How is this a defense? How many people who commit sexual assault or rape invite witnesses with them?How many victims know to invite a witness with them? this shit usually happens in private...
It's not just a lack of a witness to the crime, but to any single aspect of the story. She has yet to have anyone even put them at a party together, let alone in a bedroom. This is on top of having nothing else to show besides dumb stuff from decades later that is not proof of a crime. If you have literally no proof, it's he-said, she-said, and it needs to default to innocent in that case. That will really suck for victims with no evidence, but we cannot go on the word of one person without a shred of evidence.
What about the character witnesses of his old drinking buddies tho
