ATF gunwalking scandal
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) ran a series of "gunwalking" sting operations[2][3] between 2006[4] and 2011.
[2][5] This was done under the umbrella of Project Gunrunner, a project intended to stem the flow of firearms into Mexico by interdicting straw purchasers and gun traffickers within the United States.[6] "Gunwalking" or "letting guns walk" was a tactic whereby the ATF knowingly allowed thousands of guns to be bought by suspected arms traffickers ("gunrunners") working through straw purchasers on behalf of Mexican drug cartels.[7]
The stated goal of allowing these purchases was to continue to track the firearms as they were transferred to higher-level traffickers and key figures in Mexican cartels, in theory leading to their arrests and the dismantling of the cartels.[8][9] The tactic was questioned during the operations by a number of people, including ATF field agents and cooperating licensed gun dealers.[10][11][12][13][14] Operation Fast and Furious, by far the largest "gunwalking" probe, led to the sale of over 2,000 firearms, of which around 700 were recovered as of October 20, 2011.[15] A number of straw purchasers have been arrested and indicted; however, as of October 2011, none of the targeted high-level cartel figures have been arrested.[7]
Firearms "walked" by the ATF have been found at violent crime scenes on both sides of the Mexico–United States border, including scenes involving the deaths of many Mexicans and at least one U.S. federal agent, Border Patrol Agent Brian Terry.
The "gunwalking" operations became public in the aftermath of Terry's murder.[2] Dissident ATF agents came forward to Congress in response.[16][17] As investigations have continued, the operations have become increasingly controversial in both countries, and diplomatic relations have been damaged as a result.[2]
