U.S. attorney general calls for 'reasonable' data retention
The failure of some Internet service providers to retain user logs for a "reasonable amount of time" is hampering investigations into gruesome online sex crimes, U.S. Attorney General Alberto Gonzales has said. The Justice Department quietly shopped around the idea of legally required data retention. In a move that may have led to broader interest inside the United States, the European Parliament last December approved such a requirement for Internet, telephone and voice over Internet Protocol (VoIP) providers. Congress is now considering similar policy changes.
