Arrested, not charged, certainly not tried yet, therefore assumed innocent at present.
There doesn't need to be evidence for you to be arrested. You can be arrested in connection with a crime, and be innocent, without ever being charged... I know as I have been (not in relation to a serious crime I hasten to add) and was totally innocent and not charged.
I do get a little cross when people aren't surprised that some have been accused yet other haven't, but I DO understand why.
Creepy guys are always assumed guilty, and we're ALWAYS more disgusted by them. Look at steve tyler versus gary glitter... Gary Glitter looks a lot more 'weird' and unattractive, his crimes were gross, but he is absolutely loathed for it (rightly, probably) yet Steve Tyler has given his approval to biogs that rather proudly state his dubious and disgraceful actions in the past, with children (one specific child, who's parents signed over guardianship to ST so he could live with her, and get her pregnant numerous times - all ending in abortion) but hey ho... he's still very successful.
I'm sad that Rolf Harris is in the frame, I hope he's innocent, or rather I hope that the police have sufficent evidence against him to validate his arrest (if that makes sense). Although I understand the lack of surprise regarding Jim Davidson, I worked with him when I was 18 for 8 months, and though he was a letch, and he was 'cheeky' (cheesy, vom inducing cheeky) and rude, a masogynist, a tragic figure, and although he had women QUEUING at his dressing room each night to get what he referred to as his "pre-show BJ" I have to say, after spending most evenings with him and his followers, he never to my knowledge preyed on under age girls... in fact, he wasn't fussy, there was one particular 'duo' a woman and her mother... the daughter was 28. So although I understand, there's an element of doubt for me. Again, he's not been tried, therefore must be assumed to be innocent, even if we wouldn't be surprised once found guilty.
I strongly believe that everyone should remain anonymous until verdict, because of the utter devastation caused by public naming the accused if they are then found innocent... because that kind of mud sticks, and I don't believe the means justifies the end.
