3D-printed firearms, an emerging category of privately made firearms (PMF) produced beyond government control, have become increasingly prevalent due to technological advancements. They are now emerging as a cost-effective and reliable alternative to conventional firearms. Raised to public awareness following the 2013 release of the 3D-printed Liberator, these firearms are now more commonly encountered by police forces. This article analyses various reports involving 3D-printed firearms, reflecting the increasing encounters by law enforcement agencies. It examines 186 cases involving 3D-printed firearms, primarily from North America, Europe, and Oceania, highlighting a significant rise in incidents since 2021. These incidents include seizures, illicit uses, and online sales, with the firearms typically being hybrid models, Parts Kit Completions/Conversions (PKC), or firearm components such as auto sears. The study underscores the use of affordable equipment and materials for production, emphasizing the accessibility and potential risks of these firearms.

Dangerous Devices: Privately Made Firearms in the Caribbean—a new Situation Update by the Small Arms Survey and its partners CARICOM IMPACS, CARPHA, and GA-CDRC at the University of the West Indies—examines the latest trends and developments regarding PMFs, their production and circulation in the Caribbean region, and calls for more in-depth data collection on these types of weapons to help tackle this threat to security and public health. The Situation Update was launched at the side event ‘A Public Health Crisis: Small Arms Trafficking and Violence in the Caribbean,’ held on 18 June 2024 on the margins of the Fourth Review Conference of the UN Programme of Action on Small Arms. KEY FINDINGS • While privately made firearms (PMFs) represent a small proportion of all firearm seizures in the Caribbean region, the threat appears to be growing as police are recovering a range of different types of PMFs. • Significant seizures of partially finished frames and computer numerical control (CNC)-milled receivers used to assemble firearms have been recorded since April 2023. • The first reported seizure of 3D-printed firearms in the region occurred in August 2023. Seizures of 3D-printed firearms and components have taken place in at least three countries since, also leading to the dismantlement of workshops and recovery of 3D printers. • Seizures of so-called ‘conversion devices’ in several countries underscore the particular threat they pose to public health in the region, given that they can be used to convert semi-automatic pistols and rifles to fully automatic weapons, thus increasing the risk of multiple injuries. • Few seized PMFs are identified as such in the publicly available reports examined by the Survey, which suggests that efforts are needed to improve the detection, identification, and monitoring of these weapons. • Death certificates and other public health records currently do not always capture detailed information about the types of firearms used in shootings, including whether they might have been PMFs.

The household firearms possession rate in Ukraine has been stable since the 2022 Russian invasion. At that time, 6 percent of households reported possessing firearms, which is similar to the 5.6 per cent that did so in a more recent survey carried out at the end of 2023. In fact, in the sampled households the aggregate number of firearms kept at home decreased by 15 per cent during the same period. • During this period, crime victimization levels were only slightly above pre-2022 levels; however, when crimes occur, firearms are increasingly more likely to be used. In late 2023, 11 per cent of all victims said they encountered a firearm during the crime incidents they experienced during the previous 12 months, up from 6 per cent a year earlier. Findings from the latest survey reveal that at the end of 2023, nearly four out of ten firearm owning households were unaware of the Unified Register of Weapons (39 per cent), which was launched in June 2023.  About three-quarters (74 per cent) of respondents whose households owned firearms and knew about the register said all their weapons were registered. Among all survey respondents who reported firearms possession at home, however, only 45 per cent indicated that their firearms were registered. • The war is resulting in an increase in the population of soldiers and veterans, who as a whole tend to adopt distinct attitudes towards firearm ownership. For instance, 31 percent of respondents with combat experience (pre- or post-2022) reported a firearm at their home and 18 per cent declared owning a firearm personally— compared with only about 6 and 3 per cent, respectively, for the general population

Background

Globally, Mexico is one of six countries with the highest level of firearm mortality. While previous studies have examined firearm mortality in Mexico before 2015, increases in violence since then highlight the need for an updated analysis. In this study, we examined changes in firearm-related deaths in Mexico from 2015 to 2022 and described these deaths by key demographic groups, incident location, and state of occurrence. Data came from Mexico’s Instituto Nacional de Estadistica y Geografia (INEGI), a federal agency that collects and reports national population data. We used descriptive statistics to analyze rates, proportions, and percentage changes in firearm mortality, and we displayed temporal trends using time plots and special trends using maps.

