Legally, Roman Polanski admitted to consensual sex with a minor (statutory rape), he did not plead guilty to forcible rape. The reason given for the plea bargain by the family is that they did not want their daughter to go through the trauma of a trial. ...No, Polanski did not legally admit to consensual sex. He admitted to a crime. Consensual sex is not a crime.
One of the great evils of our age is the increasing ability of the State to pursue criminal charges without the consent of the victim which is the very antithesis of victims’ rights. It is evil. ...
Since she has forgiven him and most likely received a large sum of money it is now no longer the interest or concern of the State. ...
I agree that the state should not pursue criminal charges against an adult
victim unless that adult victim complains. Many domestic violence advocates
have pushed for laws and processes that punish men even when the woman does
not complain. (A recent example of such punishment is here.) I disagree with that, but it has no resemblance to the Polanski case.
The Polanski victim complained, and Polanski was convicted. That ends the victim's obligation. Now it is the obligation of the state to make him serve the sentence corresponding to his conviction, and to prosecute him for being a fugitive.
