Is Wikileaks a criminal conspiracy or a political discussion? That seems to be at the heart of a debate over whether Twitter should be forced to give over records on some people involved in Wikileaks to the US government. Government investigators want the records of when the three people in question logged on to Twitter, who they contacted via private message, and what they said. With that information, the investigators would have a more complete picture of where these people were and what they were doing. That request has been challenged in court in Alexandria, Virginia, according to documents unsealed yesterday, on grounds that it violates free speech.
