In an ideal situation you would be with people you know, but a disaster is no such thing. A woman could easily find herself on her own and should be prepared for the possibility both mentally and as physically as possible as well as carrying something(s) to protect herself with because more than one male could be involved.
Speaking for myself there is absolutely no need to be blunt, I don't kid myself that there is no danger to women or that somehow I can always avoid it, rather I am well aware of the danger and try to prepare as best I can.
Honestly I think most women are aware of the danger and don't need it pointed out, but they could use info/tools that would help them be prepared.
