The Supreme Court agreed Friday to decide the constitutionality of broad search warrants that collect the location history of cellphone users to find people near crime scenes.
The case involves what is a known as a “geofence warrant” that was served on Google in a police hunt for a bank robber in suburban Richmond, Virginia. Geofence warrants, an increasingly popular investigative tool, seek location data on every person within a specific location over a certain period of time.
