Time reports this week that an al-Qaeda document that turned up last year titled “Rogh Presentation for Gas Limo Project” gave officials the idea that they should be looking out for limo bombs during the inauguration. The way Time puts it, the memo went around security circles on Jan 5 and “In response, barriers have been set up to block any vehicle bent on destruction.”

Not to doubt our protectors, but I really hope they didn’t need that memo to be thinking along those lines.
