I agree with the problem you identify. I was both a bully, and a bullied person at times during my school days. For me the bullying of me brought on the bullying by me, I feel.
I don't see any practical answers in your comment. Recognising schools should "makes it safe to report bullying" is one thing. How though? It seems entirely intractable - you seem to suggest blanket surveillance of all children everywhere?
You don’t need surveillance if you have relationships and trust. Bullying is intractable because traditional schooling is essentially and structurally exactly that: the bullying of kids by adults. It’s only logical that it results in the bullying of kids by kids.
Make teachers (and parents) people of trust, not only of arbitrary authority, and you create options to address bullying between kids as well.
