Earlier quoted context omitted.
The key point for me is even if we assume that security blunders like this or say keeping a private email server are ignorance rather than malice ignorance is unacceptable at this level of government. Where's the security officer at advising these officials and helping them do it right? That has to be someone's job right?
That someone also is replaced if he gets on the nerves of the guy he is advising to much, at least on this level. Parallel advising/control structures only work if they have someone higher up they can fall back on if necessary.
Maybe we need a secret service for tech that's outside the command structure of these agencies.
