I don't think jail without a day in court is the way to go, no. That would be ridiculous. I am surprised at the grounds on which this re-trial was granted though.
The way things have gone, I do feel they might as well change the definition of rape if there is no way in hell most accusations can be proven. So why bother giving the victim the impression that the law is there to protect her. Just say she asked for it. That's literally all you need to do. There will always be doubt that the woman is telling the truth, and all the defendant has to do is convince the jury that their doubt is reasonable and, boom, acquittal. She asked me to go harder, she liked it rough, she had sex with me before, she had sex with someone else before, she had sex with someone after, she clearly likes sex, what proof is there that she didn't like it, have capacity to ask for it and ask for it on this occasion? You can invent whatever narrative you like.
I know men can be raped too, but I've only referred to women above because, let's face it, there is a whole lot moe sympathy for male rape victims and there is not a culture of doubting their claims.
And I say none of this as a legal expert or someone wanting a lively pub debate where we all play devil's advocate, I say this as someone who has been raped, and know that the men who raped me knew what they were doing, and knew they would never be punished for it, because that's how tnings are.
