"Jury believed that at the time of sex she was incapable of consent."
There is a presumption, but no evidence, that this was the grounds for conviction.
An alternative is that a drunk woman, having sex in a hotel room with a man a lot stronger than she who she has had some conversation with, is surprised and horrified when the door of a locked hotel room opens whilst she is naked. In comes another man much stronger than she, a total stranger to her, who she has neither met nor invited to watch her naked, having sex.
Instead of turning round and telling the stranger to fuck off, the man she is with stops having sex with her and greets the stranger in such a way that it's clear they are friends and that he's not surprised to see the stranger, in fact, he invited him. He is on the stranger's side, not hers.
The stranger doesn't back out apologising, he walks forward and takes out his penis. He has clearly come here with the intent to have sex with whichever woman was on the bed, and the other man isn't about to step in.
Do you think she has any kind of freedom to say no, seenem?
