I totally agree. I was going to post that a having a gun is cool and all but if you turn around and you have a gun already pointed at you you're already at a disadvantage.
I told my wife this story and I was thinking how from now on I'll probably be leaving a few people stranded but she said what about us? There was a time when my battery died at Sonics and I needed a jump. I did approach a group of people and was able to get help but next time I might not be able to if everyone is so skeptical of the stranger. I guess we do what we can though.
I think we have established that the vast majority of our society is not very defensive minded so your biggest challenge would probably be finding someone courteous enough to help.
Assuming you & your family don't look very thug-like a more tactically minded person would probably profile you as pretty low-threat.
