Trigger warning: The effect of ATF citations on U.S.–Mexico firearms trafficking

Treating gun violence before the 911 Call*1

Drug trafficking violence in Mexico, now reaching epidemic proportions, greatly impacts both the Mexican and United States governments. Despite the escalation of the "War on Drugs, " drug trafficking from Mexico to the United States continues largely unabated, stifling tourism revenue and lawful economic opportunities, and causing violence previously unknown in Mexico. Thus far, the United States' efforts to deal with this drug trafficking and violence include the recent debacle of Operation Fast and Furious. News regarding this Bureau of Alcohol, Tobacco, Firearms and Explosives'(ATF) operation shocked citizens and lawmakers alike, as Fast and Furious allowed firearms to "walk" down to Mexico unimpeded in a futile attempt to identify firearms traffickers in Mexican drug cartels. Ultimately, this operation led to the presence of over two thousand additional firearms in Mexico, contributing to continued violence south of the U.S. border and the possibility of spillover violence back into the United States. An analysis of Operation Fast and Furious and other law enforcement attempts to stop firearms trafficking and drug cartel violence in Mexico demonstrates that the development and tactics of these operations require a more comprehensive approach to the problems facing Mexico and the United States. This Article discusses extraterritoriality, and the effects of U.S. domestic criminal laws on a foreign country, in the context of U.S. domestic firearms trafficking laws. First, this Article lays out the problem: Mexican drug cartels are receiving thousands of weapons from the United States with which to create havoc and wreak violence upon both nations. It then discusses the dynamics of that problem, which include addressing the current legal framework and the NRA lobbying effort against restrictions on firearms. The Article examines the ATF's Project Gunrunner and Operation Fast and Furious and argues that the lack of a simple and strong firearms trafficking statute contributed to ATF's decision to implement Operation Fast and Furious, thereby contributing to large numbers of firearms heading south to Mexico. The Article further argues that without a true comprehensive firearms trafficking statute, the combined efforts of the United States and Mexico to stem the southbound flow of firearms and resulting drug violence will ultimately fail. Besides seeking to contribute to the dialogue on solving a looming and important problem, this Article endeavors to promote discussion about the extraterritorial effects of U.S. domestic criminal laws. Ultimately, it argues that, in certain contexts, the positive extraterritorial effects of such laws should take priority over complaints about their negligible domestic effects.

Restrictive firearm legislation has correlated with decreased overall firearm fatality rates, but not with firearm-related homicide or firearm mortality among Black Americans. We hypothesized that firearm trafficking from states with less restrictive firearm legislation to neighboring states with more restrictive firearm legislation increases firearm homicide rates in those restrictive states. For years 2011-2015, state firearm legislation Brady Campaign to Prevent Gun Violence scorecards were analyzed in relation to firearms traced by the Bureau of Alcohol, Tobacco, and Firearms and Center for Disease Control and Prevention firearm mortality rates. States were ranked by Brady score and arranged by quintile to establish the Standardized Brady Score. The effect of less-restrictive neighboring states on the 10 most-restrictive firearm legislation states was modeled by averaging the 10 most-restrictive states with their bordering states to create a Border Adjustment Score. Firearm fatality rates were calculated for each quintile and Poisson regression models were created for each score and outcome. Model fit was compared using Akaike Information Criterion (AIC). There were 169,396 firearm fatalities including 57,885 firearm homicides. Comparing top and bottom quintile firearm legislation states, 65% vs. 44% of firearms traced by the Bureau of Alcohol, Tobacco, Firearms and Explosives originated in other states respectively. The Border Adjustment Score generated a more linear relationship than the Standardized Brady Score for all firearm fatality categories as firearm legislation scores decreased. The Border Adjustment Score minimized the AIC with respect to the Standardized Brady Score for black (AIC, 4443 vs. 4680) and white firearm homicide rates (3243 vs. 4319), indicating improved model fit after adjustment for neighboring state firearm legislation. Our results suggest that firearm movement across states plays an important role in firearm homicides. Accounting for firearm legislation in both individual and neighboring states may improve our understanding of the relationship between firearm legislation and homicide.

