In October, authorities in the Dominican Republic dismantled a group of National Police officers who allegedly stole almost one million rounds of police ammunition and sold it on the black market. Some of this ammunition apparently reached armed gangs in Haiti, where violence killed and injured almost 8,000 victims in 2024 and displaced hundreds of thousands more in recent years.
Such criminal networks are not uncommon in Latin America and the Caribbean, where arms trafficking and state corruption are often deeply intertwined. This case, however, offers a rare window into how these networks operate, and how they can be disrupted.
People on the Inside
Government investigators announced on Oct. 31 that they had arrested nine National Police personnel and one civilian following an internal audit of the agency’s weapon stockpile. The network allegedly stole over 900,000 ammunition rounds and sold them illegally, laundering the profits via a tactical goods shop in Santiago. They allegedly sold the ammunition, an M16 assault rifle, and converted weapons over WhatsApp.
The suspects were all part of the National Police’s Weapons Superintendency, which manages the force’s weapons stock. They included several senior officers, namely the National Police’s weapons chief, his deputy who transported the stolen ammunition in his personal vehicle, a depot manager who orchestrated the thefts, and an auditor who falsified storage records. It also included several depot workers who smuggled the ammunition out of a depot in backpacks to evade security cameras.
The government also arrested a civilian, who allegedly received ammo from a cousin and passed it on to her ex-husband, an ammunition dealer at a market on the Dominican-Haitian border. They allegedly sold ammunition to suspected Haitian criminals. This was likely just one node of the network’s sales, as they reportedly sold illicit arms and ammo to police and military personnel, civilians with criminal backgrounds, and gun stores.
United Nations investigators monitoring arms trafficking and gang violence in Haiti first detected ammunition with National Police packaging in the possession of gang members. They reportedly passed the information to the Dominican authorities, which led to the audit. U.N. reports on Haiti have found that gangs procure much of their ammunition from the Dominican black market; this network was likely just one source of many.
A September U.N. report documented several ammunition seizures that highlight this trade. Dominican authorities seized almost 2,000 rounds from a minor attempting to cross the border into Haiti in October 2023. Police in central Haiti seized almost 10,000 rounds of ammunition from three smugglers in December 2023; they also seized 5,000 rounds from a motorcycle rider in July 2024. The seized ammunition had originated from the Dominican Republic in all cases.
Corruption at the Top
A November report from the Center for Strategic and International Studies found that corruption plays a significant role in fueling arms trafficking throughout Latin American and the Caribbean. The Dominican case demonstrates many of the basic mechanics seen in other corrupt arms trafficking networks throughout the region.
The Dominican network involved several senior government personnel and key enablers, including a colonel overseeing the National Police’s weapons stockpile, his deputy, and captains with key stockpile management roles. This level of involvement highlights how large, sustained arms trafficking networks often require senior officials to operate. In Paraguay, a multinational investigation in 2023 led to the arrest of the military’s former weapons director and several senior officials within his agency for allegedly supplying import permits to a major arms trafficker. One of the accused was a colonel responsible for the agency’s weapons registry who allegedly registered the trafficked weapons.
Senior personnel often cover their involvement by threatening, punishing, or framing low-ranking personnel, as the accused National Police officers reportedly attempted to. In 2023, a former Colombian army sergeant who managed a unit’s armory described an alleged intimidation campaign after he refused to participate in his commander’s arms trafficking network. The ex-soldier claimed that after offering him a $20,000 bribe, his superiors discharged him and apparently attempted to have him killed.
Such networks also use their privileged access to internal systems to falsify storage records. In another Colombian case, a 2023 state investigation alleged that a group of army personnel systematically falsified digital and paper records to divert over 2,000 grenades and 150,000 ammo rounds from a brigade armory. In Peru, a 2023 state investigation found that an army depot manager only had to forge his superiors’ signatures on delivery slips to steal hundreds of grenades from a central depot.
The Dominican case also shows how corrupt personnel can easily bypass physical security measures in otherwise well-secured facilities. In Brazil, investigators detained 19 military personnel after 21 machine guns – including several U.S.-produced Browning M2 heavy machine guns – disappeared from a central armory in 2023. The theft occurred during a power outage, allowing the perpetrators to bypass the facility’s security cameras and alarm systems.
