Hence my last point. Do you know how rare drop misfires are? Pistols produced since the 80's are equipped with not one, not two, but three drop safeties. ND's are becoming less and less common. Though I would argue that ND's are not a valid argument for common carrying. Mostly because ND's do not occur during the act of carrying itself.
The fantasy of some guy's pistol going off in his pants during a worship service is about as fanciful as a parking break spontaneously engaging on the highway or a blender turning on without being plugged in.
The two other scenarios are different in nature. An innocent person getting caught in the crossfire is exceedingly rare for multiple reasons mostly having to do with the mechanics of a shootout. I won't go into the gory details as to why unless you really want me to, but most of them have to do with the distance, mechanics, ballistics, and human behavior.
Now, it would be more of a factor if we're talking force on force (ie platoon on platoon) combat. But that isn't a scenario we are discussing outside the state of Montana (I make joke, hahaha).
The third and final con- the cowboy vigilante type- is a very real possibility. Some people do get the wrong idea of what it means to be an armed citizen despite parental training and 2A culture teaching them otherwise. It's inevitable.
But those people are rare in proportion to the percentage of drivers involved in road rage incidences or the number of people using prescription drugs who abuse them. Should we ban the common use of cars? Should we ban life-saving drugs? How about alcohol?
We don't, because we live in an imperfect world where where deadly trade offs exist and new ones present themselves with virtually every technological advancement. There are times when prudence calls for laws that limit or ban certain things, but prudence is not the same as perfection or sterility.
If I was largely correct in my approximation of your standard, then you have to admit it's a fairly weak standard to go by. One that reeks of the subjectivism you so ably demolished in previous misc forum discussion. It takes the very real gun and warps it into something that only exists in film.
How fair is it to take so weak a standard and paternalistically (or I suppose maternalistically) deploy it on an object people use to defend themselves and their families on a day to day basis?
Pretty much spot on. However, I have been around one person who was irresponsible and dropped a gun which DID go off and could have struck another person. So I know guns can be dangerous in the hands of irresponsible people.
It's not ONLY that, though. I also am leery of people who might be very knowledgeable about guns and gun safety, and might THINK they are helping stop crime but actually harm a bystander or completely innocent person. I don't think the guy who shot Trayvon Martin thought to himself "Let me shoot a black kid," I think he thought "That kid just broke into someone's house and is getting away."
I am leery of people being overzealous in stopping crime.
Not that I think that EVERYONE who carries a gun would be quick on the draw, but some people would be.
