Coming home tonight, I was startled to see armed National Guardsmen outside the terminal at Grand Central Station. Back at the Brooklyn bunker, I logged on to see the headline on Drudge, in which the FBI has issued a warning this evening cautioning against “spectacular attacks” by al-Qaeda. I had forgotten what this city is like with soldiers packing machine guns standing on the corner. Don’t get me wrong, I’m glad they’re there. I wish they didn’t have to be.
