Gun Control & RKBA

From 2009 to 2014, more than 73,000 guns that were seized in Mexico were traced to the U.S., according to a new update on the effort to fight weapons trafficking along the U.S.-Mexico border.

The figure, based on data from the Bureau of Alcohol, Tobacco, Firearms and Explosives, represents about 70 percent of the 104,850 firearms seized by Mexican authorities that were also submitted to U.S. authorities for tracing.

The data was analyzed by the Government Accountability Office, which notes in its report that U.S. police agencies have acknowledged firearms smuggling is fueling violent crime in Mexico.
Many of those guns were bought legally in the U.S. and then smuggled over the border, according to the GAO.
