I haven't heard the argument so maybe it's getting into that. But my understanding--based on a few articles--is that the case is (at least partly?) about geofencing information stored on Google's servers. E.g. https://www.npr.org/2026/04/27/nx-s1-5777656/supreme-court-g...

"But after two months of working the case, all leads had gone dry. So police applied for a geofence warrant directed at Google and all its collected and stored cellphone location information.

A state magistrate judge found probable cause to issue the warrant and authorized the disclosure of Google's location information for an area the size of about three football fields around the Midlothian bank at the time of the robbery."
