Being a former Paramedic, I cannot imagine what you have had to deal with during this. But I hope that someone pulls their head out of their BUTT and does something. I cannot tell you the horrors I have personally seen just with school violence, but it can only get worse as the kid gets older.
The zero tolerance is BS, I see it on my local school, and where my son now goes to college. We all need to go back 30+years and do things like we used to. Not that I enjoyed getting a beatin for things I did, but we were better adjusted I think IMO. We had a shooting range in my high school, and we could walk down the street to the school with our gun, no police SWAT team meeting us at the entrance.
I hope everything works out for you with NO problems. We send our kids to school to learn and this is what you get...sad
