People own their bodies. Taking pictures of yourself, if you're a child, isn't child porn any more than touching yourself is molestation/assault.
Children don't need to be hit with "strict liability".
A person trying to frame someone else of a serious crime commits a serious offense, yes.
But that's a logically separate concept from the production or possession of child pornography, which that person must not be regarded as committing if the images are of him or herself.
The idiotic law potentially victimizes victims. A perpetrator can threaten the child into denying the existence of the perpetrator, and into falsely admitting to having taken pictures him or herself. It's exactly like taking the victims of human trafficking and charging them with prostitution, because the existence and whereabouts of the traffickers couldn't be established.
Whoever came up with this nonsense was blinded by their Bible Belt morality into not seeing the unintended consequences.