The illicit acquisition of firearms by youth and juveniles

This report describes a feasibility study on realizing interoperability of the National Integrated Ballistic Information Network (NIBIN) with third-party data acquisition systems, focusing on cartridge case data. NIBIN is the only national network in the United States for the acquisition, archiving, and search of ballistic images. NIBIN aids in solving and preventing crimes by identifying connections between crime scenes or between crime scenes and confiscated firearms. NIBIN is managed by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).NIBIN relies on a commercial product: the Integrated Ballistic Identification System (IBIS®). Due to a lack of standards for data exchange and image quality, the ATF cannot integrate third-party imaging systems into NIBIN. Interoperability may promote innovation and competition, while avoiding possible gaps in NIBIN coverage due to local deployment of third-party systems not connected to NIBIN. In theory, interoperability is facilitated by the proliferation of systems that acquire three-dimensional (3D) topography images. Compared to traditional 2D microscope images, 3D images are less affected by differences in sample setup, lighting, and reflectivity. A data exchange specification was developed for systems that are not part of the NIBIN-IBIS ecosystem. Interoperability experiments were conducted at NIST using an IBIS 3.1 system, modified to enable the import/export of images that meet the specification. The testbed was used to evaluate the impact on search performance of differences in instruments and sample setup. The evaluation focused on 9 mm caliber test fires obtained from approximately 90 pistols each from 4 major manufacturing brands. Test fires were measured by four different instruments, including the IBIS BRASSTRAX HD3D system. The project database was seeded by Forensic Technology with IBIS HD3D images from 4,136 cartridge cases with a Glock-type firing pin impression and 23,461 cartridge cases with a circle-type firing pin impression. The observed third-party, intra-instrument, search performance was similar to that for IBIS images. Inter-system performance was up to 17 % lower for top-30 ranking results and up to 21 % for top-5 ranking results. The reduced performance is due to: 1) differences in 3D images, mainly of the firing pin impression, and 2) the importance of 2D (side light) images for IBIS search performance. Current instruments require modifications to replicate IBIS (side) lighting conditions for 2D images. Exploratory experiments with 2D images rendered from 3D images indicate that the 3D images contain information for improving the reduction in search performance when 2D images are omitted. Visible differences in 3D images from different instruments may affect the comparison of high-ranking images during correlation review. Increased accuracy requirements, both for search and 1-1 case work comparisons, are expected to reduce differences in 3D images through improved measurement and calibration methods. Experiments were conducted during August 2017 – November 2020 using an IBIS 3.1 system for cartridge case imaging and search. Results cannot be used to make inferences about bullets and do not address advances in metrology and search of newer IBIS or third-party systems.

In 2009, the Bureau of Alcohol, Tobacco, Firearms and Explosives successfully traced over 145,000 guns recovered at crime scenes in the United States. Of these guns, more than 43,000 were originally sold in a different state from which they were recovered. What factors may explain the interstate movement of these crime guns? This article uses the well‐known gravity model of international trade to estimate interstate flow of crime guns. Empirical results show that, like trade of goods and services between nations, the traced movement of crime guns between states is proportionate to the economic sizes of trading partners and is inversely proportionate to the distance between them. In addition, the presence of gangs in one or both states tends to increase the flow of crime guns. Finally, differences in state gun laws tend to affect trade flows with crime guns flowing from states with “weak” gun laws to states with “strict” gun laws. (JEL K00, K42)

In An Immigrant’s Run-in with the Law: A Forensic Linguistic Analysis, author Kristina Beckman argues convincingly that linguistic analysis can be a powerful tool when immigrants with limited English are accused of crimes. Central to the book is the compelling story of LK, a Chinese immigrant convicted of illegal practices in weapons sales. Although forensic linguistics was not admissible evidence in the trial, Beckman gained access to the transcripts of a ‘sting’ operation, used by undercover agents to prosecute LK, and analyzed them in-depth to demonstrate how much more key information a forensic linguistic analysis would have provided. LK is described as a citizen of the U.S. who immigrated in 1982 from China via Hong Kong. Through connections with his brother, LK became the proprietor of Gong’s Market, a struggling small business in Tucson, Arizona. Among the wares sold in his store were a variety of arms and ammunition, some of which showed up later at crime scenes. After tracing the weapons found at the scenes of certain crimes back to Gong’s Market, the U.S. Bureau of Alcohol, Firearms, and Tobacco decided to investigate LK’s policies in gun sales to determine whether he intentionally sold guns to criminals without the requisite screening. Posing as gun buyers, members of the Bureau and other confidential informants bought guns from Gong’s Market while surreptitiously tape recording the transactions. The transcriptions of these lengthy recordings are included in an appendix to the volume and form the basis for the analysis conducted by Beckman.

