Because it takes a great deal of courage to come forward, some will be braver than others & making it public redresses the balance. This is no different to non-celebrities, this is also likely to be habitual behaviour.How does my suggestion take any side, or more importantly, take anything away from the alleged victim?
Just look at the recent scandal around abuse of young footballers, no way people would have come forward without some reassurance of being believed. Strength in numbers etc.
