This link explains an approach that is more solution-focused and realistic in a school system in my opinion. Zero tolerance is unattainable and impossible to enforce. This is doable!

Might want to see if the kid who had his arm broken recently by bullies at school wishes to talk about the incident afterwards. Or what his parents would think of restorative justice.

I’m sorry that happened to someone. That is awful.  
I do stand by what I said regarding restorative practices. Is this issue ongoing? The problem is usually the issue continues even after coming to a head without any problem solving between the parties involved. It is also extremely emotionally damaging to be bullied (obviously), and this helps one another understand what their perspective is and how they can move forward. It may take time to be ready  
to try it, but may be of significant long-term benefit to try the approach.
