Until it's your kid that gets shot by the teacher.
I specifically want to move beyond the trite statement that CCW will magically prevent this sort of occurrence. We need to understand that an active shooter scenario in a crowded and chaotic school is not the same as defending yourself against an armed mugger at bad breath ranges.
Most of the training required to qualify for CCW is all but useless in a mass shooting scenario. So, when someone bloviates about a "teacher with a CCW", I will assume the minimal amount of training and a teacher who is carrying a gun that might see a box of ammo a year, who doesn't do anything more advanced than shoot at static targets from a static position. Or, we can be a bit more specific and talk about the environment, the scenario, and the skills that will ensure a successful outcome and push for those to be incorporated into the discussion. CCW is a less than minimal spec to me.
I'm interested in people and processes, not tools.

I would only interject (and those here with LE experience or other relevant involvement can correct me) that the above would apply to cops as well, in that just because someone with a badge is on site, it doesn't mean it's a person with a badge AND qualified to handle such a situation.
In several of the training classes I have taken, some of the instructors were LE. They may have been blowing smoke up our asses, but in the "get off the X" classes, they all pointed out that we were getting better training than the average cop. I will point out that the closest training I had in any of those classes to "mass shooting" was stuff like restaurant scenarios, and they all involved clear targets (i.e., no "hostage" or "innocent bystander" blocking targets, etc.).
That's
average cop, not SWAT, etc. Many CCW holders just get a permit and a gun and nothing more than basic safety training (I suppose not even that in constitutional carry states). Many cops get some minimal training, then consider their gun an inconvenience for the remainder of their careers, while others take jobs that require extensive firearms and tactical training.
If a cop happened to be on site at a school shooting, I'm betting there's a higher likelihood that they would be the cop that gives the "don't do drugs" talk (and considers their firearm an inconvenience) than a cop with advanced training. So it could be a cop with little more training than NRA Defensive Pistol I, which many CCW holders take as a required class.
