True, but when there were complaints, the final word would have been that nobody dared publish the report of an aggrieved individual who, ignored by the police and a self-preserving coterie in the entertainment business, told anyone. That was where defamation law came into it.
Nobody dared publish information they did have, in any programme, until Saville was dead and could not sue.Once they could, and did, the floodgates opened and the police were kicked into action. Nobody could sue then because you can't sue on the basis only that someone has been arrested
