After the events of Columbine, and several other school shootings, why are teachers still not armed?

Great question, How I see it is most all of the states are short on teachers now to teach. Just think about if we would arm teachers you would have to train them. And all new teachers would need trained also. So that could take years and years. And the big thing about it is some teacher now cant do the job they have in the first place TO TEACH. so lets arm them too..Alot more thinking has to go in that idea..

what are you nuts? you want a teacher to walk around carrying a gun? ok hitler!
Reply:Just what we need, more people with guns who are not qualified to use them. There would be a dozen or more unnecessarily dead kids if teachers had guns. We already have too many cops with guns that shouldn't have them and we read about bad shootings all the time.
Reply:I know that the school shootings are bad, but I think that teachers have enough to worry about without them having to worry about some getting their gun and doing harm to others. I just dont think that this would accomplish anything.
Reply:Exactly like the lady above me said.Any kid can just beat the crap outta the teacher and take thier gun. Not only that, but teachers are normal human beings also. Whos to say that any one of them wouldnt have a bad day and flip out themselves. Just not a smart idea.
Reply:most teachers don't want to be armed but would like for school security to be tighter...I really don't have a problem with fences, metal detectors and id badges with barcodes...but not guns for teachers
