The claim was about 3 of 'em. Definitely been to some parties where I had no idea what other folks were up to ~ was even proposition once by John Dean's wife ~
But then the claim would have been "No sex took place that I'm aware of".
That's NOT what they said, they said NO SEX WHATSOEVER.
To me, it strongly implies that in the time the whore was present, she was constantly in the sight of many of the team members, who could not have possibly NOT SEEN her being raped if it had actually happened.
