I'VE BEEN CRITICAL OF HOMELAND SECURITY FOR SOME TIME: This report does nothing to increase my confidence: "In today's security-obsessed, post-9/11 era, one might think that it would be difficult to haul a convincing replica of an atomic bomb across the country. Not so, as John Coster-Mullen inadvertently proved in October 2004."
UPDATE: Famed blog-commenter Cecil Turner (well, he is) emails that I'm wrong:
In the first place, the logical method for terrorists employing a nuclear weapon is by placing one in a shipping container and detonating it in a US port. Hence the security arrangements should be oriented outward from the ports, not inward toward the highways. In the second, as articles like this one make clear, such devices are detected by scanning for their radioactive material--not by their realistic-looking cases. While I'd probably agree homeland security is less than impressive, this is not a good example.
