Google Removes Child Porn Post & Reports To FBI

Child Pornography Complaint at Chilling Effects illustrates how Google received a complaint of child pornography in its Google Groups service, causing the company to remove the post and report the incident to the FBI. Google reporting to the FBI? As Chilling Effects explains, it's something electronic service providers are apparently required to do. Other search engines have probably taken similar actions, but Google is still unique to my knowledge in publishing its takedown actions to Chilling Effects.
