I wonder if it was a close call between going to orange or going straight to red? Of course, orange could be prelude for red if the threat information becomes even more specific in the next 48 hours. And, since we've never had a red (severe) threat level, red may create a certain amount of panic to add to the uncertainty already existing.

My question is this: how hard would be for a Middle Eastern cab driver to turn his cab into a car bomb? I mean, when you think of the number of Arab cab drivers in NYC, DC, etc., wouldn't this be the perfect cover for them? Cabs go everywhere in major cities...
