The other problem with arming teachers is that it assumes that the teachers themselves would want to be armed. From experience, I assure you that many would not. In a good number cases, it's misguided hoplophobia, but in other cases, it's simply a matter of preference. I am as big a supporter of the 2A as you will find, but I wouldn't carry at school, even if I could. Let me tell you why:
1. As mentioned in my previous post, it's about as horrible a tactical situation as there is. Look at the police response to school shootings the last few years, and you will notice that they don't just charge in and start hunting for bad guys. Partially this is because of common sense, but partially this is because there are a lot of innocent bystanders in the building.
2. If I were to carry, and had to use my gun to repel a shooter, god help me if I hit a kid on accident. Not only would that be the worst possible thing for me personally, but it would crush me financially, permanently end my career, and would do no good in general. I know, some of you are thinking "Thats a risk I would take", and philosophically I agree that if I were to shoot an invader and hit a kid, thats acceptable because I theoretically saved many more lives. The problem with that is that I only theoretically saved many more lives, and if it were your kid that was the sacrifical lamb, so to speak, would you really care about the lives of the others? My guess is "no".
3. Frankly, I don't want the responsibility. I love my kids and would take a bullet for any of them, but I don't want to be in a position where I might hurt a kid, ever. The problem, as I see it, is that when people talk about arming teachers, they seem to ignore the fact that you are placing an enormous amount of responsibility above and beyond the tenets of "self-defense" on that person.
4. Tool-wise, a pistol is a bad idea in this situation anyway. Even if I would carry and even if I did want the responsibility, I wouldn't want to try and defend myself and the students with a pistol. Not in that environment. A school is not my house, and engagements will be more likely to be at longer than normal distances. I can't shoot a pistol well at 50 yards under stress, but I know for a fact I can shoot a rifle well at longer distances than that under stress, mostly because I have done so. In the extremely unlikely event that teachers are allowed to be armed, I highly doubt that they will be allowed to haul rifles around.
5. I again go back to time and money. I necessarily put in at least 60 hours a week during the school year, and some weeks even more. I'm not complaining about that as much as I am pointing out that when the school year is in session, I am busy and simply don't have time for a lot of other stuff. While I also won't complain about us poor teachers being underpaid, I will say that I don't make enough money teaching to justify spending money to go to Thunder Ranch or something. It is unlikely to the highest level of unlikeliness that the district is going to spend the money to send teachers off to train them in the art of armed combat.
6. Finally, there are parents. Like it or not, those are not our kids we are teaching, and as a result, we have a responsibility to the parents. My guess is that the majority of parents DO NOT want their kids' teachers to walk around packing heat. Even though a good deal of this is simple hoplophobia, it still remains a fact. You can't believe some of the stupid, petty and insane things some parents will complain about. I can only imagine the outcry if I were to carry a gun. I once was threatened physically (over the phone) by a parent because I sent a kid to the office for vandalism, three times. When the parent came in, and saw that I am a big, imposing dude and not a milquetoast, the threats went away, but the complaints about why I was picking on thier kid persisted. For hours. At one point, I honestly was about to lose my temper and just start screaming, but I opted to just refer them to the principal, which was the better strategy. My point in telling you that is to simply this: Those are other peoples kids. We may not agree with how they raise them, but it is not our place to take major decisions out of the hands of parents, and exposure to guns is a major decision. I disagree with teaching kids that firearms are bad, but it is not my place to counter a parents on the morals and ethics they want their kids to learn, anymore than it is my place to tell a kid that he or she should always vote republican, be a christian or drink mountain dew. My job is to teach them a particular subject as best as I can, help them explore different moral and ethical values via community service projects, clubs and assignments, and to lead by example.
