Feds Walk Into A Building, Demand Everyone's Fingerprints To Open Phones

An anonymous reader writes: Forbes reports that the Department of Justice was issued a search warrant to gather the fingerprints of all the people present at a California residence, including residents and visitors.
The memorandum included "authorization to depress the fingerprints and thumbprints of every person who is located at the SUBJECT PREMISES during the execution of the search and who is reasonably believed by law enforcement to be the user of a fingerprint sensor-enabled device that is located at the SUBJECT PREMISES and falls within the scope of the warrant."
