ATF Statistics about US guns to Mexican Drug Cartels DEBUNKED!

Fox News has done some actual investigative journalism and found that the statistics being thrown around by the Obama administration and parroted by the media are false.  The real analysis shows that 83% of the guns siezed from the drug cartels by Mexican authorities over the last two years DID NOT originate from the United States.  Now I wonder how much of that 17% were sold, legally, by the US government to the Mexican government and then made their way into the wrong hands through corruption and desertion by Mexican military personnel.
