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.
