Sep 28, 2007 — Investigators for the Government Accountability Office say they were able to smuggle fake contraband designed to look like a dirty atomic bomb into the United States.

As Brian Mann reports, there's a growing bipartisan consensus that the Bush Administration's strategy for security on the northern border isn't working.
