Cops told: No, you can't have a warrant to force a big bunch of people to unlock their phones by fingerprint, face scans

A US judge last week denied police a warrant to unlock a number of devices using biometrics identifiers like fingerprints and faces, extending more privacy to device owners than previous recent cases.
The order comes from Northern California Federal District Judge Kandis Westmore in response to a request by the government to search and seize the devices found at a premises in Oakland, California, connected to two suspects.
