Active Shooter, dark, ballistics helmet and/or body armor

His advantages also have disadvantages. Unless you have trained to do it, firing accurately while masked is difficult. Also, if you are shooting in the dark while wearing a mask, you can't see shit.
I have straight eight night sights on my .45 and 14 rounds on tap. I have been exposed to CS gas multiple times, and I know that I can function in it. Your best bet, in that situation, IMHO, is to flank the shooter, if possible, while making well-aimed hits, and head shots if you can. Of course, this will apply to almost any active shooter situation.
Use the fact that he doesn't see you coming, and blindside the f*cker with a serious weapon. The rest is just details.

Preparing for this eventuality is a waste of effort. No sense to hedge your bets. Your best case for survival is escape, or to use a human shield.

If you could tag the shooter, he might just end himself--when Jeanne Assam took on the New Life Church shooter here in the Springs, she hit him once, then he shot himself. I can't speak for the truth of it, but I've heard that shooters often kill themselves rather than be taken alive, once they've been shot and injured.

I don't think it is a waste of effort, if it results in an enhancement of skills and capability. Being trained and equipped to take on an active shooter isn't going to hurt you if you run into a more common and "mundane" threat such as an armed robber, or home invader. Besides which, you may find yourself without a good escape route. Anybody sick enough to do something like this is twisted enough to put chains and padlocks on the emergency exit doors prior to entering the theater. And at midnight, it's entirely likely that nobody would notice him doing so. Or, you may be at the theater with your family, and judge that their best chance of escape/survival is for you to attack the active shooter.

I gotta work on face/head shots more often..........

Oh.......and since he did wait for police and surrender, EDT pointed something out: Colorado does technically have the death penalty, but due to their judges, it rarely ever gets used.

So I think there should be a change of venue........to Texas. The state with a death penalty express lane.

I carry , a 4" 357 or 44 mag Taurus tracker but confusion screaming gas , then try to flank him in the mess , yup I would go for it , the odds are not in my favor, but given it happened here I would not be alone, much like some more conservative areas of our country.
This gives me something to practice though, setting it up could be interisting.

Multiple CCW holders responding in an active shooting event is an idea that scares the crap out of me. Not because of danger to bystanders, but for the potential of target mis-identification. Granted, in the theater shooting, I don't think that the shooter would be mistaken for a CCW holder, but if the goblin was more like the AZ guy and just had a pistol, the potential for mistaking each other for additional accomplices would be a lot higher. The odds of multiple active shooters has got to be a lot lower than the odds of multiple CCW responders, but it isn't unheard of.

It's a reason to try to look professional while carryin, rather than looking like HS in his wedding pic...

Tactically, it depends on position - and I wonder how many of those killed were trampled - he would had to have stayed in the aisles, to avoid stumbling.

If he was up-slope from you, go for the head, if down, go for the legs, but I think I would be more comfortable either going for shots, which will hit the floor, and count on JHP's not ricocheting much, or shoot in the body armor, to try to get him to shift/go down to be able to place a more certain shot.

Why are there never calls about reviewing processes to flag the mentally ill after this?