The Dominican network also shows how front organizations, often in security-adjacent fields, are key to facilitating illicit sales. In the 2023 Colombian investigation, prosecutors alleged that a retired soldier used his private security practice as a mechanism for selling stolen grenades and ammo and laundering the profits. A 2020 investigation revealed that a Panamanian arms trafficker used a gun club to import rifles with permits he obtained from corrupt officials before selling them on the black market.
Countering Corrupt Networks
These cases show how States can better combat such networks. Responses must include improving detection, managing personnel more efficiently, and hardening stockpile security measures.
The Dominican case shows the value of detection mechanisms. The network was detected thanks to the work of highly skilled U.N. investigators in neighboring Haiti. Throughout the world, U.N. expert panels are essential to detecting arms trafficking trends and embargo violations. Such work can also be carried out by government fact-finding missions or investigative media outlets. Governments should also create mechanisms to incentivize and protect whistleblowers who call out corruption and misconduct.
Independent auditing bodies are also indispensable. State forces and agencies that maintain weapons must have an independent body with extensive jurisdiction for conducting frequent, randomized, and spontaneous audits of arms storage sites. Units should also be staffed with externally trained and accountable depot managers, responsible for conducting regular and randomized inventories while also ensuring arms and ammunition are well-documented at the unit level.
Information sharing and multilateral cooperation are also crucial. Many of the previous cases were discovered after the authorities received credible intelligence from a foreign government or international body. The 2023 Colombian investigation was launched after the United States shared intelligence about a group of soldiers selling state weapons to armed groups. The 2023 Paraguayan case also took place after a joint investigation between Paraguayan, Brazilian, American, and Interpol officials.
States must also manage their personnel more effectively. The Dominican network allegedly relied on senior and mid-level personnel in key stockpile management roles. Personnel may pursue corrupt opportunities to supplement poor pay, or to gain internal bribe money necessary for promotions. Due to the sensitivity of their roles, governments should offer key personnel performance incentives such as supplemental pay or surety bonds.
Incentives should be paired with increased scrutiny, such as background checks and regular asset disclosures. Brazilian authorities arrested a military police captain suspected of leading an arms trafficking network in 2024 after he posted images of his opulent vacations on social media. In another case from 2021, a Brazilian police commissioner allegedly used the illegal profits he made from selling hundreds of weapons to buy a beach house under his daughter’s name. Personnel in key roles should also be rotated into different posts regularly to prevent them from abusing their access to government weapons.
The Dominican case also demonstrates how physical stockpile security measures – anything from security cameras, locks, fences, to arms tracking software – can be easily defeated by corrupt personnel. International donors tend to favor projects that enhance technical security measures because they are politically safe and easy to measure. Yet these cases demonstrate they are not sufficient to secure state weapons from corrupt government personnel.
Even so, physical security measures are necessary, and many States could do more to modernize and streamline their technical security measures. Arms traffickers are adept at exploiting technical inefficiencies, and many state forces still use paper records (which are easily falsified) for tracking weapons. Some use outdated or decentralized digitized systems that are vulnerable to abuse. Arms management systems must be centralized and digitized with built-in transparency features that prevent records from being discreetly altered.
Securing State Stockpiles Is a First Step
It is important not to overstate the role government corruption plays in arms trafficking. Throughout Latin America and the Caribbean, the sources and mechanisms that drive arms trafficking are varied. The greatest source of trafficked arms and ammunition is undeniably the United States, where civilian gun laws are notoriously weak and can be exploited by any bad actor. A U.S. Senate committee estimates that up to 500,000 U.S.-origin weapons are trafficked to Mexico per year. Researchers have also shown that almost half of U.S. gun dealers are reliant on Mexican demand.
Nevertheless, corruption still plays a very significant role – especially for arms and ammunition that are not readily available on the American civilian market, such as grenades, explosive ordnance, automatic firearms, and light weapons. The scale of violence in countries such as Haiti requires a massive and constant flow of ammunition that so-called ant trafficking (or small continuous shipments) from the United States may struggle to meet. The enormous demand for weapons in the region puts a premium on securing state stockpiles from corrupt officials who might sense a profitable opportunity.
