Even if sending in a 35mm roll of film to the lab with a pic of your toddler in the tub, there was a chance that would not be printed. I don't recall any lawsuits against Kodak for not developing a photo now and then to maintain overall decency.
No, but I seem to remember that the pictures individual photoshops were turning over to police as "child porn" was getting perilously close to an isolated kid in the bathtup among a bunch of family type photos.
