Judge Refuses to Release Documents in Facebook Decryption Case

A U.S. judge rejected a bid by two civil rights groups that had sought to force the release of documents describing a secret U.S. government effort to compel Facebook to decrypt voice conversations between users on its Messenger app. The issue arose in a joint federal and state investigation into activities of the MS-13 gang in Fresno, revolving around the end-to-end encryption Facebook uses to protect calls on its Messenger service from interception.
