When he was asked by Oregon Senator Ron Wyden, “Does the NSA collect any type of data at all on millions or hundreds of millions of Americans?”

Director of National Intelligence and Admiral James Clapper: “No, sir.”

Wyden: “It does not?”

Clapper: “Not wittingly. There are cases where they could inadvertently perhaps collect, but not wittingly.”

^These are the people you're saying "aren't asking" for the ability. They are asking for a universal lock picking kit and the legal authority to strong-arm any manufacturer into allowing access to the keys for their devices as well. If you honestly believe that they wouldn't use these tools for other cases beyond this one phone, I've got this amazing bridge you may be interested in.

And I never said anything about a single phone. I fully expect that the FBI would use this capability to unlock lots of other phones either with the owner's permission, or with a warrant. (Just as they do today, with every other type of phone.)

Then you do not understand the security model of the phone, and should take the time the learn the actual issue before making statements in support of the FBI.
