CBS News: 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.
Law enforcement sources say Kingery could have been prosecuted in the U.S. twice for violating export control laws, but that, each time, prosecutors in Arizona refused to make a case.
