Proof? You want proof for something that has to be true? Phones, accounts, habits, preferences, property, births, deaths. Everything recorded, aggregated. Everything. Do you doubt this? Everyone's entire lifestream is archived. To leave no record, no trace, takes extraordinary effort and resources. Or to be completely off grid, living like a neolithic nomad; the same as not existing at all. -- Even in 2000s, Seisent was being used to solve cold cases. Queries to identify suspects. Big data to reveal any one without an allibi. It's like the 1,000s of rape kits, collected but unprocessed. Why? What possible reason can there be to not investigate? To not close those cases? We can only guess. Perhaps the people responsible don't want to know.
