You're absolutely right. Camera crews are never in the building on a daily basis, particularly during session. Never. True, many were along for the ride, and law enforcement assessed them - correctly - as non-threatening. The one thing that's true was there was an element, or elements, intent on mayhem, and others were caught up in it. It was not a scripted military operation.
I know I'm not going to change your mind, but from time to time it's necessary to shine the light on your slurry with the fringe on sop. I guess that civil war is right around the corner.
