"Don't want" and unwilling are different statements. My argument is to quit coddling these crazy people and lock them the hell up instead. It's always the crazy people that do things like schools and churches. Fix the crazies and no one is going on school rampages anymore. The other criminals want profitable enterprise not suicide. We went a very long time without the need for secured schools and instead of fixing the problem everyone wants to secure things.

I worked at schools for a handful of years. Mostly IT support, but I was licensed for security systems at the time so occasionally I did some install and maintenance of security stuff. The amount of effort required to secure a school in such a way that the school business can still go on normally would be absurd. There's too many points of ingress/egress and too many variables to control, local codes that get in the way, etc. Then when you have an inside job like has happened in the past with someone pulling the fire alarms for example, it all goes out the window because it's required to by code.

I guess some security theater in mag locking the front door like that might serve as a deterrent, or at least keep the honest people honest. As would what in reality amounts to one or two armed guards on payroll, there's no way they can cover all the variables.
