Until recently, no-one dared to accuse rich people of sexual assault. You'd be threatened with a multi-million pound lawsuit and have to back down (as those accusing Lord McAlpine found to their cost). Following the death of Jimmy Savile, it was suddenly OK to make accusations and the police have been openly inviting people to shop a celebrity. How many of the current accusations are genuine, how many are fantasy and how many are jumping on the compensation bandwagon remains to be seen.
