Unfortunately, with school crisis situations, it's about mitigating loss.
The police largely prevent crime only by accidentally being in the right place at the right time or by use of inside information. Otherwise all police work is about filing reports and mitigating loss. The fact that it's an incident at a school isn't relevant.
I'll go so far as to say that 95% of people are probably biologically capable of going to college.
With all due respect you're about 70% too high. If you honestly believe that all we need to do is "straighten out" our education problems by fixing only the educators you will be very disappointed by the results.
