In the instance of Ric Flair, there's plausible deniability by WWE that it even happened, however them settling out of court, Goldust's sexual assault allegation, and knowing Ric Flair was a raging alcoholic at the time and may have been drunk off his tits at the time... he probably did it and doesn't remember it.
One witness says he didn't see the act specifically but was probably intoxicated as others were.
Another denies it but is known for sexual harassment himself
A third was never even on the plane when it happened.
Even in the court of criminal law, that would probably have him found not guilty, but in a civil case the preponderance of the evidence probably sees him and WWE put through the wringer.
