the whole episode sounds rather sordid...BBC journos posing as kids online ???
I gave up years ago believing police and their shonky statistics. Quite simply-they lie through their teeth. It's all empire building. This is like that last creepy US AG Gonzeles who claimed there were half a billion kiddy porn websites...errr...how could he prove it ?..they just make up thses figures.
There was the old "50,000" figure that floated around for about ten years..."50,000 suspected terrorists" "50,000 this and that"..someone on the NY Times did a very funny article about it.
Anyway-there are going to be 500,000 civil servants out of a job soon and liable to get up to mischief so look out !!
PS: I agree ..for the BBC to allow themselves to be reduced to cheap tabloid rubbish is a disgrace.
