So, a quick recap:
About 5100 guns, 90% of the 6,000 traceable guns of the 11,000 guns shipped to the BATF of the total of 29,000 guns seized by Mexican authorities were traceable to U.S. sources.
5100 divided by 29,000 is 17, almost 18% of all guns seized last year were of U.S. origin. NOT 90%. Seems to me that it'd be better for China, Guatemala, etc. - OTHER countries to implement gun control. Oh, wait. Those countries already have in place draconian gun control laws.
