Nobody's Hero beat me to it.
It also makes me a much better driver.
"Eh, so he cut me off. and I have to fall back another car length. Let's see, at my present speed of 60 mph, I'll get there a whole 275 milliseconds later."
As opposed to leaning on the horn and moving my bumper up to within 275 millimeters of his.
When younger and more agile, I would stop to help if I saw someone beside the road, especially since I carried a transmission jack and lug nut helper bar in the trunk, but nowadays, when everyone's got a cell phone except me, I tend to pass on by with a little prayer for them. Having a defensive firearm on me would make no difference.
Come to think about it, most of the time I'm not consciously aware of it. Sorta like wearing shoes. After all, when was the last time you thought, "Oh, I'm wearing shoes?"
As far as stuff in terms of "can I help you find something?" when someone's on the street looking at a map of the city (and the like) is concerned, there's no difference. I always was a helping-type personality.
In case of a struggle in the streets, I avoid that kind of thing, mainly because I didn't live to be 68 by making assumptions about who's the good guy and who's the bad guy, unless there's a woman or a kid involved. (And nowadays, I'm not physically able to help much anyhow.)
In case of a robbery in a Kwikee mart, that's really not something one could present cut-and-dried answers to and use up bandwidth to speculate upon in this thread.
In case of a mall shooter type scenario, though, I did analyze that one for myself, and, without braggadocio, I can say that I would at least deliver suppressive fire until I was no longer able to. Let's face it, I'm 68 and I might allow the young lady with the baby to get the heck under cover or outta there before I went down.
