A federal judge on Monday temporarily blocked a prosecutor from filing child pornography charges against three northeastern Pennsylvania teenagers who appeared in racy photos that turned up on classmates’ cell phones. […] Munley’s decision to grant the teens a temporary restraining order prevents Skumanick from filing charges while the lawsuit proceeds. The girls “make a reasonable argument that the images presented to the court do not appear to qualify in any way as depictions of prohibited sexual acts. Even if they were such depictions, the plaintiffs’ argument that (they) were not involved in disseminating the images is also a reasonable one,” Munley wrote.
