If the woman refused to put a mask on after being asked repeatedly, was told she had to leave the stadium if she didn't, and refused, the cop was right.

Perhaps the mask policy is stupid, but making policy decisions isn't the cop's job. The school is entitled to set rules for who goes on its property, and to eject from its property people who are not following those rules. She brought it on herself by not following the cops' lawful order.

Actually it is the cop's job to know when something is illegal or allowed. They send them to school and they are continually taking classes to know what is legal and what is not. This was not. And he knew it or should have.

The school is entitled to set rules for who goes on its property, and to eject from its property people who are not following those rules.

And no. They have very tight restrictions on the rules they may set and who they may eject. She did not fall under their restrictions so was not doing anything she could be ejected for.

She brought it on herself by not following the cops' lawful order.

It was not lawful. That is the problem.
