Yet Again.

[Nick Real Deal]

There should be limited entry points and perimeter fencing like prisons. A9+

Afraid I'd have my kids down the gun range and sending them into School with a Glock in their satchel., unless the school scanned all bags at entry and had armed security around on every entry point during the day - how else could you have any peace of mind?

They need airport type security or prison type with perimeter fencing and controlled entry points. Money should be no object.
