How would someone who wasn't a celebrity have been treated by the court?
The documentary doesn't really delve into how someone who didn't have the star power and the money of a Polanski would have been treated in that jurisdiction at that time. But it seems a relevant question for properly framing how Polanski's case was handled.
If the defendant had not been rich and famous, another judge would likely have been assigned to the case. The press wouldn't have been as ravenous in following the case. Those factors would have affected the motivations of the attorneys.
What kind of sentence was typical for similar crimes at that time?
