Why? Because it endangers their health, and could easily go wrong.

While your analogy is interesting, I believe it's important to distinguish between the two scenarios. The knife-wielding scenario involves a toddler, who lacks the understanding and capability to make informed decisions. In the school context, we're discussing trained, responsible adults who could potentially protect students from harm.
For instance, in the unfortunate event of an active shooter situation, an armed teacher could potentially save lives by intervening before the police arrive. This isn't about arming every teacher, but rather having a select few, trained individuals as a line of defense.
What could be a possible approach to ensure the security of schools, without potentially putting students at risk through the presence of weapons?
