FBI head: terror fight requires open backdoors to encrypted user data

James Comey says makers should have keys to encrypted devices as he points to growing difficulty of law enforcement at hearing on San Bernardino shooting

FBI director James Comey called on tech companies to create backdoor access to their users' data on Wednesday, arguing it was necessary to tackle everything from terrorism to child kidnapping.

In a hearing about the San Bernardino massacre, Comey said keys to encrypted devices should be held by device manufacturers "so that they could comply with judicial orders".
