Yes, but that is a chance I'm willing to take 100% of the time as opposed to possibly shooting my wife, one of my kids, one of my kid's friends etc. Fortunately, I do not live alone in a war zone. If I did, I may not be so positively adamant about knowing exactly what is in the sights of my firearm. Making a positive identification of your target has been one consistent theme in the few courses I've taken for personal and home defense. What you consider a "complimentary tool at best" is considered an absolute mandatory requirement as I've been trained.
I don't believe I said anything about shooting anyone. I don't think anyone here is advocating shooting someone in the dark. I just think people often overestimate the ability of a flashlight to incapacitate someone. You're not going to subdue someone for 15 seconds while you decide what to do next. If you shine someone with a flashlight and it turns out to be a bad guy, expect that person to make the next few moments of your life miserable and act accordingly.
