The woman who accused filmmaker Roman Polanski of rape in the 1970s, when she was a teenager, has revealed she didn't know that she was a victim of a sex crime at the time. Samantha Geimer claimed the director raped her during a party at Jack Nicholson's house in Los Angeles in 1977 when she was just 13 years old. Polanski pleaded guilty to having unlawful sex with a minor, but left America and fled to his home in France a day before he was due to be sentenced. He lived there for years before the scandal reared up again in 2009 when he was arrested in Switzerland and threatened with extradition to the U.S. Geimer insists the sex act was not as it has been portrayed in the media, even though she now understands exactly what Polanski did. She tells U.S. breakfast show Today, "I was 13, that makes it rape, but I didn't experience it that way... In my mind, I didn't know that was illegal, I didn't understand he could go to jail for that. I was young... "Yes it was a bad thing to do and he knows that." Geimer has previously revealed she has forgiven Polanski and still remains in touch with him through emails. She has detailed her one-night stand with the director and the controversy of her 35-year connection to him in a new book.
