Join Stop U.S. Arms to Mexico, Global Exchange, Community Justice, legal experts, attorneys, and advocates as we listen to the Mexico v. Smith & Wesson oral arguments and discuss the case’s implications. This landmark case marks the first time a sovereign nation has sued the U.S. gun industry to hold manufacturers accountable for facilitating illegal gun trafficking and marketing weapons favored by cartels.

On March 4th, the U.S. Supreme Court heard opening arguments in Mexico v. Smith & Wesson, a landmark case seeking to hold U.S. gun manufacturers accountable for the deadly impact of their products in Mexico. This case marks a pivotal moment in the fight against gun violence—one that could set a major precedent.
At Global Exchange, we know that facts and the voices of impacted communities are our most powerful tools in this fight. And today was proof of that.
Research conducted by Global Exchange’s Stop U.S. Arms to Mexico program on U.S. firearms trafficked across the border provided the Mexican government with evidence used in the case.
This morning, we gathered with supporters for a listening session of the Supreme Court arguments, where we heard from experts on the case’s legal complexities and, most importantly, the profound human toll of firearm violence in Mexico. If you missed it, you can listen to the arguments here.
Yesterday, John Lindsay-Poland, founder of the Stop U.S. Arms to Mexico program, was interviewed on The World about his groundbreaking research tracing U.S.-made guns to homicides in Mexico. More than 70% of guns used in homicides in Mexico originate in the United States—a staggering statistic that underscores the urgent need for change.
Today, we also took action at the highest levels. We sent a letter to the White House, signed by dozens of faith, peace, gun violence prevention, and organizations, demanding that President Trump uphold his promise to Mexican President Claudia Sheinbaum: to stop the trafficking of high-powered weapons into Mexico. Read our press release here.
As Trump moves to designate cartels as foreign terrorist organizations and the Supreme Court hears Mexico’s case, we urge the administration to confront the root cause: the unchecked flow of U.S. firearms that fuels violence, strengthens cartels, and forces families to flee their homes.
“U.S.-sourced firearms are enabling cartels to devastate communities, fuel the narcotics trade, and intimidate local authorities—forcing migration from Mexico to the United States.” – from our letter to the White House.
No matter what happens in court or in Washington, our fight continues. We commit to doing everything we can to stop the flow of U.S. guns into Mexico.

This week, the US Supreme Court will hear a case that places some blame for cartel violence in Mexico on gunmakers in the US. The Mexican government argues that the firearm industry enables the trafficking of guns used by cartels. Host Marco Werman discussed the case with John Lindsay-Poland, of the advocacy Group Stop US Arms to Mexico.
An iron river of weapons flows from the United States to Mexico, empowering criminal organizations and accelerating forced migration through chaos and violence. The river of guns has its headwaters in the United States, originating from hundreds of gun manufacturers, passing through thousands of local U.S. gun dealers before eventually finding its way into Mexico.
In reaction to the flow of illicit weapons, a firearms race has developed, in which gun companies export more and increasingly militarized weapons to Mexican police and military forces.
As a result of the flood of weapons, the number of lives lost or disappeared through violence in Mexico continues to increase, while migrants fleeing through Mexico have become understandably more desperate to get to safety. Political discourse focuses on the U.S.-Mexico border. But the unregulated, massive and militarized U.S. gun market that feeds the violence, drug trafficking, and displacement is growing – and often ignored.
The Stop US Arms to Mexico project obtained finely grained data, never before disclosed, on the origins of guns trafficked and exported to Mexico and Central America from the United States since 2015. This data, and the visualizations assembled, provide a clearer picture than ever before of the extent of the weapons being sold and trafficked.
The full report is available here: stopusarmstomexico.org/iron-river.
You can help us slow this river of weapons. We have a critical opportunity to make a real difference in the fight against gun violence and arms trafficking by organizing support for the ARMAS Act (H.R. 6618) and Stop Arming Cartels Act (H.R. 8427 / S. 2926).
Join us! Call or Write your Congress Member and ask them to co-sponsor these two life-saving bills!
Gun violence in Mexico, the United States, in Central America, Haiti and other countries in the Americas has created chaos and heartache on an unimaginable scale. We can do something to stem the tide of violence.
The Iron River can be stopped with the courage and commitment of people like you. Thank you.
We will never give up demanding justice for the disappeared.
Right now, the family of Ricardo Lagunes Gasca and representatives of Antonio Díaz Valencia are in Washington DC, meeting with policy makers and the international diplomatic community to push for answers and to demand accountability.
Ricardo Lagunes Gasca, a human rights and Indigenous territories lawyer, and Professor Antonio Díaz Valencia, the leader of the Nahua Indigenous community of San Miguel de Aquila, Michoacán, Mexico, were victims of enforced disappearance on January 15, 2023 for successfully defending Indigenous rights in courts.
They violently disappeared after participating in a community assembly discussing the next steps after winning the case. There are allegations that both received threats from Ternium, the company operating the Aquila mine – a company that has received scrutiny for its blatant disregard of Indigenous rights in the region.
Unfortunately, the plight of Ricardo and Antonio is far from unusual in the region. Between 2002 and 2023, 96 environmental defenders and 62 Indigenous Rights activists have disappeared.
Since their disappearance, Ricardo’s relatives have been demanding a full investigation from the United Nations Committee on Enforced Disappearances and Inter-American Commission.
Ana Lucía and Antoine Lagunes Gasca, Ricardo’s siblings, are visiting Washington D.C. this week, from November 8 to 11, for a meeting with the U.S. State Department’s Task Force of Environmental defenders, a private hearing with the Inter-American Commission, the Office of the High Commissioner and the Mexican Government, and with several allies.
They are seeking support from the international community and international organizations to advocate for the return of both defenders and achieve international technical assistance in the search and investigation in order to seek their humanitarian recovery, find the truth and seek justice in the case.
Watch a video (in Spanish) featuring the families of Ricardo and Antonio below:
One of the key demands of the People’s Movement for Peace and Justice is accountability and justice for the disappeared. Further, Global Exchange has been an ally of human right defenders in Mexico for over 30 years. Our Mexico Human Rights Senior Fellow, Alberto Solis, was contacted by the families and the lawyers of Ricardo and Antonio to support them in their visit to DC. We will be with them to make sure the US State Department follows up on their commitments with the case and the victims. The People’s Movement for Peace and Justice stands with these families, and with all the families of the disappeared.
