer demand for firearms with the aim of predicting the likely impacts of firearm regulations on the number and types of guns in circulation. We first conduct a stated-choice-based conjoint analysis and estimate an individual-level demand model for firearms. We validate our estimates using aggregate moments from observational data. Next, we use our estimates to simulate changes in the number and types of guns in circulation under alternative regulations. Importantly, we find that bans or restrictions that specifically target “assault weapons” increase demand for handguns, which are associated with the vast majority of firearm-related violence. We provide distributions of consumer surplus under counterfactuals and discuss how those distributions could be useful for crafting policy.

Among researchers, policymakers, and advocates, momentum is growing to better understand the impact of firearm laws on a variety of outcomes (e.g., suicide, crime, defensive gun use, homicide). There is also a growing interest in data that can shed light on these relationships. One source of these data is the National Instant Criminal Background Check System (NICS). This system includes information used in background checks, the number and type of background checks processed, and details on the number of and reason for denials when NICS finds that an individual is prohibited from purchasing a firearm. In this tool, researchers provide detailed information about data associated with NICS and discuss the data's strengths and weaknesses for various gun policy evaluation objectives. The researchers also outline the substantial limitations to interpreting these data to assist researchers in this field. Finally, they provide these data to researchers to encourage further exploration and evaluation of how NICS data might be used for policy analysis.

  Do firearm purchase delay laws reduce aggregate homicide levels? Using variation from a 6-month countrywide gun demand shock in 2012/2013, we show that U.S. states with legislation preventing immediate handgun purchases experienced smaller increases in handgun sales. Our findings indicate that this is likely driven by comparatively lower purchases among impulsive consumers. We then demonstrate that states with purchase delays also witnessed comparatively 2% lower homicide rates during the same period. Further evidence shows that lower handgun sales coincided primarily with fewer impulsive assaults and points towards reduced acts of domestic violence.

Gun violence is a major problem in the United States, and extensive prior work has shown that higher temperatures increase violent behavior. In this paper, we consider whether restricting the concealed carry of firearms mitigates or exacerbates the effect of temperature on violence. We use two identification strategies that exploit daily variation in temperature and variation in gun control policies between and within states. Our findings suggest that more prohibitive concealed carry laws attenuate the temperature–homicide relationship. Additional results suggest that restrictions primarily decrease the lethality of temperature–driven violent crimes, rather than their overall occurrence, but may be less effective at reducing access to guns in more urban areas.

This article argues that the status quo is unacceptable, and proposes a clear, workable solution. Congress should empower the Commission to regulate the safety of guns as products, without granting the Commission authority over "gun control" as traditionally understood. This approach resolves the inadequacies of industry self-regulation, tort, and state consumer law; appropriately leverages the existing Consumer Product Safety Act framework; and is consistent with the Commission’s longstanding oversight of holsters, gun locks, and gun safes. Under this approach, the firearms industry would be obligated to report safety defects, recall dangerously defective firearms, and offer remedies to consumers. The Commission could also consider adopting common-sense product safety standards (such as regulations to ensure that new firearms have functional safety devices, and do not discharge without a trigger pull), just as the Commission adopts safety standards for many other consumer products. But the Commission would be precluded from regulating guns to curtail gun violence or suicide, or to reduce guns’ prevalence.

This approach is fully compatible with the Second Amendment in light of New York State Rifle and Pistol Association v. Bruen (2022). And lifting the firearms industry’s immunity from product safety law—thereby regulating guns as products—has helpful implications for broader debates on gun law and policy. By establishing that Commission regulation could simultaneously protect the public from harm and facilitate the right to lawful self-defense, this Article’s proposal demonstrates that some gun regulations can concurrently respect gun rights, uphold consumers’ rights, and protect lives—and, in doing so, reveals fissures between the interests of the gun industry and gun owners.

Detailed, comparative research on firearm violence in Europe is rare. Using data from the European Homicide Monitor, this paper presents the prevalence and characteristics of firearm homicides in Denmark, Finland, the Netherlands, Sweden and Switzerland between 2001 and 2016. Furthermore, we compare firearm to non-firearm homicides to assess the degree of uniqueness of firearms as modus operandi. We find that the firearm homicide rate varies across our sample of countries. We also identify two country profiles: in Denmark, the Netherlands and Sweden, most firearm homicides take place in public and urban areas, involving male victims and perpetrators. In these countries, the use of firearms in homicides is largely concentrated in the criminal milieu. In Finland and Switzerland, firearms are mostly used in domestic homicides, with a higher share of female victims. We explore these findings in relation to firearm availability in each country.

Mass shootings are one example of a focusing event that has particular significance for firearms legislation. Mass shootings shock, disturb and provoke enormous and controversial debate, often causing significant public and media resonance, becoming the subject of intense discussion politically. At times providing an impetus for legislative amendments, often in distinct ways that routine gun violence does not. If certain events highlight the need for reform, policy change becomes more likely. Cases with the lowest number of victims are likely to generate the least amount of attention and are most likely to be missed in data collection, rendering them the least noteworthy, least important in terms of lethality and social and political consequence. Various problems come to the attention of people in and around government, necessitating an understanding of why such problems occupy officials’ attention and appear to be more ‘deserving’ of attention.

In an average year, gun violence in America kills 40,000 people, wounds twice as many, and has an economic consequence to our nation of $557 billion. Without a doubt, the human cost of gun violence—the people who are taken from us and the survivors whose lives are forever altered—is the most devastating. In addition to this human impact, examining the serious economic consequences of gun violence offers a wider lens for understanding just how extensive and expensive this crisis is. …This $557 billion problem represents the lifetime costs associated with gun violence, including three types of costs: immediate costs starting at the scene of a shooting, such as police investigations and medical treatment; subsequent costs, such as treatment, long-term physical and mental health care, earnings lost to disability or death, and criminal justice costs; and cost estimates of quality of life lost over a victim’s life span for pain and suffering of victims and their families. As survivors, families, communities, employers, and taxpayers, we all pay for the enormous costs associated with this violence, whether we own a gun or not. The daily toll is staggering….The large variation in rates of gun deaths and injuries in the 50 states and Washington, DC, translates into substantial differences in the economic burden from this violence.

