Nothing changes, I have left school 18 years when i was 15 I ended up in hospital with a skull fracture, broken cheekbone, concussion unable to see out of both eyes all due to bully's, the person involved for a slap on the wrist from the police and it was my next door neighbor.
The nanny state has a lot to blame for this you cant punish them because "they are only children"
The more it happens the more we become desensitized to it and so the nanny state continues...
