seems a bit extreme, why not just demolish all schools and build them to the plans from broadmoor.
schools are relatively safe (certainly given the massive footfall of people that need to move around them quickly, safely and efficiently)
isnt the issue with those of a fragile and dangerous mental state getting access to guns before they get access to proper medical/psychological treatment, rather than redesigning schools so that they are highly secure miserable grim places that to the students feel like concentration camps rather than places to learn and achieve? (im aware some schools are like that anyway).,
ive worked in a number of schools where they have some sort of security measure, for example you cannot get any further than reception without being "allowed in" and all but the main entrance is closed during school hours, a system designed to keep a wriggle on who is coming and going rather than keep the place on lockdown.
