You'd be surprised how many Principals don't "have a spine". After some 40ish years of dealing with schools it comes as absolutely no shock to me.
Last year, a kid in my daughter's middle school, started threatening other kids, both in school and out (on social media) .
My Daughter shows me a group chat one night where the kids says:
"(Safeguard's little) Better stop sticking up for, (her friends name), or she could get hurt, or worse "
Another student asks him, "what do you mean, or worse??" And he replies,
"She could get killed" "Let's just say it involves a knife" but I'm not going to kill anyone yet."
I took her phone to the school, and showed it to them, (there were other messages he sent to the group chat, about rape and violence directed towards specific children including my child that I can't even post here they are that vulgar. ), You know what was done?
They took pics of the messages, had a meeting with his parents and suspended him for ONE day.
Principle literally said to me, "Sometimes good kids make poor choices" .
