To some extent, the US government does merely reflect the paranoia and action-at-any-cost attitude of its citizens, as it, and they, go about their daily business of paying mere lip service to freedom and little else. They're also complicit in seeing to it that the culture they govern continues to promote this social trait.
Even so, a democracy which has voted away all its freedom, still can no longer be described as 'free'.
Also, re-reading your previous post, for part #1, parallel construction means there are numerous, in fact literally uncountable (without top secret clearance, anyway), examples of that. Which, to my mind, is a solid start on #2.
