The Supreme Court has made a ruling on cellphone location data. In a recent decision, the court determined that broad sweeps of this data require warrants. This ruling is related to a case involving a bank robber who was identified using a geofence warrant.

The decision was written by Justice Elena Kagan and was supported by a majority of the court, with a 6-3 vote. The ruling suggests that people have a certain expectation of privacy when it comes to their cellphone location information.

Further details on this ruling are available from NBC 5 Dallas-Fort Worth, including the full decision and its implications.
