In this case, I’m referring to Robyn Hooker, principal of Kent Gardens Elementary School in McLean, VA, who issued the edict because tag had become a game, “of intense aggression.”
One of the peculiarities of being a principal in the US, at least at public schools, is that you cannot work your way up through the ranks. You have to get a certification specific to being a principal.
Generally, this means that either you went in with the goal of being a principal, i.e. that you wanted to be “in education” but you did not want to teach, or you decided that you really didn’t like teaching that much.
So you get profoundly dysfunctional people like this, who think that any problem, and it appears that the tag was getting a bit rough can be solved with a mindless punitive over-reaction.
What’s more, they lack adult supervision, which is why teachers’ unions are the way they are. Would you want to work for someone like her?
