The article is primarily about rape being criminally charged. A couple of decades ago the Navy did a study that raised a tangential issue that is particularly troubling in the military -- false "allegations" of rape that are not reported to law enforcement. The study found evidence that in the military context, most "false rape" reports were not intended to be "charged" and thus formally investigated by law enforcement. For example, a woman might tell a senior officer 'confidentially' that a co-worker had raped her. The senior is now stuck --- if he reports the allegation to 'law enforcement' then he is at risk of being maligned for breaching her confidentiality, having his command bought under the microscope, etc. However, if he doesn't report it, then he may simply think that one of his subordinates is a rapist. An employee/sailor suddently gets treated like crap, gets re-assigned, etc. etc. and may never get told why. Thus, when talking about how frequently people "cry" rape, at least in the justice system there is a chance for thorough investigation. Allegations that are not made to the police -- but to bosses, co-workers, etc. might be even more problematic.

As an example, at a University I attended a young woman went to the counseling center and alleged she had been raped. She didn't want to report the incident, but was urged to -- and the report was eventually made to campus police. Instantly the school paper had headlines about a rape on campus, "are you safe?", etc. etc. Within a few weeks the police had discovered that this woman had mental problems and had reported identical rape stories at at least 3 other schools in the past. She never intended to involved law enforcement, she apparently just wanted the sympathy/reinforcement of counselors.

I don't know that the false reporting rates are, but it is an issue worth some serious study. At the same time, we should keep in mind the context in which the allegations were made.