Results

Firearm deaths increased in Mexico from 2015 to 2018 but slightly decreased from 2018 to 2022. Homicides presented the highest increase and the highest proportion of firearm-related deaths from 2015 to 2022. Victims were primarily males but rates among women increased at a higher proportion (99.5% vs 53.5%). One third of victims were 20–29y but rates among children and adolescents (10–9y) increased at a higher proportion. Most firearm-related deaths occurred in streets or public spaces but the percentage of incidents occurring in households have increased. State-level rates and percentage changes varied significantly. States with higher rates of firearm mortality coincide with those involving conflict among organized criminal organizations.

Conclusion

Firearm mortality in Mexico is a major public health burden. The epidemiology of firearm-related deaths in Mexico varies by intent, demographics, location, and states. To mitigate this challenge, multiple solutions are required.

Introduction

Previous studies have documented increases in firearm mortality in Mexico from 1990 to 2015 (Dare et al. 2019). Reports from nonprofit organizations and news outlets indicate further increases since 2015, (particularly firearm homicides associated with organized crime) (Calderon et al. 2020), but comprehensive characterization of those trends is lacking. Organized criminal groups continue to operate in Mexico and roughly 213 k firearms are trafficked from the US every year (McDougal et al. 2014). In this regard, further increases in firearm mortality would threaten the future economy and health of Mexico (Peters et al. 2020; Aburto et al. 2016), and yet the lack of precise epidemiological information limits the ability to address this growing national problem with evidence-based programs and policies. In this analysis, we document changes in firearm-related deaths in Mexico from 2015 to 2022 and describe these deaths by key demographic groups (e.g., sex, age, and urbanicity), incident location (e.g., households or public spaces) and states where they occurred.

Methods

Data on causes of death were collected from Mexico’s Instituto Nacional de Estadistica y Geografia (INEGI), a national vital statistic database that has previously been used to examine firearm mortality in Mexico (Dare et al. 2019; Instituto Nacional de Estadística y Geografía 2023a). INEGI collects annual mortality data and provides information on year of occurrence (Instituto Nacional de Estadística y Geografía 2023b). We merged datasets from 2015 to 2022. We excluded deaths that occurred/registered before 2015 and those where year of occurrence was unknown (n = 432), as well as deaths that occurred outside of Mexico (n = 2).

In line with previous studies (Degli Esposti et al. 2023; Cunningham et al. 2018), we identified firearm deaths using the International Classification of Disease (ICD-10) codes for firearm homicide (X93–X95 and U01.4), firearm suicide (X72–X74), unintentional firearm deaths (W32–W34), and firearm deaths of undetermined intent (Y22–Y24). Firearm deaths were further disaggregated by sex and age group (< 10y; 10–19y; 20–29y; 30–39; 40–49y; 50–59y; 60–69y; 70y+) and geographic information (urbanicity, incident location, state of occurrence). Urbanicity was defined using INEGI’s predetermined categories of urbanicity (urban and rural). Similarly, incident location was defined using INEGI’s eight predetermined categories of where deaths occurred (household, school or office, sport fields, streets or public spaces, commercial areas, industrial areas, farms/ranches, and other).

We used descriptive statistics to examine pooled 2015–2022 rates, annual rates for 2015 and 2022 separately, as well as percentage changes (in rates) from 2015 to 2022 across categories of intent, sex, age groups, and state of occurrence. To obtain rates, we used population estimates (by year, sex, age group, and state) provided by Mexico’s Consejo Nacional de Población (CONAPO) (Consejo Nacional de Población 2024). We also examined the percentage of firearm related deaths within categories defined by urbanicity, location, intent, and demographics. We displayed these percentages for 2015, 2022, and the total pooled 2015–2022 period.

