The FBI Just Asks

How can the FBI find most people so quickly? Many people think the federal agencies know everything. They don't and they don't need to most of the time: they ask for the information.

Does the FBI have a database?

It has a metadata one. The NSA's bulk telephony metadata program — narrowed by the USA FREEDOM Act in 2015 to per-selector queries — maps relationships, not sentences.^[1] A map is powerful, but it rarely closes a case alone.

The cleartext — your emails, messages, photos, files — lives in apps like Google and Apple. The FBI just needs to ask for it.

A left-to-right data flow. A person labelled You sends traffic to the apps they use — Google and Apple — which hold your cleartext. A box labelled NSA sits over those arrows, tapping the flow at scale for bulk metadata. Arrows from Google, Apple, and the NSA box all converge on a box labelled FBI on the right, which asks each holder for what it keeps.

So when you picture the government knowing everything about you, are you picturing a secret database — or the apps you already handed it all to?
