I had read at the time that it was considered pretty questionable and people weren’t sure it would stand up to appeal. You get accused of a crime, and there isn’t much evidence that you did it, but in the trial a bunch of people say that you did the same thing to them, but also without evidence and they didn’t report the crime.
The guy is obviously guilty and has gotten away with it because he was rich and powerful, but I can see how the scenario could be abused to convict someone who’s Innocent.
