That's a point of view. A cynical one. But then, it seems to me that, under any Common Law system, truth comes a very poor second to a cogent and convincing argument.

However, I'm aware of many cases where the Crown Prosecution Service has not prosecuted because they felt they could not prove the charges, and of other instancces where the courts have dismissed the case because the prosecution failed to convince the judge/jury of the accused's guilt.

This thread reminds me, I still haven't heard back from our new Government re the censorship of the Internet in Australia. They're proposing all sorts of things, whereby any PC which could concievably be viewed by kids won't be able to view 'adult' sites.
I wonder if they'll consult China on how to do this ...