Results

We examined 188,397 firearm-related deaths in Mexico from 2015 to 2022. Rates of firearm-related deaths increased by 88.2% from 2015 to 2018 and decreased by 16.7% from 2018 to 2022 (Fig. 1). Homicide accounted for 92.2% of firearm deaths (Table 1) during this period and experienced the highest percentage increase (62.7%) from 2015 (10.37 per 100 k) to 2022 (16.87 per 100 k). Rates of undetermined firearm-related deaths and unintentional shootings also increased during this period (Table 1), while firearm suicide decreased by 23.4% (from 0.47 per 100 k in 2015 to 0.36 per 100 k in 2022).

Why GAO Did This Study The U.S. Southwest Border Counternarcotics Strategy: 2020 identified the trafficking of firearms from the U.S. into Mexico as a threat to the safety and security of both countries. The Mexican government has estimated that 200,000 firearms are smuggled from the United States each year. GAO was asked to report on U.S. efforts to counter firearms trafficking to Mexico. This report examines (1) the extent of U.S. agencies’ knowledge about firearms trafficking to Mexico and (2) U.S. agencies’ efforts to disrupt this trafficking and the extent to which they have assessed those efforts. GAO reviewed firearms tracing data, related analysis, and program information for fiscal years 2014 through 2020. GAO also interviewed U.S. and Mexican officials. This is a public version of a sensitive report that GAO issued in December 2020. What GAO Recommends GAO is making eight recommendations, including recommending that ATF and ICE analyze additional information about the trafficking of U.S.-sourced firearms to Mexico and that ATF, ICE, CBP, and State develop performance measures to assess the results of their efforts to disrupt this trafficking. The agencies concurred with GAO’s recommendations.

How does the internet affect the radicalisation of extreme-right lone actor terrorists? In the absence of an established theoretical model, this article identifies six mechanisms seen as particularly relevant for explaining online radicalisation. Having first reviewed a larger set of relevant lone actor terrorists, the study traces the mechanisms in three selected cases where the internet was reportedly used extensively during radicalisation. The findingsshow that the internet primarily facilitated radicalisation through information provision, as well as amplifying group polarisation and legitimising extreme ideology and violence through echoing.In all three cases, radicalisation was also affected considerably byoffline push-factors that through their presence made extreme online messages more impactful. The results challenge the view that offline interaction is necessary for radicalisation to occur but also the view that online influence itself is sufficient

Latest Version Link ---Technology is integral to police departments, automating officer tasks, but inherently changing their time allocation. We investigate this by studying ShotSpotter, a technology that automates gunfire detection. Following a detection, officers are dispatched to the scene, thereby reallocating their time. We leverage this shock to officers’ time allocation using the rollout of ShotSpotter across Chicago police districts to study the effects on 911 call response. We find substantial consequences— officers are dispatched to calls slower (23%), arrive on-scene later (13%), and the probability of arrest is decreased 9%. Consequently, police departments must evaluate their resource capacities prior to implementing technologies.

Over the past decade, large urban counties have implemented ShotSpotter, a gun fire detection technology, across the USA. It uses acoustic listening devices to identify discharged firearms’ locations. We examined the effect of ShotSpotter with a pooled, cross sectional time-series analysis within the 68 large metropolitan counties in the USA from 1999 to 2016. We identified ShotSpotter implementation years through publicly available media. We used a Poisson distribution to model the impact of ShotSpotter on firearm homicides, murder arrests, and weapons arrests. ShotSpotter did not display protective effects for all outcomes. Counties in states with permit-to-purchase firearm laws saw a 15% reduction in firearm homicide incidence rates; counties in states with right-to-carry laws saw a 21% increase in firearm homicide incidence rates. Results suggest that implementing ShotSpotter technology has no significant impact on firearm related homicides or arrest outcomes. Policy solutions may represent a more cost-effective measure to reduce urban firearm violence.

Background: The prevalence and characteristics of handgun purchasers’ criminal charge histories have never been described for a large population of firearm owners, but such information is critical to understanding risk factors for subsequent violence in this population. We sought to characterize legal handgun purchasers in California and compare this group to the state population, to quantify the proportion with a criminal charge history at purchase, and to identify modifiable factors associated with having such a history.

Methods: This cross-sectional study of all 79,927 legal handgun purchasers aged 21–49 years in California in 2001 used log-linear generalized additive models to identify factors associated with having a criminal charge history at purchase. Subjects are from a longitudinal study of incident criminal activity among handgun purchasers.

