1. I didn't say a civilian gunfight was as likely as the zombie apocalypse. I said, for most of us, a protracted gunfight was about equally likely as a zombified cataclysm. An armed confrontation, unfortunately, is measurably more likely.
If by
protracted, you meant a gunfight over an extended period of time (reference to additional magazines), I still don't agree that it's about as likely as having to deal with zombies. I understand your hyperbole, of course, but I think it's over-dramatic. While extremely unlikely, an extended gunfight isn't at all
impossible. On the other hand, flesh-eating, tireless, man-hunting zombies are impossible (though some will disagree).
2. Good points about some of the costs of a BUG versus a vest; social costs count, too. But the old saw "two is one..." is a pretty flimsy reed. After all, if the premise is that guns are so likely to fail that one automatically subtracts one from the total, why isn't the BUG also a zero?
Probably because of a point I'll make later, but for the time being, suffice it to say that I believe, for most people, carrying a gun is nothing more than a means to the end of social anxiety (I don't mean this as an insult). If one is none, and two is also none, carrying a gun doesn't solve their problem.
Now, it's possible that the costs of carrying a BUG are so low that its virtually-guaranteed uselessness is not a problem. Hey, a free solution to a .0000001% chance problem is still free. And that may be the case for you. But I think it's hard to rationally justify a regular old civilian feeling a need for a BUG, or a fear-based desire to carry three mags.
Actually, I don't carry any firearm whatsoever, much less a BUG. I suppose I could throw loaded magazines at an attacker, but I don't carry any of those either. I just meant that I can understand the mindset of someone willing to carry a BUG. However, even if I did carry (and I plan to someday, because I'm working toward a career in law enforcement), I probably won't keep a BUG on my person, unless required to because of my employment, or something along those lines.
I do agree with you that based on the circumstances and guidelines applicable for civilian SD, additional magazines may be unnecessary. That being said, the answer may very well be as simple as someone feeling that they don't
need to justify carrying an extra magazine or two, just as they don't
need to justify carrying a primary firearm in the first place.
As I said earlier, my personal opinion is that carrying a weapon is more of a peace-of-mind issue than actually maintaining a tool set on one's person at all times. Many people may disagree, but I'm confident that I can debate the point well enough to convince someone in one of the three following points (provided I'm debating a person who understands and appreciates logic - many people nowadays do not):
1) To simply stop carrying altogether,
2) To concede it's [carrying a firearm] primary purpose is to put them at ease in social situations, or
3) To begin carrying large backpacks full of "tools" they'll probably never, ever use. Just like they already do, with the firearm.
Is it that cut and dry? No, there are exceptions to every rule (except zombies. It won't happen
).
