Evocative Evisceration Of Everyday "Evidence". In this text, Katwala shows the origins and history of the polygraph "lie detector" device that has been banned from many courtrooms due to its unreliability yet which lives on in the American zeitgeist. Katwala tells the tale via narrative nonfiction that places the reader in the center of the action and cases in question, then follows the principle players throughout their lifetimes as they try to justify their life's work. In the process, Katwala does a tremendous job of showing how truly unreliable these devices are, and even includes a brief discussion of more modern successor technologies such as brain wave scanners. Anyone interested in the American justice system absolutely needs to read this history of this long-debunked zombie junk science. Indeed, the only negative here is that the bibliography is scant at just 12% or so of the narrative, compared to a more common 20-30% in my experience, and thus the single star deduction. Very much recommended.
