All over the country people are demanding armed guards at their schools yet at the same time most of them shudder at the thought the schools might allow trained teachers and administrators to carry concealed guns while they work. I suspect few realize how easy it is for anyone without a criminal record to become a "qualified" gun carrying security guard.
I have shot a lot my entire life and don't think anyone, security guards, police, or even teachers can learn how to handle guns well enough to be truly proficient and safe in a few weeks, that takes lots of practice over years, however between the two, I'd speculate able bodied teachers who are willing, will be more responsible than the average security guard who we're lucky if they have a High School diploma.
Many people who work as security guards and lots of teachers and administrators that work in schools grew up using guns, and lots have carried concealed for years. Many of them are quite proficient and have proven they can carry concealed for many years without incident. Allowing them to carry concealed is very unlikely to cause problems, would be safer and less expensive than hiring lesser qualified security guards, and might even do the job better.
In active shooter cases one of the first people who are usually shot is the armed security guard, because they pose an obvious threat to the shooter, and most of the time they shoot them without warning. Unarmed guards get shot much less often. That is why I am in favor of concealed carry.
A teacher with a concealed gun doesn't have to do anything but wait, and if the threat shows up and they think they have a good safe shot, take the shot. No one is suggesting they start firing wildly, we just want them to have the ability to shoot or deter an active shooter if doing so can be done safely.
As for all the people who can't breath when they see a gun, do you freak out every time you go past and armed guard in other places? Do you start shaking when you see a Brinks truck? Do you think you children would be safer if the schools weren't hiring armed guards?
