I know people are well-intentioned here. However, a problem with some of the advice given is that these analyses have to be performed in about 2 seconds during total mayhem. People are screaming and running, and your heartbeat went from 60 bpm to 170 bpm instantly.
What if you're dealing with a gunman situation like the recent France attacks and you're up against people who know what they're doing? You won't know it at the time you make your analysis. You won't be equipped with enough information until afterward.
Shooters seem to be getting increasingly more sophisticated. The Batman movie attack would have been a crap shoot for me. Be honest. Who would have known what to do in that situation, without using hindsight? Whenever I imagined a movie theater attack, I never imagined what happened in that attack.
I'm not saying the solution is to give up. I just would appreciate it if people use their full logic abilities, which I know you have. Along with the solutions, let's also talk about everything that's PROBABLY going to go wrong if you get involved with a CCW.
