Plenty of these kids are already getting several servings of abuse at home. That's why they show up with weapons. Kids just want to be noticed and acknowledged.
Give them a safe space to grow and they'll learn, punish and repress them and they'll lash out.
I agree and disagree at same time, some will learn that way, others only know harsher methods imo. In reality some people really just fuckin suck & can’t be helped
