68,000 guns seized in Mexico since 2006 came from US

I guess those guns make Mexico a freer nation as NRA argues:

 68,000 guns recovered by Mexican authorities in the past five years have been traced back to the United States, authorities said Friday.

The flood of tens of thousands of weapons underscores complaints from Mexico that the U.S. is responsible for arming the drug cartels plaguing its southern neighbor. Six years of violence between warring cartels have killed more than 47,000 people in Mexico.
