For one, I like the idea of creating some degree of systems of support to try and prevent things like school shootings from happening by stopping them before they get too far.
On the other hand, unless there are more details missing from this article, it really seems like the only person who got any degree of punishment is the student who was being bullied.
You know what stops bullies that doesn't involve shooting them? Ruthless consequences for their actions. Schools love to talk about their 'zero tolerance' policy for bullying, but if there are no consequences outside of a teacher telling the bully to stop, then that is definitely less of a 'zero tolerance' policy and more of a 'mostly tolerated' policy. Zero tolerance means immediate suspensions, expulsions, supporting police reports for physically violent bullying etc.
