I was participating in one of those threads discussing an instance where a person incompetently reholsting their firearm lead to a negligent discharge. In this case the person in question was using a leather holster and a flimsy part of it bent in under the trigger. The discussion started off well with everybody pointing out that there are no medals for being the fastest person to reholster. But then somebody had to saying, “That’s why I carry a gun with a manual safety.”
That mindset is incredibly stupid. First, it’s an admission that the person views themselves as too incompetent to look at what they’re doing when they reholster their firearm. Second, they assume that they are only going to be incompetent in a very specific way and not incompetent in other ways.
I’ve come to label this mindset as the somewhat incompetent fallacy. It’s the idea that somebody who expresses themselves as being incompetent believes that their incompetence only happens under very specific circumstances. In the case above the somewhat incompetent fallacy applies because the person admits that they’re too careless to watch what they’re doing when reholstering a firearm but not so careless as to ever forget to engage the manual safety. They believe their incompetence only happens when they’re going through the motions of reholstering.
From extensive observations I’ve come to the conclusion that people who act careless with weapons tend to act careless in general. Therefore the belief that a manual safety will protect against a negligent discharge is, in my opinion, stupid because somebody who is so careless that they won’t watch what they’re doing when reholstering is almost certainly too careless to ensure they reengage the manual safety every time they reholster their weapon.
