You are not wrong on any of your points. I was just illustrating how poor his defense is. He could have went the route I'm suggesting and I would have believed him. Sometimes after 37 yrs perceptions could be different. That all being said...he was there and he did it. He looks like a liar
She was believable. The incident is believable. I don't think he was trying to rape her. He was an inebriated young man. She went to the party and went upstairs on her own. Stuff happens at parties when you go upstairs. Guys and girls try/attempt, to get together.
Her perception and his perception could be different.
All that being said, it sure as heck happened. It makes him look like a liar.
