Nope. It was in immediate reaction to the shot.
The barricade of all the chairs and furniture stacked up on the inside of the locked doors.
The intact window were almost certainly bullet resistant.
Everyone was surprised at the shot, because there was no warning.
In a one shot situation like that, everyone is trying to figure out what happened.
At first, you do not even know where the shot came from, for sure.
It takes seconds to process what is happening.
Babbit is surrounded by anything BUT uniforms.
The shot had already occurred when young SWAT shows up, sort'a pulls up, and drops for a thumbs up
The intact window were almost certainly bullet resistant.

In the 21 min video, we see that the partition windows are easily removed plastic panes, not anything special;
We see several prominently identifiable “rioters” quickly changing their clothes and appearances as they leave the scene;
Every one is not surprised; there is no reaction from the “cops”. There is no attempt to put up crime scene tape or clear the crowd. One cop even steps in the tiny blood spot and smears it around;
We know where the shot came from, as the professional cameraman is waiting to film as the gun pokes out of the closet on the other side of the hall partition;
Then toward the end on the video, several bystanders say, “They are all actors”.
