Re: nothing in that case that isn't perfectly legal under Swiss law
He's accused of having sex with an unconscious woman, knowing she wouldn't have consented had she been awake. It didn't "turn into rape" - that is rape in Sweden (and in the UK). It only came to light when the woman asked the police to force him to get an STD test, but that doesn't change what he did.
I am getting confused. Is this Assange we are talking about or Chris Grayling?
