A bill that could allocate more than $1 billion over the next eight years to combat those who trade in child pornography has been unanimously approved by a Senate panel. "The Senate Judiciary Committee on Thursday voted to send an amended version of the Combating Child Exploitation Act, chiefly sponsored by Sen. Joe Biden (D-Del.), to the full slate of politicians for a vote. [...] An amendment adopted Thursday also adds new sections to the original bill that would rewrite existing child pornography laws. One section is designed to make it clear that live Webcam broadcasts of child abuse are illegal, which the bill's authors argue is an "open question." Another change is aimed at closing another perceived loophole, prohibiting digital alteration of an innocent image of a child so that sexually explicit activity is instead depicted."
