Why non-male? I'd think a highly educated white collar white female would be able to pull it off just as well if not better. (To be honest I have trouble imagining one would want to though...sexist of me I suppose.)
Almost every woman I know has an innate fear of walking alone at night.
I'm not sure of the statistics, but my guess is that violent crime like rape happens far more to women to men.
For rape ("sexual assault"), women "win" by far (F: 91.89% M: 8.11%), but it's much less frequent than "aggravated assault" and "robbery". Also, I'm assuming that "sexual assault" doesn't include prison rape (which makes sense, since that's not something you should fear in public), but it probably includes rape by friend/acquaintance (which isn't something that you should fear in public, and wouldn't rise if living in a RV compared to a house). Allegedly, rape by stranger (in public) is a rather rare form of rape (although it still makes sense to fear it and not put yourself in situations where it's likely to happen).
Men are the majority of victims of serious crime (after removing "simple assault") (F: 40.22% M: 59.78%).

What I found interesting was a recent study that found rape has a much higher rate of PTSD occurrence than other crimes - maybe it's so uniquely traumatic (and the threat of it so terrifying) that it forces women to be more careful than men even when men are statistically much more likely to be assaulted by strangers.
Well, you don't get PTSD after murder, and I would say that rape is the next worst thing that can happen to you, so I don't think it's that surprising...