Illicit firearms trafficking imposes severe social and economic costs, eroding public safety, distorting markets, and weakening state capacity while affecting vulnerable populations. Despite its profound consequences for global health, trade, and security, the network structure and dynamics of illicit firearms trafficking are one of the most elusive dimensions of transnational organized crime. News reports documenting these events are fragmented across countries, languages, and outlets with different levels of quality and bias. Motivated by the disproportionate impact in Latin America, this study operationalizes the International Classification of Crime for Statistical Purposes (ICCS) to convert multilingual news into structured and auditable indicators through a three-part analytic pipeline using BERT architecture and zero-shot prompts for entity resolution. This analytical approach generated outputs enriched with named entities, geocodes, and timestamps and stored as structured JSON, enabling reproducible analysis. The results of this implementation identified 8,171 firearms trafficking reports published from 2014 through July 2024. The number of firearms-related reports rose sharply over the decade. Incidents increase roughly tenfold, and the geographic footprint expands from about twenty to more than eighty countries, with a one hundred fifty five percent increase from 2022 to 2023. Correlation analysis links firearms trafficking to twelve other ICCS Level 1 categories, including drug trafficking, human trafficking, homicide, terrorism, and environmental crimes. Entity extraction and geocoding show a clear maritime bias; ports are referenced about six times more often than land or air routes. The analysis yielded eighty-five distinct points of entry or exit and forty-one named transnational criminal organizations, though attribution appears in only about forty percent of reports. This is the first automated and multilingual application of ICCS to firearms trafficking using modern language technologies. The outputs enable early warning through signals associated with ICCS categories, cross-border coordination focused on recurrent routes and high-risk ports, and evaluation of interventions. In short, embedding ICCS in a reproducible pipeline transforms fragmented media narratives into comparable evidence for strategic, tactical, and operational environments.

Illicit firearms trafficking is a transnational problem affecting communities worldwide. It enables, and is frequently intertwined with, other organized crime activities, such as drug and human trafficking. Illicit firearms trafficking is considered to be primarily carried out by organized criminal groups. A way to map and measure relationships and flows between individuals in firearms trafficking groups is provided by social network analysis (SNA). This chapter focuses on using SNA to understand the criminal activities in firearms trafficking networks and the social structures facilitating those activities in the European context. By means of a multiplex network approach, six network layers or tie types were examined, including ties that support the flow of commodities (firearms, money, and equipment) and those that facilitate social dynamics (orders, negotiation, and planning). A case study of a Dutch firearms trafficking network that was subject to police investigation was used. The merged network consisted of forty-two actors with 224 ties between them, including ties of which the link type was unknown. SNA metrics (density, degree centralization, average degree, degree centrality, and betweenness centrality) were calculated for the merged network and the six individual network layers. Results are discussed in light of the literature on the social organization of criminal groups. The chapter concludes with implications of results for policy and practice.

This article gives an overview of the thrust and core provisions of the Protocol against the Illicit Manufacturing of and Trafficking in Firearms, Their Parts and Components and Ammunition 20 years after its adoption. It examines the interlinkages between illicit firearms trafficking and other crimes and the ability of the Firearms Protocol to address these threats, as well as its ties to other international instruments in this area and existing challenges and responses in its implementation.

Small Arms and Light Weapons (SALW) trafficking become a great threat to the peace and security of Ethiopia. Throughout the whole year of 2020, in all parts of the country, the seizure of illicit firearm is the agenda of many Medias, security organs, and the people. Thus, this study aims to examine the routes, and consequences of illicit firearms trafficking. It covered purposively selected areas parts of Ethiopia. The study used qualitative research approach and exploratory design. The study samples were 19 inmates detained due to the firearm trafficking, 32 police officers, 9 militias, and 9 community leaders who were selected through purposive sampling technique. Data were collected through interview and FGD, and then thematically analyzed. The finding of the study showed that the major routes of firearm trafficking linked to and followed the course from border areas to the central areas of Ethiopia, specifically from neighbor countries like Sudan, South Sudan, Kenya, and Somalia to Addis Ababa. The traffickers or brokers used central areas like Addis Ababa and its surrounding cities as depository spaces to recirculate illicit SALW to areas where there are high needs in the country. Study also revealed that illicit SALW trafficking leads to increment of armed groups and number of conflicts to broke out. As a result, many people were injured, and loss life and millions were displaced from their homes. It also triggered the impediment of peace and security; psychological impact and threat; socioeconomic obstruct; political instability and fueled the commission of firearms supported crimes like homicide, robbery and kidnapping in the study populations. Therefore, the study recommends that the security sectors should aware and updated of modus operandi used by illicit SALW traffickers through continues trainings; porous and wide border of the country should subject to regular control and inspections through advanced technology products; there should be regulation that governs antisocial behaviors (i.e. harmful networks and corruptions) of law enforcement organs used to permit inflow of illicit SALW to the country; and creating awareness to all concerned law enforcement agents and stakeholders on the consequences of illicit SALW trafficking to the country.

