i am sure that information obtained by seattle shield is not shared to anyone outside of seattle borders. police departments and the FBI are not known to share information, after all. police are especially cagey about sharing with other agencies when it comes to counter-terrorism.
You have Palantir.
You still think this is "sensationalist"? I don't think so. The assumption here is that you wish to isolate this onto Seattle only. I think this is global instead. By focusing only on Seattle we lose the wider picture. Anyone remembers how people were surprised that Facebook connects offline-data to accounts? It's why they are more accurately called Spybook.
