User data is not disclosed to adveritsers. Please produce the documentation where I can purchase user data. All I can do is ask google to target people. I can not get info on those people from Google.

I get the desire for a smoking gun. Maybe one exists and someone else interested in the subject could share it. But at some point, people make judgement calls based off of the information made public. I would bet my original assertion is true, and that Google data is somehow being sold to the federal government, to build dossiers on it's citizens. Same with E.U. citizens.
