The Justice Department has no right as part of an investigation of the kiddie porn industry to subpoena information Google has explicitly stated was subject to release?
For its part, the Justice Department said the data received from Google's rivals showed that the search query information did not contain "any additional personal identifying information" and that trade secrets would be protected under procedures put in place by the trial court."
Google's not at risk; the anarchist ilk on this thread fears for the pornographers.
They have no right to it under our Constitution.
Now, once you've gotten around to actually reading the article and discovered that "kiddie porn" is not involved, you can come back and apologize for spamming the thread with nonsense.