  The past 40 years have seen nothing short of a revolution in Americans’ right to carry a concealed firearm in public. In 1980, the vast majority of states either did not grant concealed weapon permits or offered them only on a “may-issue” basis, meaning that authorities retained discretion to deny applications. Since then, many states have adopted “shall-issue” laws, under which anyone who meets certain objective requirements—such as passing a background check, paying a fee, and getting some training—is guaranteed a permit. In recent years, more than 20 states have decided not even to require permits, though restrictions based on age, criminal history, etc., still apply. And earlier this year, in New York State Rifle & Pistol Association Inc. v. Bruen, the Supreme Court ruled that the Constitution protects the right to public carry while striking down New York’s requirement that permit applicants demonstrate a special need to carry, but allowing states to continue to require objective criteria. Now that right-to-carry (RTC) is becoming universal, the purpose of this brief is to ask what the policy’s consequences for crime rates have been thus far. In many ways, it is the perfect “natural experiment.” One by one, most of the states throughout the country decided to make it much easier to carry guns in public; if either side of the gun debate is correct, these policy changes should have led to sizable shifts in crime rates. In theory, measuring such shifts should be easy because during times when some states were changing their laws, others were not— and the latter may serve as a handy control group for the former. With so many experiments running for so many years, the results should be clear by now, both in the raw data and with the aid of modern statistics. That is not how things have played out. Twenty-five years after the first rigorous studies on RTC were published, social science has not resolved the issue…

Analysis from 750 cities of data available for the first times reveals that:

• The rate of people who died by gun suicide in cities increased 11 percent over the past decade, and now make up an average of over four in 10 city gun deaths.

• Cities in states with the strongest gun violence prevention laws have about half the rate of people who die by gun suicide as those in states with the weakest laws, demonstrating the importance of legislative action in preventing gun violence in cities.

• Cities with the most gun shops experience nearly four times higher rates of people who die by gun suicide than those with the fewest gun shops, signaling the importance of expanding cities’ focus beyond illegal guns.

• Smaller cities and those with fewer walkable neighborhoods (i.e., distance to local resources) experience higher rates of people who die by gun suicide, underscoring the importance of adequate access to resources and networks of social support that reduce risk factors like social isolation.

• Cities with the most parks have about half the rate of people who die by gun suicide as those with the least, suggesting that cleaning and greening efforts may offer benefits in reducing both gun homicides and suicides.

Every January, thousands of firearm, ammunition, and accessory manufacturers and importers gather in Las Vegas to show off their new products at the largest trade show of its kind. The Shooting, Hunting, Outdoor Trade (SHOT) Show is the gun industry’s biggest event of the year, garnering some 55,000 attendees in 2020, before the pandemic, and currently boasting more than 2,400 exhibitors.1 But unlike other gun shows, the SHOT Show is a closed-door event open only to exhibitors, potential customers who buy in bulk — including gun wholesalers, retailers, and military and law enforcement personnel — and media outlets that regularly cover firearms.

The first event associated with the annual SHOT Show falls on Martin Luther King Jr. Day, when attendees are shuttled 30 miles into the desert to shoot hundreds of new guns from various manufacturers at a massive outdoor shooting range in Boulder City, Nevada.2 The official convention then takes place indoors, at the Venetian Expo Center and Caesars Forum in Las Vegas, where attendees can walk “13.9 miles of aisles”3 over four days to inspect all the new guns, ammo, and related gear on display — after getting through security....

  Even before the handgun ban introduced in 1998 following the school shooting at Dunblane, Scotland, the UK had one of the world’s stricter firearms control regimes. Partly as a consequence, rates of firearm ownership in England, Wales and Scotland were low, even by European standards. More recently, however, with increasing concerns about gang involved violence, mass shootings, organised crime and terrorism; questions of firearms control have taken on a new significance. In Europe generally, firearm ownership has been creeping upwards and, even as police and security agencies have developed new methods to disrupt firearm trafficking, criminal entrepreneurs find new ways to transport illegal firearms. The trafficking of weapons has been addressed at the European level but issues arising from distinct and separate national ‘gun cultures’ and legal systems, wavering political will, varying ballistic analysis capabilities and differing levels of enthusiasm for intelligence sharing have meant that firearms control across Europe resembles a patchwork with numerous loopholes. Although the introduction of NABIS (the National Ballistics Intelligence Service) in Britain represents an important step forward in ballistics analysis, weapons tracing and intelligence sharing, its ability to withstand the rising global tide of firearms remains to be seen.

This article reviews research undertaken over the past two decades to support international policy on small arms and light weapons (SALW) – which include firearms – and discusses its relevance to academic debates and policy on gun violence. It examines whether SALW research generated a greater understanding of the most problematic uses and users of firearms, and of the role of different weapons as instruments of violence. SALW research helped shift international policy from armed conflicts to gun violence occurring in a range of developing and post-conflict settings, and in Europe following the 2015–16 terror attacks. This work underscored the proximate weapons sources that armed groups often utilise, and the importance of flows of certain weapons – such as converted firearms – and ammunition in fuelling violence. Undertaking impact evaluations of novel interventions, monitoring the impact of new technologies, and investigating the relationship between ammuni-tion supply and violence are suggested ways forward.

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."

  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

  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.

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.

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.
