A 17-year-old smuggler in Arizona is handling up to 200 weekly firearm orders for the Sinaloa Cartel, illustrating the explosive growth in U.S.-origin weapons flowing into Mexico. This surge occurs despite President Trump's crackdown, which traffickers claim is easily circumvented. The teenager operates from a smartphone, sourcing weapons from American gun shops, shows, websites, and apps, then smuggling them across the border using methods like hidden compartments and private planes.

The flow of weapons, estimated at potentially 500,000 to one million annually, fuels cartel violence and undermines Mexico's crackdown efforts. Mexican authorities estimate up to 500,000 guns cross annually, while ATF seizures represent a tiny fraction. President Sheinbaum demands U.S. action to stem the flow, highlighting the cartels' access to military-grade weapons like grenade launchers and machine guns.