Results: The majority (91.03%) of purchasers were male; whites were overrepresented and Hispanics were underrepresented relative to their population size. At the time of purchase, 16.68%  had a criminal charge history and 10.71% had a criminal conviction. Among men with such a history, 31.28% had been charged with a violent crime and 16.54% had been charged with a firearm-related crime. The strongest factor associated with having a criminal charge history was redeeming a pawned handgun (prevalence ratio: 1.82; 95% confidence interval: 1.71, 1.93).

Conclusions: Despite California’s stringent firearm purchase laws, more than 1-in-6 handgun purchasers had a criminal charge history at purchase. This proportion may be higher in states with less restrictive firearm purchasing eligibility criteria.

Background: Privately made firearms (PMFs) or “ghost guns” are homemade, unserialized, untraceable firearms that have been increasingly used in violent crime in the United States. Very little is known about the types of PMFs recovered by law enforcement agencies and the crimes associated with these recoveries. This lack of information limits effective violence prevention policies and practices. Comparative analysis of PMF recoveries in specific cities helps clarify whether local PMF patterns and characteristics vary or reflect more general trends. This research advances epidemiological understanding of emergent violent gun injury prevention challenges by identifying variations in recovered PMF types and use in violent, drug, and weapon-related offenses in Los Angeles and San Diego, California.

Methods: Conjunctive analysis of case configurations (CACC) identifies patterns among observations (i.e., case configurations) and calculates their probability associated with a given outcome. CACC was used to identify the most common types of PMFs recovered by the Los Angeles (LAPD) and San Diego (SDPD) police departments. For each department and offense type, case configurations with above-average probabilities of offense involvement were determined. Comparisons across departments were made to identify similarities and differences in PMF characteristics and usage.

Results: PMFs were more likely to be involved in violent and weapon-related offenses in Los Angles but more likely to be involved in drug-related offenses in San Diego. In both cities, the 9 mm Polymer 80 handgun was the dominant PMF. However, 9 mm handguns were most likely to be involved in weapon-related offenses in Los Angeles compared to 0.40 handguns in San Diego. Furthermore, large-caliber handguns tended to display above-average probabilities of involvement in violent and drug offenses in Los Angeles. Long guns were represented in case configurations with above-average probabilities of involvement in substantive crimes, including violence.

Conclusions: Comparative analyses of PMF recovery patterns in Los Angeles and San Diego reveal meaningful contextual variations in PMF characteristics and suggest intentional firearm type selections by offenders. The results support increased regulation of PMFs and highlight the importance of efforts to identify and disrupt the illicit supply of large-caliber PMF handguns and PMF long guns.

Background: No previous study has identified the specific brands of guns owned by gun owners. This study aimed to (1) ascertain and describe patterns of brand- and model-specific gun ownership among US gun owners; and (2) investigate the relationship between gun owners’ brand and model preferences and their attitudes towards common firearm violence prevention policies.

Methods: Using a national, pre-recruited internet panel of US adults in 2019, we surveyed gun owners (N = 2086) to ascertain their opinions regarding firearm violence prevention policies and to assess the brands and models of guns that they owned.

Results: Brand-specific gun ownership was highly concentrated and was dominated by three pistol brands, two revolver brands, three rifle brands, and three shotgun brands. There was wide variation in policy attitudes among owners of different gun brands, but little variation among owners of different gun types (i.e., pistols, rifles, revolvers, shotguns). We were able to identify the specific gun models owned by 1218 (59.4%) of the gun owners. Based on the classification of these gun models into three types we categorized the gun ownership pattern of the sample as 33.4% recreational, 45.5% self-defense, and 21.1% tactical. There were marked differences in support for firearm-related policies among the three groups, with support generally highest among the Recreation group and lowest among the Tactical group.

Conclusion: We conclude that gun brands and models are strong predictors of a gun owner’s attitudes regarding firearm-related policies. This information could help public health practitioners develop segment-specific communications that will appeal to each group to more effectively engage gun owners in firearm violence prevention.

