Mexico is awash in violence. And the country’s stringent gun control laws aren’t helping.

On Feb. 22, the Mexican military carried out an operation that killed Nemesio Oseguera Cervantes, nicknamed “El Mencho,” the leader of the Jalisco New Generation Cartel (CJNG). Mexican armed forces were reportedly trained by a small cadre of U.S. Navy SEALs who entered the country on a “training mission” approved by Mexico’s Senate.
