That's the beginning of a perfectly good argument that the activities of the NSA make the U.S. a surveillance state. (Though I don't, ultimately, agree with it.) But it has nothing to do at all with the topic under discussion which is whether the capability that the FBI seeks to unlock iPhones would turn the U.S. into a surveillance state.

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.)
