Different situation. The Savile allegations come with supporting statements from different alleged victims over decades all with similar stories to tell, indicating a specific pattern of behaviour, and even his contemporaries suspected that he was doing something he shouldn't have been doing. The allegations against Michael Jackson have come with no supporting evidence to indicate any wrongdoing
The pattern of behaviour in MJ could be said to be inviting young boys over to his house, spending the night, sleeping in one bed, drinking 'Jesus juice' and molesting them.
His former employees are now saying they him having showers and naked pool parties with the boys.
How is that different to the Saville case?
