I'm glad you don't disagree with me concerning the perverse suggestion that teachers should be armed. Extra security at schools including the possible employment of armed guards is a different issue, and seems a less objectionable proposal on the surface for obvious reasons though I still don't agree with it. I'd rather we stop treating the symptoms and start treating the cause. There's a fairly simple equation at work here—the more guns there are in a given environment, the more often they get used, and the more often innocent people get killed through their use, both accidentally and purposefully.
I don't see you arguing for less guns in banks. Has there ever been a problem there? — Harry Hindu
Yes, the problem is more people getting killed, so you're wrong to think I wouldn't argue for that. I'd rather bank robbers take the money, leave, and then be pursued by the police (armed if necessary) than that they get involved in shootouts with armed guards and risk killing customers in the crossfire. Obviously, the more armed the guards are, the more armed the criminals will tend to be, and the more potential there is for violence. And it's not as if it's preventative. Which is why we don't have armed guards in banks in Ireland, for example, and we have less robberies and less people getting killed in robberies. So, apart from this being common sense, it works. But just research it yourself.

"Research [shows] that...the presence of defensive weapons creates a greater risk of violence
...In an environment like this, arming guards in all locations is premature. Even in locations where robberies do occur, the presence of a guard increases the likelihood of violence and injury."

"According to the FBI, the simple presence of any on-site weapon automatically increases the potential risk of violence. When a Security Guard is armed on the job, the potential threat of violence automatically increases yet again..."

The idea that the way to solve the problem of violence is to increase the means of carrying it out is completely wrong no matter how selectively you try to apply the principle. And the attitude of looking to guns as being a solution to anything rather than simply a menace we'd all be better off without is very culturally specific to the U.S. The weight of empirical evidence shows that a less armed society at every level (apart from military defence) is a safer and more secure society. There is nothing to fall back on for the gun lovers except their love for their guns and a bunch of irrational attempts at justification that fall apart even on a very basic analysis.
