Is there no end to this?

Kudos to Sharyl Attkisson for sticking to this story.
"Grenade-walking" part of "Gunwalker" scandalCBS News investigative correspondent Sharyl Attkisson, who has reported on this story from the beginning, said on "The Early Show" that the investigation into the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)'s so-called "Fast and Furious" operation branches out to a case involving grenades. Sources tell her a suspect was left to traffic and manufacture them for Mexican drug cartels.
Police say Jean Baptiste Kingery, a U.S. citizen, was a veritable grenade machine. He's accused of smuggling parts for as many as 2,000 grenades into Mexico for killer drug cartels -- sometimes under the direct watch of U.S. law enforcement.

Attkisson added on "The Early Show" that, in August, Mexican authorities raided Kingery's stash house and factory, finding materials for 1,000 grenades. He was charged with trafficking and allegedly admitted not only to making grenades, but also to teaching cartels how to make them, as well as helping cartel members convert semi-automatic rifles to fully-automatic. As one source put it: There's no telling how much damage Kingery did in the year-and-a-half since he was first let go. The Justice Department inspector general is now investigating this, along with "Fast and Furious."
