In a shocking development in the Operation Fast and Furious  investigation, documents show Bureau of Alcohol, Tobacco, Firearms and Explosives agents allowed grenade parts to walk in addition to guns.
The emails also show Obama administration officials acknowledging that they may lose track of grenades but would still be able to accomplish their original objective even if the grenades explode.
According to an internal email that was provided to Congress by the Department of Justice and first reported  by CBS News’ Sharyl Attkisson, ATF began watching accused smuggler Jean Baptiste Kingery’s AK-47 purchases in 2004. In the 2009 internal ATF email, Obama administration officials admitted they believed Kingery was “trafficking them into Mexico.”
The 2009 email shows the ATF officials had then become aware of Kingery’s alleged grenade trafficking.
