While I agree that a group like this is highly ideological, it's possible, just possible, that they understand that every claim of rape that's proven to be false damages every future true claim of rape.
I tend to agree. But I think constructing the telltale indicators as an appendix to the document is a little troubling. They could have made it part of the investigative section, thus giving it more importance than having it appear to be a less important afterthought.
