They need to be outraged at the RATs who are getting school kids killed, using them as human sacrifices to further their citizen disarmament agenda.
The schools need secured entrances and exits, professional armed guards, and and trained, armed, conservative teachers.
Either that, or they need to be closed and parents given tuitional tax credits, so they can send their kids to security conscious private schools, where kids might actually learn something useful.
I forgot to add security cameras, monitored by the principal's office. It can't be that expensive, even gas station have those.
