I'd love to see Google say that they not have the data requested, because they simply do not collect it from users. If Google has it, NSA will get it. One way or another. Denials and "lawsuits" against the NSA written like press releases are useless.

That's why Google and Facebook are extremely dangerous, they hold unto every piece of info to try to squeeze a few more pennies from each user. Nice and ready for NSA to get it legally: “There is no indication that this order to Verizon was unique or novel. It is very likely that business records orders like this exist for every major American telecommunication company, meaning that, if you make calls in the United States, the NSA has those records. And this has been going on for at least 7 years, and probably longer,” http://www.wired.com/threatlevel/2013/06/verizon-responds/
