That might be the case for certain things Grumpy.
But I can assure you that if a teacher thought they were going to stand in as a loco parentis whilst my daughter was strip searched by the Police without my knowledge or consent - That teacher would very quickly understand the meaning of going loco.
Early 00s DodEd issued a memo authorising teacher supervised searches, staff had to have appropriate training though. Take it up with your MP, I'm afraid, as it's already happened.
