Ah right. Didn't know that indecent was worse than that.
Is it? Does anyone actually know what "indecent" was decided to mean in that particular case? It's a word that doesn't have any objective meaning and it's an easy mistake to assume that the meaning being used is whatever subjective meaning you apply. For example, a woman being out in public without a man to chaperone her is considered indecent in some places. It's possible that the images he had were just normal pictures of children and it was decided that it was indecent for someone to have pictures of children other than their own relatives. "indecent" can mean anything. Without a specfic definition in a specific context, it's a meaningless word.
