"The fourth charge accused Assange of having sex with a second woman, Miss W, on 17 August without a condom while she was asleep at her Stockholm home" Does that mean sex with a second woman while "she" as in "the first woman" was asleep, or while "she" as in "the second woman" was asleep and apparently unaware of what was going on? Also curious to the sort of evidence to prove these accusations; video/audio recording?
