I would really like to live in a world where the women in my life would not have to worry about stranger intentions. We do live in a very safe city, and my daughters have over the year often come home very late at night by themselves, without any incidents. My wife often takes walks by herself after supper, without any concerns. But the local papers do have stories from time to time of assaults or worse. So the possibility of some idiot or twisted person deciding to do something nefarious is very small, but non-zero. So their approach is to stay to well-lit areas, be sure that someone knows where they are walking, and when they are expected to arrive. Other than that, we've taken no special precautions. On the other hand, I put a lot of store into listening to one's spidey sense.
