A link to a very interesting article is cited below. First off, Soon Yi was never adopted by Woody Allen. She was adopted by Mia Farrow and her husband by the name of Previn, so technically Soon Yi was the daughter of Allen's long time girlfriend. Soon Yi was 21 when Farrow discovered the affair with Allen. Yes, I think it's creepy, but who am I to say what's creepy and what isn't creepy?
Second, Allen and Soon Yi are married, still together, and raising two adopted daughters.
Third, the initial accusations were made during a bitter custody battle. Allen passed a lie detector test, and Farrow refused to take one. Two of Farrow's employees later said that Dylan was never out of their sight on the day that the incident was supposed to have happened. Some of Farrow's employees also said that the little girl was coached by Farrow.
Fourth, Mia Farrow has not mentioned the facts that she was a character witness for Roman Polanski, (who admitted having sex with a 13-year old girl), and that her brother has recently been imprisoned for child molesting.
There are tons of other facts in the article that could make one think that the only child abuse committed in this case was by Farrow in brainwashing a child into believing that she was indeed molested just to get back at Allen.
