Sunshine is the best disinfectant, looks like it will be taken care of not just in this district but a lot more now that this amount of anger is being shown nationally.
I recently retired after 32 years (rural school +700)they do have an armed police officer in our school at all times.
I must say though that our intruder alert drill concerns me. Luckily I taught science, and the first thing to greet anyone who broke into my classroom would be a liter of HCL in their face.
