SCOTUS says detailed cellphone location data is protected by the Fourth Amendment
The Supreme Court ruled that detailed cellphone location data is protected by the Fourth Amendment, requiring law enforcement to obtain warrants with probable cause before accessing such information from tech companies, fundamentally changing how police can use geofence warrants.
