Your statement here suggests that what is considered child porn always involves the abuse of a child. This is not the case. Many teens have been put on sex offender lists and had their lives trashed because it was found out that a girl/boy of similar age sent them a picture of themselves naked.

Also I wonder what the prevalence of fake/real violence in our society has on the demand for "snuff". You don't really need to seek out snuff films because you can easily see films that depict horrible things happening to people, completely legally.

I am not pro-child porn here, it just makes for an interesting philosophical/societal topic.
