That's my friends and I in your photo of people on top of the parking garage. I'm the one with the back turned to the camera. We were actually in the correct spot but the cops didn't know what was going on and wanted everyone down on ground level to the side, where you guys were. My friend talked to a couple of the guys up there with us and they let us stay up there as long as everyone was grouped in the same spot. We explained to them what the whole event was... they really had no clue.
Here's a clip of the rudest cop everyone was annoyed with, talking to one of the masked 42 Entertainment guys and then yelling at me to get the camera off of him:

He took the paper, crumpled it up and threw it at me saying he didn't care. My friend confronted him for doing it but the cop just kept denying it, saying he threw it to the ground. I told the cop I felt it but he wouldn't look me in the eye or acknowledge me whatsoever at this point.
We met a writer from the Dallas Observer at the start of the event and he experienced some of the police drama too. Here's his article on the event:
