Possibly not nuff said at all. Maybe the low conviction rate is largely due to there being no plausible case to answer in many cases.
How are reporting rate statistics gathered when by definition one side of the equation is, well, unreported? Are a self-selecting group of women from "difficult" circumstances asked by worthy (female) counsellors whether they have ever had sex which they considered with hindsight was a bad idea (from which it is an easy to claim to have been coerced)? According to some definitions of rape I have heard, if a woman gets drunk, insists a man sleep with her (impugning his manhood if he should refuse), then decides in the morning it was a bad idea, she should be able to retrospectively claim rape.
If rape is to mean anything it has to be a physical assault against one's will at the time it happens. Broadening the definition to include any encounter deemed a mistake after the event simply cheapens the idea, and gives some people an excuse to regard real rape as less serious than it really is.
