I don't think teachers should have guns in the school, for the same reason student's shouldn't. A Teacher might get pissed off at the class and might take out the gun and use it as a threatening measure. What if the teacher accidentally pulls the trigger? it could result in a few things. The kids get scared and report the incident to the police/parents. The bullet hits someone and seriously injure someone. The bullet kills someone all these would result in the school being sued and the teacher loosing there job. It might be a protection method but it is also a risk factor.
no ok no
