Yes. The US Supreme Court has addressed the matter saying, in effect, "We can't define porn, per se, but we know it when we see it". Though it is obvious to most people that something is child porn, a significant (statistically more than 10% but a percentage that is unknown) per centage of us would disagree. Hence, there are sites that 'poses' little girls (and boys too) up to pre-teen years in various states of skin (no nude) in provocative ways. And...it's legal. Society can crack down, but at what cost...Benjamin Franklin's quote about the balance of security and freedom has historically been correct. The more security, even for children who don't know what happening to them while they're in front of the camera, the less freedom. Some would argue, less freedom equates to less creativity and a chilling effect on art, including movies, paintings, sculptures and photography not intended to be provacative. I feel like such a blowhard and I don't intend to be, but I guess I have that freedom too...
