Somewhere on the Internet there is an image of a child. Perhaps this child is naked, perhaps this child is wearing clothing that, if worn by a post-pubescent, would be sexually appealing to you? Perhaps this child is being abused. This image might even be real, rather than one of the ever growing number of artificial representations that are on the internet in the form of computer generated models, hand drawn images, or similar.
This image could be illegal. Artificial or not this image will effectively end your life, and why not? An owner of such material is effectively supporting the abuse depicted, so why not monitor the people using the Internet to catch these supporters of this most heinous of crimes?
But where do we stop?
What if I have images of a terrorist attack, am I supporting terrorism? What about my small collection of colour footage from Nazi Germany, should I be prosecuted for war crimes simply because I  have videos of burning 'tommy-cookers' or archive footage from the World War two death camps? Has a crime actually been commited?

  In my opinion the Internet is the realm of thought, it is a place of the human mind, and like it or not no crime has actually been comitted in owning images, no matter their content, just like no crime has been comitted in thinking 'people from X race are inferior to Y'. We should not confuse reality with fantasy, we should concentrate on the creator and purpetrator, not the passive viewer who keeps their darkest longings solely within their own mind, no matter how warped that mind may be.
  Some say that Internet censorship is being proposed to combat a real evil, I say they are trying to apply their morality to our mind, which can ultimately only lead to psychotic pandemic.
