AJC: Border guards fail bomb test

A scary story from ajc.com: "Undercover federal investigators say they were able to drive into the United States from Canada and Mexico last year with enough radioactive material in the trunks of their rented cars to build two so-called dirty bombs.

The exercises, conducted on Dec. 14 at unidentified border crossings, were carried out by the Government Accountability Office at the behest of the Senate subcommittee on investigations, which has been analyzing security at ports and border crossings."
