This kind of thing hits very close to my own, as I was also in a similiar situation. School basically didn't give a shit, and even got to a point that they started blaming
me
for every single incident to the point they legit removed me permanently from school grounds because I'm a "violent threat" that needs to be removed/drugged up. It took me 21 years to learn the truth, and yes karma is a bitch.
Without my doing or desire, 3 of my bullies died not too long after, and the one lying teacher and principal (they were married, so a total conflict of interest) lost everything they and their families owned in a single hurricane.
My condolences to Sammy, but sadly it's not an isolated/one off thing.
