Criminologist Mark Williams-Thomas has told Daybreak that Jimmy Savile got involved in every single element of society.
He said: "He organised it in such a way that it always gave him access to children or the opportunity to offend."
Williams-Thomas however admitted that some of the charity work Savile did was geniune.
He said: "The problem was that you don't know where you draw that line in respect whether is was genuine or whether it was for an alternative motive."
