If you're not familiar with the story of Roman Polanski, he's a highly successful Polish-French director who's won Oscars and all kinds of other awards. He was also accused of raping a 13-year-old girl more than thirty years ago, and after pleading guilty to the charges of unlawful sex with a minor, he fled the country to avoid harsh sentencing. In 2009, the U.S. asked Switzerland for his extradition when Polanski arrived in an airport there, but the Swiss government refused, making Polanski a free man who's managed to avoid punishment for his crime. If you want more information, The New York Times has a concise version of the whole thing here.
I tried to upload a YouTube video where this REALLY COOL guy talks about the whole thing, but it wouldn't work so here's the URL:
