Tricky part is that the sense of security isn't false... If they really know how to use the gun properly. And depending on the situation.
Statistically, a lot of people think they they're fit to use a gun safely, but it doesn't work out. Self awareness is tough.
Yeah, there was a case I just read about a couple who got a gun in case of the Ferguson riots affecting them. In their car, the woman was handling the gun and yelling about being ready for them, this distracted her husband, he clipped the car in front, which caused the gun to discharge and kill the wife.
But there's also another cause of death, which is people who shoot their guns in the air for fun, or during 4th of July / New Years Eve celebrations. Those bullets have to come down somewhere, and they do kill people. Overall, the stats of being killed by a stray bullet in the USA have been calculated as 1 in 5 million. But coincidentally, the chance of being killed in a home invasion was
also listed as a 1 in 5 million chance on other articles. It doesn't matter how responsible you are with your gun if you can die from a stray bullet from some asshat out there: you're not safer. And I'm wondering about the
narrative of the typical robber who shoots a homeowner during a burglary. The reason a burglar carries a gun is the same as you do, self defense just in case the homeowner comes at them with a gun or other weapon. Ideally, a burglar doesn't want to see any humans at all. The most likely scenario is that a homeowner confronts a burglar with a weapon, which spooks the criminal, thus causing them to fire their weapon. In those cases it comes down to a quick-draw competition, which your banking on you being faster at, no matter how well secure your firearm to prevent misuse (which also reduces the chance that you'll have it ready in a pinch btw).
