Federal prosecutors just dropped charges against a child pornography suspect rather than reveal the source code for their Tor exploit. Of the 200 cases they're prosecuting nationwide, this is only the second one where the FBI has asked that the case be dismissed. "Disclosure is not currently an option," federal prosecutors wrote in a court ruling Friday. The Department of Justice is still prosecuting 135 different people believed to have accessed an illegal child pornography web site. Before shutting it down, the FBI seized the site and operated it themselves for 13 more days, which allowed them to deploy malware to expose the users' real IP addresses.
