Taking this incident in isolation - I think it's reasonable to give him the benefit of the doubt, and understand that he was caught up in the emotion moment. And that, on balance of probability he was just caught up in the money and that he want doing it for sexual kicks.

I'd never even heard of him till yesterday when he suddenly became the new Harvey Weinstein.
