Me, I've been trained, I practice weekly, and shoot at least one competitive match a month. I like to think I could returned aimed fire if a murderer was on the rampage. But maybe I am deluding myself, and I would just be another 'die in place' victim. Maybe so. But I want the chance to prove otherwise, and articles like this don't help.
Hmmm. Okay. I kinda took it as a reminder that if you’re gonna take the responsibility to carry, you need to do your utmost at keeping skill levels high. Of course, as you note, every day walkabout thinking you will respond “correctly” can quickly go to hell in a hand basket at the moment of need.
