The book is called The United States of Paranoia, and VICE‘s Harry Cheadle sat down with Walker to talk about it:
The question of whether you believe in conspiracy theories is surprisingly tricky. You may not think that the moon landing or Beyoncé’s pregnancy was fake, you may not imagine lizards lurking behind Donald Rumsfield and Dick Cheney’s faces, but by now you probably know that the US government is operating a massive secret surveillance apparatus, which would sound like a paranoid fantasy if it weren’t true. And many, many Americans profess some level of credulity when it comes to some conspiracies, which at times can seem less crazy than believing that there’s never, ever, a man behind the curtain pulling strings.

VICE: You take a long historical view of conspiracy theories in America. Do you think we’re more paranoid than we used to be?
Jesse Walker: I don’t think so. I’m not quite sure how I would even measure that, given what the baseline of paranoia is. What I do think happens is that the direction of the paranoia shifts. One thing I mentioned in the book was how a lot of people started saying after Obama got elected, “Ooh, the right wing has suddenly gotten very paranoid.” In fact, in the Bush era, there were tons of right-wing conspiracy theories, it’s just that they weren’t about the government. They were aimed mostly at people outside America’s borders. With another party in power, [the right] has rediscovered some of its libertarian impulses. A lot of discussions about the United States becoming more paranoid or less paranoid just has to do with what kind of paranoia people are paying attention to.The recent revelations about the NSA and FBI’s monitoring of cell phone metadata and internet communications make me wonder if it’s possible that the government itself is paranoid.
I can’t get into the head of the average NSA bureaucrat enacting a program. But I think that the creation of that sort of system obviously has to do with fear and paranoia. I should stress I’m using the word paranoid in a colloquial way. I should just be saying “fear.” Another problem has to do with the way “conspiracy theory” gets used, because people who use the phrase conspiracy theory disparagingly believe in all sorts of conspiracies, it’s just that they say, “Well those are true, so they don’t count.” What they really mean when they say “conspiracy theory” is, at best, “nutty conspiracy theory,” and, at worst, “conspiracy theory that feeds into an ideology that I don’t share, which I will therefore think of as nutty.” But I’ve forgotten your original question.
