I hear a bunch of N thing needs to happen, but the question is will that N solution help. The question to ask is, has someone run a study on N solution, and if so what's the next best solution. Gather data like where are the things of interest happening e.g. region of city. Make shore that N solution does not try to fix a symptom and disregard a source problem. Is N thing is symptom there can be many sources which have different solutions.
Obviously there's a solution! Give underpaid and abused teachers guns and ask them to shoot a teenager with zero followup on mental health for the teacher!

Genuinely makes me sick how many people have said this to me, that teachers just need to be armed
When I had two fellow teachers tell me (not at the same time, like a week apart) that they agreed and wanted their rights respected so they could carry at work, well, I figured it was about time for me to bow out of the profession.
