Despite her story changing, or his, or any other variances here, the fact remains as thus - a court of their peers has deemed them to be innocent of the crime they were accused of.
So, thats the ruling we must accept.
Exactly in the same way as if you or I were in the dock, guilty or not, if the court says innocent, you are innocent.
The other chap has appealed and lost, so we can only assume HE is the guilty party here.
Remains to be seen if there really was a third party(s) involved or not.
What really happened that night, I doubt we will ever know.
