That summary is misleading and, I feel, wrong. It's not accurate to state that he was "a victim of child pornography," the complaint in this case was against him by the parent of another minor that he was "sexting" with.
That doesn't excuse the police behavior here, but you're attempting to paint a picture where the victims in these cases are outright ignored in a misguided search for justice. You're twisting this case[1] to fit your narrative, I think.
Further, he sued the government and won. The courts made it perfectly clear, the lower courts and police were absolutely in violation of this teens rights when it granted and executed this search warrant. So egregiously that "qualified immunity" doesn't even apply to the officers estate.
I wasn't going to address this, but..
> Therefore CP laws very quickly stopped being about protecting the children and more about punishing the pedophiles.
Pedophiles create a market through demand. Often it is also pedophiles that are on the supply side of this market, but not always. Merely participating in the demand side implicates you in these crimes against children as you are suborning their abuse. One could say that our system merely recognizes this fact.
