> Can a state policing agency of some kind go and pull purchase records for a credit card by name? Could they extract search history, drive destinations, music lists, or something else without warrant? It's not clear to me where the distinction between "warrant-less search/seizure/wiretap" crosses into "Get all data about a person who is outside their home for free".
Yes, law enforcement routinely goes to private companies to get data without a warrant, oftentimes in cases where a warrant would otherwise be required.
For example, Google only _just_ changed their internal policy of handing location data to LEO without a warrant - and while this sounds like great news, it's not as big as it seems, because other players (e.g. cell carriers) also have that data and are much more likely to hand it over than Google is. https://time.com/6539416/google-location-history-data-police...
