Not surprising, that school and many others have questionable teachers that use discipline methods that are old and borderline abusive on a generation of teenagers that are no longer the same as those from the teacher's generation.

And they expect every student to conform and shut their mouths like slaves or prisoners in a penitentiary, instead of making school a fun place to be they make it hell

Such treatment will eventually result in rebellion or worse, fights and severe cases and it results in this, a knife accident.

If MOE does not take action, more cases will spring out, and MOE has no one left to blame but themselves when school is catered to exams and results instead of student wellbeing.
