He told me that just now, by phone. He got out, and is warning others not to go in. Obviously, it's a terrible fire hazard to make it so people cannot get out of the building easily. Presumably, protesters think it's a good idea to keep the police out, but it is dangerously stupid.
ADDED: Meade called back to say, some of the doors are handcuffed shut and some are wide open. "ANYBODY CAN GET IN AND ANYBODY CAN BRING ANYTHING IN. THERE IS ABSOLUTELY NO SECURITY WHATEVER."
AND: Meade — who just got home at 9 CT — says the police have the "fairly calm jocose" attitude that they've had all along. They have no riot gear, he said. The place is "swarmed" with protesters. Photos and video soon.
