"I’m not sure I can say this more clearly: we’re not in cahoots with the NSA and there’s is no government program that Google participates in that allows the kind of access that the media originally reported. Note that I say “originally” because you’ll see that many of those original sources corrected their articles after it became clear that the PRISM slides were not accurate. Now, what does happen is that we get specific requests from the government for user data. We review each of those requests and push back when the request is overly broad or doesn’t follow the correct process. There is no free-for-all, no direct access, no indirect access, no back door, no drop box."
