The US DoJ has agreed to a much narrower focus for the US administration in terms of forcing Google to comply with orders to hand over user information as evidence to back up child porn legislation. The requests in question will be reduced in scope.
Since Google stood its ground and refused to hand over user data on a random sample of millions of searches and web addresses, the DoJ has now culled its request to around 5,000 search terms and 50,000 web addresses.
As well as voicing privacy concerns, Google has commercial concerns of its own, and did not relish the demands to hand over any information on its search technology.
