It goes without saying civil and criminal child abuse, neglect, and abondonment cases are as difficult as any to stomach. But there are famous case of parents with "bathtub" framed photos of their kids on their hallway walls and grandfathers with pictures of their grandchilds running through sprinklers, and as you might imagine they were painted as the devil incarnate.
Our law clinic was very aware the issues of text messaging even then, 2006. At the time we used the Socratic method to debate the logic and human aspects of charging the young children guilty of originating "sext messages" of themselves. My position was always that such a law would chill the indemnity a victim needs to come forward.
One of the major issues is that many of these crimes are under the strict liability [2] standard meaning if the pictures exist, the defendant is guilty, notwithstanding their intent.
