Pictures of people being harmed (child abuse images are not porn) are not speech they are evidence of a crime.
EDIT
To make things clear.
I used the words child abuse images.
This may have been a hint that I was talking about images of actual child abuse rather than selfies taken by teenagers.
We are in a discussion about an ideal world. Let's imagine that if we were really in a position that governments were legislating about absolute freedom of speech they could also draw up some non stupid laws to protect victims of child abuse?
