The UK needs to listen
Luke, Graham,
Being a paedophile is not a crime. Clearly you don't understanding the meaning of the term.
Now, as regards this decision....
Nobody should be convicted for merely viewing (known as "making," under UK law) or possessing images. The people responsible for abuse - if the image is actually abusive and not just a picture of a kid in the bath - are the people who produce the images, not the people who view.
The UK does not realise this.
The old argument which states, "The images are only produced because John Smith wants to view them" are not true when describing people who view child pornography *without purchase*. It's like saying that musicians create music for people to download for free from file sharing networks.
If the UK government imposed tougher penalties for production, the people who ARE abusing children would be imprisoned.
At the moment, you're more likely to go to jail for a conviction of "making" child pornography, than you are for a conviction of child molestation.
