The following cut and paste is from an article in Pajamas Media in 2009:

"The myth that legal guns sales in the United States are responsible for Mexican drug cartel violence took another serious blow last week when an ATF official testified in Congress that only eight percent of weapons recovered in Mexico came through licensed U.S. gun dealers.
This figure is far lower than the 90 percent claim made previously as an appeal to reinstate ineffective gun laws that expired in 2004. The claim — still active among the less informed or serially dishonest — officially became myth during congressional testimony last week when , revealed the eight percent figure, how it was calculated, and where the 90 percent myth arose from.
Of the 100,000 weapons recovered by Mexican authorities, only 18,000 were determined to have been manufactured, sold, or imported from the United States, and of those 18,000, just 7,900 came from sales by licensed gun dealers."
"Only eight percent of guns recovered from cartels in Mexico originated from legal gun dealers in the U.S.: not 90 percent as Obama has claimed."
Kind of puts the lie to the common myth that the guns come from legal sales in the US.
Don't they listen to their own? "Bill McMahon, deputy assistant director of the Bureau of Alcohol, Tobacco, Firearms and Explosives" has stated in the above their figures are flawed.
Oh well, internal consistency is to much to expect.
