Reading this nearly four years after the first Snowden revelations renewed my anger at the scope and nature of U.S. government surveillance. The only defense offered for warrantless, indiscriminate mass surveillance is that it prevents terrorism. However, no evidence has been offered to support this claim, nor is there a reasonable discussion of (if it has prevented attacks) whether the loss of privacy is a cost worth paying.
The discussion in chapter four is the best discussion of the right to privacy that I have seen. The best single sentence summary of the book is at the beginning of that chapter: “Governments around the world have made vigorous attempts to train citizens to disdain their own privacy.”
