Looking at photo it appears the tables are inside the gym ( wooden floor of gym visable) Did kids barricade themselves in?
Another question. Were kids being supervised at the time. I taught 7 years ago and leaving kids unsupervised was a serious violation, even emergency bathroom trips required us to get coverage.
Possibly. Go to the click-bait site and look at the following picture. These are not little kids.
I do think they were segregated away from their classes for not wearing a mask. I am not sure we are getting the whole story.
In fact, look at the twitter video very slowly...
Where exactly are those doors from the picture? Where are the tables?
