“Sue the living crap out of them.”
I totally agree. I don’t usually favor litigation, but there are a lot of hungry attorneys out there, and if you want to fight back against this kind of nonsense you have to do things that get their attention.
I understand being strict with school entry rules, but the school called her, recognized her, and she had just met with the principal. I would not doubt that there was some conflict between them before this (why was she meeting with the principal the day before), and they used this opportunity to get back at her.
Bingo. Almost certainly this was a retaliatory move.
But suing will only hurt the taxpayers, not the government employees, I’m afraid.