Grounded on an extensive literature review derived from evidence-based studies (e.g., scientific articles, institutional and technical reports, journalistic evidence, academic books, and book chapters), our article develops a qualitative analysis to address the following question: to what extent do the strategic motivations of states and organized crime groups converge/diverge in the context of the current Russo-Ukrainian conflict? This article is divided into three parts. The initial section delves into the interconnections between illicit markets and armed conflicts. Secondly, after acknowledging the background of organized crime in both countries and the emergence of the current Russo-Ukrainian war, it highlights the implications of this conflict on the dynamics of illicit markets. Finally, it analyzes the strategic motivations of states and organized crime within this setting, as well as its points of convergence and divergence. This research potentially explores the frequently wicked ties of (inter)national politics and criminal adaptation during (post-)war times in Eastern Europe and within the international system.

This article explains some of the mechanisms through which corruption by high-level Mexican politicians and other organized crime members is facilitated in the United States through money laundering operations. The analysis is based on information contained in court records related to key money laundering cases, as well as in news articles and reports from law enforcement agencies. These materials highlight the interrelationships among U.S. drug use, cartel activities in Mexico, human rights abuses, Mexican political corruption, and money laundering in the United States. This work demonstrates the pervasive use of legitimate businesses and fronts in the United States as a disguise for criminal activity. Finally, it provides recommendations for a reformation of policies and penalties directed toward U.S. institutions and persons that facilitate money laundering.

In recent decades, the global debate on gun control has been prominent, with many countries adopting more restrictive policies. Brazil followed this trend by implementing stringent measures in 2003; however, the presidency of Jair Bolsonaro in 2019 introduced normative changes aimed at facilitating public access to firearms and ammunition. Throughout his term, the legal firearms market doubled, allowing access to weaponry previously restricted to the general public. The analyzed hypothesis suggests that these normative changes, especially those related to the quantity and authorization of acquisition of previously restricted firearms, altered the types of firearms in circulation, strengthening the interaction between legal and illegal markets. Using data from the mandatory firearms re-registration, a total of 962,782 firearms were analyzed. The assessment of the increase in circulation of these firearms in the illegal market was conducted through the analysis of seizures in the states of Rio de Janeiro and São Paulo, revealing a significant growth in seizures of these types of firearms, possibly correlated with the increase in their circulation. Three police investigations were selected to exemplify how the connection between markets intensified, allowing criminals to obtain firearms in the legal market that were previously only accessible through international trafficking or diversion from state agencies.

Objective: To describe the prevalence of and factors associated with firearm ownership; the types, subtypes, and quantity of firearms owned; and when, where and why firearms were acquired in California.

Methods: A cross-sectional analysis of a state-representative, probability-based, internet survey of California adults was conducted in September-October 2018 (n=2558; completion rate 49%). Household firearm ownership was ascertained for all respondents; personal firearm ownership was ascertained only among respondents who reported living in a home with firearms; and information on the types and quantity of firearms owned and details about recently acquired firearms came from firearm owners only.

Findings: Roughly one in four (25%, 95% CI 22% to 28%) California adults live in a home with a firearm, including 4.2 million adults-14% (95% CI 13% to 16%) of the adult population who personally own a firearm. These owners collectively own an estimated 19.9 million firearms (8.9 million handguns). Approximately half (48%, 95% CI 34% to 61%) of the firearm stock in California is owned by the 10% (95% CI 6% to 14%) of owners who own 10 or more firearms, though more than half (54%, 95% CI 47% to 62%) of owners in the state own only one or two firearms. Most (69%, 95% CI 63% to 75%) owners purchased their last firearm from a firearm retailer, usually a handgun purchased primarily for protection against people.

Conclusion: This study provides the most detailed and up-to-date information available on firearm ownership and acquisition in California. Results can inform firearm violence prevention efforts and public health, safety, and policy development in California and nationally.

