No matter how this turns out, at least one person in this whole ordeal is utterly horrible.
Not necessarily. Even assuming that the complaint is false, she might have made a mistake or misremembered or been blackmailed or something. Or it might have happened, but just be unprovable in a court.
There are a number of grades between "rape" and "deliberately false rape allegation". Statistically speaking, it is very unlikely to be the latter. That's not to say that he definitely did it - obviously there should be a trial, with evidence and all others sorts of good things.
But maybe the evidentiary rules should be loosened somewhat? What I mean is - famously, defence crossexamination in rape cases is routinely a disgrace. Indeed, the defence case in rape trials is routinely a disgrace. Defence occasionally use a woman's sexual history against her, as evidence she was asking for it or deserved it. This is routine, as I said. Defence routinely use humiliation as a tactic. Some courts will accept the lack of prompt complaint or the lack of a "fresh complaint" against the victim (that is, if you fail to tell your friends and family about your rape before you tell the police). Many, many guilty people avoid punishment by degrading their victims - re-raping them. Maybe courts need to make the rules on cross-examination tougher? Or perhaps the solution to this problem doesn't lie in the court rules at all. Maybe legal ethics need to change, or be more firmly enforced.
Now, I'm not a lawyer, so I don't have any strong opinions either way - except insofar that I believe that it is imperative something be done. A gentleman that I knew was charged with (and convicted of) rape a few years back. It was a historic case - by which I mean the charges were quite old. Nonetheless, the cross-examination totally destroyed the witness and she killed herself. That should never happen, not even once. It is not even slightly good enough.
I hurry to point out that I have no idea how many women or men kill themselves as a result of tough cross-examination during rape cases. Does anyone know? I have looked, at least in the context of my own country.
