So I went to the memorial on 4 July... Didn't see any dancing. Did go through a few checkpoints that day. None of the cops were intimidating, authoritarian, or even dicks. Only one of the 9 (5 museum, 4 monument) even stopped me for my multitool. Many of the officers were friendly, joking around and smiling, and/or professional. I even had my camera out for one or two of them. I understand Meg and others had some difficulty. I wonder why there is such a difference in our experiences. Time of day, group, demeanor? Maybe its just that I'm a sheeple?