Background: Firearms are the most lethal method of suicide and account for approximately half of all suicide deaths nationwide. We describe associations between firearm purchasing characteristics and firearm suicide. Methods: Data on all legal handgun transactions in California from 1996 to 2015 were obtained from the California Department of Justice Dealer’s Record of Sale database. Handgun purchasers were linked to mortality data to identify those who died between 1996 and 2015. To account for variation in timing and duration of observation time, analyses were stratified by birth cohort. The primary analysis focused on those aged 21–25 in 1996. A secondary analysis tested associations among those aged 50–54 in 1996. Using incidence density sampling, purchasers who died by firearm suicide (cases) were each gender-matched to 5 purchasers (controls) who remained at risk at the case’s time of death. We examined the characteristics of purchasers and transactions, focusing on the transaction closest in time to the case’s death. Data were analyzed with conditional logistic regression. Results: There were 390 firearm suicides among the younger cohort and 512 firearm suicides among the older cohort. Across both cohorts, older age at first purchase and the purchase of a revolver were associated with a greater risk of firearm suicide. For example, among the younger cohort, those who purchased a revolver versus a semiautomatic pistol had 1.78 times the risk of firearm suicide (95% CI 1.32, 2.40) in multivariable models. Other associations varied across cohorts, suggesting cohort or age effects in purchasing patterns. Conclusions: Findings add to the evidence on firearm suicide risk and may help inform prevention strategies and future research.

Background: Little is known about the voluntary divestment of firearms among US firearm owners. Here, we aim to estimate the proportion of handgun owners who divest their handguns in the years following their initial acquisition; examine the timing, duration, and dynamics of those divestments; and describe the characteristics of those who divest. Methods: We use data from the Longitudinal Study of Handgun Ownership and Transfer, a cohort of registered voters in California with detailed information on 626,756 adults who became handgun owners during the 12-year study period, 2004–2016. For the current study, persons were followed from the time of their initial handgun acquisition until divestment, loss to follow-up, death, or the end of the study period. We describe the cumulative proportion who divest overall and by personal and area-level characteristics. We also estimate the proportion who reacquired handguns among persons who divested. Results: Overall, 4.5% (95% CI 4.5–4.6) of handgun owners divested within 5 years of their first acquisition, with divestment relatively more common among women and among younger adults. Among those who divested, 36.6% (95% CI 35.8–37.5) reacquired a handgun within 5 years.

Background Firearm homicide and opioid overdoses were already leading causes of death in the U.S. before both problems surged during the COVID-19 pandemic. Firearm violence, overdoses, and COVID-19 have all disproportionately harmed communities that are socially and economically marginalized, but the co-occurrence of these problems in the same communities has received little attention. To describe the co-occurrence of firearm homicides and opioid overdose deaths with COVID-19 mortality we used 2017–2021 medical examiner’s data from Chicago, IL. Deaths were assigned to zip codes based on descendants' residence. We stratified zip codes into quartiles by COVID-19 mortality rate, then compared firearm homicide and fatal opioid overdose rates by COVID-19 quartile. Findings Throughout the study period, firearm homicide and opioid overdose rates were highest in the highest COVID-19 mortality quartile and lowest in the lowest COVID-19 mortality quartile. Increases in firearm homicide and opioid overdose were observed across all COVID-19 mortality quartiles. Conclusions High co-occurrence of these deaths at the community level call for addressing the systemic forces that made them most vulnerable before the pandemic. Such strategies should consider the environments where people reside, not only where fatal injuries occur.

Background: Reducing firearm access during times of risk is a key component of suicide prevention, including the person at risk voluntarily, temporarily storing firearms outside the home. However, this approach relies on the participation of storage providers (ranges/retailers and law enforcement agencies (LEAs)). Our objective was to describe stakeholders' views and experiences surrounding voluntary, temporary out-of-home firearm storage for suicide prevention.

Method: We conducted individual interviews with (1) firearm ranges/retailers; (2) LEAs (in Colorado or Washington State); and (3) state/national organizations involved in policy development or enactment; public health; or firearm rights. Transcripts were analyzed using a team-based mixed inductive-deductive approach.

Results: Across 100 interviews (October-May 2021), potential storage providers were supportive of voluntary storage programs, often reporting a desire to help their customers and community. However, potential storage suppliers cited civil liability, regulatory, and legal concerns associated with storing and/or returning firearms (to people who had previously expressed suicide risk). Stakeholders offered suggested strategies meant to address liability and increase storage accessibility.

Conclusions: Understanding stakeholder views supports the development of acceptable, feasible programs for out-of-home firearm storage during times of suicide risk. Clarification of existing regulations or the creation of new policies is necessary to address potential providers' concerns.
