Jeg vil anbefale boken til alle som er interessert i forholdet mellom personvern og ytringsfrihet på den ene siden og statens behov for beskyttelse på den andre siden.

Boken beskriver i detalj Gellmans håndtering av dokumentasjon fra Snowden. Interessant er også kapittelet som gir et bilde av hackermiljøet som driver overvåkning, og kulturen i NSA. Gellman har i tillegg til Snowden også intervjuet diverse myndighetspersoner i NSA og CIA. Det gjentakende spørsmålet er hvilke effekt varslingen har hatt - oppveier de positive konsekvensene av varslingen skadevirkningene for amerikansk etterretning.

Introduksjon på Goodreads.com:

"Dark Mirror is the ultimate inside account of the vast global surveillance network that now pervades all our lives.

Barton Gellman’s informant called himself ‘Verax’ - the truth-teller. It was only later that Verax unmasked himself as Edward Snowden. But Gellman’s primary role in bringing Snowden’s revelations to light, for which he shared the Pulitzer Prize, is only the beginning of this gripping real-life spy story. Snowden unlocked the door: here Gellman describes what he found on the other side over the course of a years-long journey of investigation. It is also the story of his own escalating battle against unknown digital adversaries after he discovered his own name on a file in the leaked document trove and realised that he himself was under attack.

Through a gripping narrative of paranoia, clandestine operations and jaw-dropping revelations, Dark Mirror delineates in full for the first time the hidden superstructure that connects government espionage with Silicon Valley. Who is spying on us and why? Here are the answers."
