> Why do people think it is a good thing to have this enforced by law is beyond me.
School shootings - why do we have to enforce not commiting school shootings with the stupid law, surely everyone can get together and agreee murdering a 10 year old for fun is evil and just not do it?
Kind of a ridiculous comparison. If you absolutely must compare this to school shootings, compare it this way:
Should a national government mandate only one method of security that every school must implement, or allow states/provinces/districts to experiment with what works for them? Even if the national government improves security in the short term, there is a strong possibility that the bureaucracy of national government's slowness to adapt will cause security to be worse in the long term.
