I understand what you are sayingand the question you are asking but . . . .

Put yourself in a similar position of being totally innocent (forget Harris for now) and facing a public accusation and a possible trial. How would you defend yourself if you did have the time, were in the place and had the opportunity but you really did do nothing? You're facing a serious allegation, you've been publicly identified and all you can say is that you "didn't do it" so what else can you do?

What if you had been abused decades ago and at last saw the opportunity to get justice for the crimes committed against you?  Would you be happy for your word to be ignored? 

In all these cases it has not been a matter of a single individual making a claim that hasn't been corroborated in one way or another - there has been either backup from other witnesses/victims, evidence of early complaints being ignored or evidence of active cover-up activity.

It was the acceptance that no action should be taken or investigation carried out on the word of an individual that allowed Jimmy Saville and others of his ilk to get away with their perversions for so long.
