The trafficking of weapons over the U.S.-Mexico border is well-documented — lesser known but also significant is the sale of U.S. weapons to Guatemalan government contractors, which are then siphoned off to criminal groups.
The Mexican government has focused much of its efforts to stop arms trafficking on the smuggling of weapons over the U.S. border.
