TechDirt is reporting that the ACLU has stepped in on behalf of several teens facing the threat of child pornography charges in Pennsylvania for sharing nude pics of themselves. Unfortunately for a girl in New Jersey, she is facing much more than just a threat, as she was arrested yesterday for posting almost 30 explicit pictures of herself on MySpace for her boyfriend to see. "...the ACLU has sued the prosecutor on the girls' behalf, saying he shouldn't have threatened them with baseless charges — which haven't yet been filed — if they wouldn't agree to probation and a counseling program. The prosecutor says he was being 'proactive' in offering them a choice, but the ACLU says he shouldn't be using 'heavy artillery' to make the threats. As its attorney points out, teaching kids that this sort of behavior can bring all sorts of unwanted and unforeseen ramifications is a good idea, but threatening them with child-porn charges isn't the best way to do it."
