It's tricky isn't it jno. I don't actually disagree with you particularly either, I just think it's quite difficult. Ian Hislop made some great comments regarding the BBC being attacked about Saville and pointing out that a) no one seem to KNOW, (just a lot of rumours), and b) in regards of the rumours, certainly other media organisations knew about them but chose not to report, so why is just the BBC under fire?
I don't have any enlightening view on it myself at all... It is all rather grey to me. In my work there's always a lot of blame, often at other organisations, it becomes very easy to loose sight of the fact that the perpetrator (or alleged perpetrator if you prefer), is the one to blame. Child abuse is emotional and there always seems to me to be blame for the perpetrator (obviously), and then more blame for elsewhere... I suspect it's a result of anger.
