The auditors would certainly be dedicated actors if they aren't on our side because they are doxxed and vilified daily by most news: this is a friendly source. The graduations have happened many times before. The auditors may have known about it and either hoped to be done or realized that there is a huge amount of enclosed space with controlled access at the fairgrounds for a temporary retreat with their 19 armed guards. You aren't even seeing all the Coliseum space on these cameras, only the main arena floor. Antifa and BLM don't get much traction around here, they would be targets if they started getting in people's faces.

EDIT: I've spent a few minutes today trying to find just which HS are using what facilities for graduation. Five from the NW valley, Deer Valley district,q are going to the State Farm Arena (Cardinals stadium), a much glitzier place, on the 20th and 21st. Many schools have their own assembly room or stadium; for instance, Carl Hayden, the closest one. So far I haven't found a name to associate with the Coliseum. Charter schools? Who? This is starting to look like the carnival that flopped, like a planned interruption. The insider anon said today the manager of the Coliseum wanted to shut things down 10 days for maintenance, but the maintenance chief is getting it done in 5 days.
