They've really cranked up the security here on Capitol Hill as a result of the vague Al Qaeda threat made public just before 9-11. The short metal fences that block cars from getting close to the Capitol are up. I've seen two bomb-sniffing dogs this morning - one outside the office of House Majority Whip Kevin McCarthy. And there were security personnel of all stripes waiting outside the Congressional meeting room where US mayors were meeting with House Minority Leader Nancy Pelosi. Bag checks are thorough. Haven't spotted any of the submachine guns I saw the night President Obama came to address Congress. Yet.
