There’s another video with helicopter footage of the school parking lot. It was called “concrete cowboys.” It showed the school parking lot that day and the cars were all parked in the same direction. Next regular parking lots were shown with cars parked in either direction randomly. Then it showed event parking with the concrete cowboys flagging cars into spots just like the school parking lot. It was a staged event, including the parking for the participants
I never saw the video again, it was quite compelling..
