Perhaps total chaos would be better?
No.
Polanski isn't likely to do this again. If the victim doesn't want to punish him for his crimes against her, I don't see why we should.
Polanski is a pedophile. He is all but guaranteed to commit the same crime again. I wouldn't be so sure that he hasn't, and just got away with it. Pedophilia is an illness, and the problem with pedophiles is that once they get a taste of it, they almost always do it again.
