This is just another point proven that the schools need to have trained personal to protect the schools. You can put a cop out there with just basic police training skills. Put a Vet out there who has a background in protecting and serving. In the big picture of things all America has been doing is showing the world how unprotected our schools are. On that thought alone we are opening ourselves up to an attack on our children much like 911 if not worse.
You can't ever lead the blind.
