I haven't heard the full account yet from our friend who was there (the one who reported the NPS wetting down the mall on Jan. 5 to make it muddy and gross for the coming Trump supporters), but he noted that as soon as he and his buddies detected a commotion at the Capitol end of the mall, they hightailed it to the Smithsonian Metro stop and got out of there. I suspect that describes 99.99% of those in attendance, considering the numbers that actually entered the Capitol building.
