While IAHunter's concern with respect to active shooters in today's real world is well placed there are still two problems, the first having already been discussed above, to wit, a clear 30 yard shot in a hallway full of school kids, doctors, nurses, accountants, whomever is not something any of us can expect to encounter. If you are unfortunate enough to be in an active shooter situation AND you have decided to do something about it then you are going to have to "go to the gunfire". At some point you might be able to scream out "GET DOWN" and maybe everyone complies except the shooter but we are talking about an extremely unlikely scenario. If you can get to the shooter, well, more power to you. But getting that clear, long shot is unlikely in the extreme.

The other problem we all have is our concealed carry weapons. Practicing with them at 25 or more yards tells us how inadequate most of them are absent very careful sight picture, proper breathing, perfect trigger control, etc. If you can put that together with the adrenaline pumping and an active shooter 30 yards from you down a hallway then you're likely an "operator" with all the experience that that entails. For the rest of us, taking the time to carefully aim a small handgun using all of the techniques we all know while the shooter is fixing to shoot at you and your heart is racing, well.........you get the picture.
