also isn't part of the point with child rape material that a child has been/is being abused to make those images?
^^That!^^
Like the Extreme Porn legislation, which is more concerned with people looking at "extreme" stuff, than to find out whether the people who took part in the photos/videos were consenting adults. Why this refusal to tackle the crime first and foremost? These laws are purely cosmetic.
Child abuse is crime. Fight that, not the people who may want to look at the images. Like the porn ban, this government (and the previous one who passed Section 63), are more concerned with thought crime, than with real crime.
