Roman Polanski was allowed to plea down to a far, far less monstrous charge than that which fit the crime he actually committed; as previously mentioned, he gave a 13-year-old girl champagne, plied her for sex and--when she refused--he drugged her, raped her, and sodomized her. When he heard a rumor that the judge was considering going back on the plea arrangement, he fled the country, living in exile in a nation that specifically does not extradite for sex crimes (France... go figure). He frequently made travel plans, then canceled them when he found out the US was going to try to make a grab for him once he set foot off of French soil.
It's not as if we simply got bored, and went after a man who's been taking it easy for 30+ years. Polanski got careless with his travel arrangements, we heard about where he was going, we made the arrangements to have him collected, and--this time--he actually showed up. Go figure that the guy would relax a teensy-weensy bit after three decades, right?
I'm not going to go all emo-ape about how he "ought to burn in Hell," mainly because (a) I don't believe in Hell, and (b) if Hell is real, he will go there--or not--with no input or exercise of authority from me taken into account. What he OUGHT to do, now, is rot in prison for a while. It's not as if he's been living in a hole in someone's cellar for the past 30 years--and, just maybe, he ought to have been. He's been growing in fame, making friends, and living the high-society life.
Did he repeat his crime? I've no idea. I don't know if he was ever accused; I don't know the actual, non-stereotype-colored likelihood of a celebrity in France getting away with doing something like this, or what kind of outcry there would likely be. I have no clue; the only thing I know is that, speaking solely on terms of statistics, an individual who commits a crime such as this is more likely than not to repeat the offense, and he got away with it once.
(Until now, that is...)
