I am NOT saying hard evidence doesn't exist but it sure would have been great if one of the women or all of them would have taken this to court . Settling out of court allows this type of behavior to be waved away as it being just a money scam.
If one of the women would take it to court then real justice might be done. This will always be under a cloud because he was not found guilty in a court of law only in the court of opinion. 
It takes a lot of courage to go to court and is really emotionally devastating but rape victims do it.
If more women did it, like the Bill Cosby victims have done by taking it to court then justice can be done for all.
