Ok, I agree, this whole thing is ridiculous. You should be able to take a picture of yourself, naked, and send it to whomever you want. Even if it was meant to be "pornographic".
How are you guys defining simple child nudity vs child pornography anyway? Because, frankly, I don't quite buy the whole "it's just child nudity" argument... the girls were not making an artistic statement here. What do you think they were doing?
Also, I think part of the problem in defining these girls as "children". These aren't innocent youngsters anymore. The age really should be lowered, or else, some middle stage needs to be formed, where there is still some protection, but not the full arsenal.