Federalizing Federalism: Limiting the Effect of Interstate Markets on the Diversity of State Regulations

Most guns used in crime are not obtained by purchase from a licensed dealer but, rather, through informal transactions in underground markets supplied by guns diverted from legal commerce. Many major cities have units and specific police personnel investigating and curtailing criminal access to guns. The Bureau of Alcohol, Tobacco, Firearms and Explosives works with state and local law enforcement agencies to interdict trafficking, straw purchases, and illicit manufacture. These efforts attempt to reduce gun violence by disrupting the illegal supply of guns to criminals. Supply-side interventions seek to further limit illegal transactions, and they enhance the incentive for prohibited persons to economize on gun possession and use. Unfortunately, few police departments are much invested in disrupting supply. Local police departments should take a problem-oriented approach to understand how criminals access guns in their jurisdictions and collaborate with federal and state law enforcement partners to implement interventions to shut down specific gun trafficking pathways.

The article retrospectively examines the basics of forensic ballistics and forensic explosives science, trends and reasons for trafficking in firearms, weapons, ammunition and explosives in the peaceful pre-war period, as well as since the beginning of military operations in the area of Anti-Terrorist Operation and Joint Forces Operation, and in the current martial law period, and identifies trends with a forecast for the post-war perspective. At the same time, the author analyzes the current national criminal and criminal procedure legislation, including its amendments in terms of qualification and peculiarities of investigating these crimes during various periods. This research also considers its application and the ratio of its implementation in law application activities by investigators, inquiring officers, prosecutors at the stages under study, in particular, when comparing peaceful pre-war times and martial law. The study revealed that during martial law, the number of illicit trafficking cases in firearms, ammunition and explosives remains significant due to their large leakage from de-occupied settlements, from the sites of military operations, during the logistics of their delivery and, in some cases, due to the abuse of authority or negligence on the part of certain heads of military units, their financially responsible persons, violation of the accounting procedures and deficiencies in writing off these military assets. In light of the aforementioned and the consequences of illegal airstrikes, missile and artillery attacks on residential areas, educational, entertainment institutions, and other establishments, recreational facilities and civilian infrastructure of Ukrainian settlements and vehicles with civilians, the number of expert forensic ballistics and forensic explosives examination appointments has significantly increased, and therefore the workload of experts conducting these expert examinations has intensified accordingly. This requires the leadership of expert institutions to set some additional tasks in order to increase the number of experts in this category, and to conduct handwriting and forensic accounting examinations, since when keeping these arms records, interested persons fill out the relevant official document forms by hand. The author states that when considering peculiarities of actions by investigators and inquiring officers, one should take into account and comply with the relevant forensic and ballistic methods and methodologies for inspecting the crime scene with a view to a comprehensive and high-quality detection, recording, seizure and evaluation of firearms, ammunition, explosives, their components and remains as well as other objects found by law enforcement agencies after the shelling, which confirm such facts and investigation results, and will be sent to the International Criminal Court or Tribunal. It is emphasized that issues involving preparation for conducting specific types of forensic examinations remain important, including the proper formulation of questions, taking into account martial law and the use of certain military equipment, missiles and shells, which have been understudied in peacetime and require the application of additional specific expertise, and the resolution of challenging issues related to improving the efficiency of interaction between employees of the ministries and agencies concerned. Based on the results of the research, proposals and recommendations have been developed that will enhance the efficiency of pre-trial investigation and expert research in the above-mentioned promising area.
