Is there room in the Obama administration for one more scandal? CBS investigative reporter Sharyl Attkisson is following the death of three Mexican police officers killed in a shootout with a drug cartel last week, apparently with grenades walked across the border from the United States.

Attkisson says that it’s not quite Fast and Furious, although the same Arizona ATF office and attorney that oversaw that scandal hatched a plan to let Jean Baptiste Kingery smuggle weapons parts into Mexico, with the idea of tracking him to his factory. The ATF reportedly lost track of Kingery, finding him in 2010 but not having a good enough case to arrest him.

Says Attkisson, Kingery was “allowed to operate for years without arresting despite significant evidence that he was moving massive amounts of grenade parts and ammunition to Mexico’s ruthless drug cartels.” The Mexican police finally raided his factory in 2011 and accused Kingery of teaching his clients how to build their own grenades and also convert semi-automatic weapons to full-auto.
