I don't know who this Jimmy Savile guy is, never heard of him until this news came out. There are reasons why someone would keep their mouth shut about certain things and for the others they'd do the opposite. If these allegations are true, it's a shame to his family and all the authorities who ignored this before. It can be possible what the victims say that some of them told someone and told them to rub it off or be quiet about it or that they don't believe whatever the victims told them that time. If no one believed them then (including someone they trust like parents or teachers, etc), of course they would think to just shut up. Remember the Pakistani/Bangladeshi descents who were charged of grooming girls for sex a few months ago, some of their victims told police and the authorities about it from the start but no one did anything then until recently. It could be possible that it happened before with the so-called Jimmy Savile victims too. Victims usually hides whatever is happening if their threatened or no one listens to them. There are things like this in the Philippines too. But anyway, this kind of news is really sickening.
