We have been discussing phone records. Not email.
Not sure what you mean by security key for email systems.
Can you provide more info on “One person who was running an email account and refused to hand over the security keys to the NSA had his entire business shut down.”
That’s a rather vague example.
Perhaps you could educate us on the email aspects of this topic.
Google Lavabit. Or Silent Circle.
You are so informed you should already know this. Perhaps you are a government troll???
