This will also make it dangerous for students because if we give teachers guns, there's a loaded weapon in the classroom

Security guards have the right to be armed because they are trained in the field and it is easier for them to keep their weapons out of the wrong hands. Although teachers can be properly trained, it is not a good idea to give them weapons because a student could get their hands on it and cause an accident.

Arming teachers is a band-aid solution to a much deeper and more complex cultural problem. While this solution aims to ensure that schools are not soft targets, arming teachers without a proper vetting process could potentially lead to an increase in accidental gun deaths in schools, even in rare cases during which the deployment of a firearm would be useful to defend the lives of students.

I don't think intimidating children, who have little experience with managing their emotions, is the right answer. Best case scenario, they're traumatized. What is the teacher supposed to do if the child decides to charge/fight them?

yes. i also think that if teacher have guns they are also at risk of being mentally unstable and possibly use the gun themselves.
