It matters because we as a society, a culture, need to learn lessons from such scandals.
Watching the Panorama show last night, the one thing in particular that became very clear was the sheer number of people who either knew, or suspected they knew about SoViles proclivities - and yet they chose not to report their suspicions, fearing they would be ridiculed, or would lose their jobs. So, a toxic combination of fear, complacency or even a kind of unthinking complicity meant that none of these suspicions were voiced - And whilst individual reports or complaints may have been dismissed, many would have prompted cause for investigation maybe.
It was also striking, on a more cultural note, that celebrity, fame, perceived glamour all served to blind and deflect criticism and suspicion.
And all of this is before we get into what might be the apparent complicity of an institution like the BBC.
And before we get too hyper -critical of the BBC - lets remind ourselves that the documentary that aired last night was one part of the BBC doing a no holds barred demolition job on another.
