That's not true at all.
What should be done then? Automatic guilty verdict and just punish then and there before a case is even brought before a court?
Yet another good reason why people would settle whether guilty or innocent, and especially to do so before anything became public.
What should or shouldn't be done is irrelevant to how an individual decides to respond to this news. Our justice system is fucked when it comes to rape. We can't change that.
But we can acknowledge that guilt/innocence in the court of law can be irrelevant by the lack of evidence in these cases, and we can believe women when they risk speaking up about powerful men, instead of siding with these powerful men, essentially calling the women liars. Why the hell do you think women don't speak up to begin with? Because when they do, they are slandered and dismissed by those looking to defend the man.
Ask Christine Ford how well speaking up worked out for her, and how much it actually changed things.
