I'm not sure pepper spray gets to the heart of the issue. We're talking about something much more ingrained in the culture than simple predators lurking in some alley, no? Do you have any idea what could happen to a woman that pepper sprays the wrong man in some parts of the world? We're talking about a place that still has thousands of cases of bride burning each year (http://en.wikipedia.org/wiki/Bride_burning#In_India). Not sure how pepper spray is the first step here.
