They don't do that either.

Google's value in tracking is in providing services to users with the tracked data and (in the ads arm) linking advertisements to potential interested users (which is a system they broker internally).

They don't hand data to third-parties; third-parties hand data to Google, and Google might kick out answers to questions, but it does not kick out answers to questions like "Hey, is this person a terrorist?" There's no program for that. Hell, Google doesn't even kick out answers to questions like "Would Bob like to buy my shoes," the entire ad network is architected to minimize the ways an advertiser could glean the identity of a specific user who saw their ad.
