This is a pretty good book, although not nearly as informative as Glenn Greenwald's book, this type of book begs the question: Why only one Edward Snowden at Booz Allen Hamilton [owned by the Carlyle Group]? Why not hundreds? Are the rest traitorous Americans? But then, there was only one Julie Sirrs at the D.I.A., who warned of an impending 9/11 attack in 2000, and brought back the evidence of Unocal and CIA financing and arming of the Taliban and al Qaeda, and was forced out of the DIA - - and only one John Kiriakou at the CIA, and only one Jeffrey Sterling at the CIA, and only one Thomas Drake at the NSA, and only one Cate Jenkins at the EPA [although there was another lady whistleblower there, Dr. Jenkins has been a continuous thorn in their dishonorable side for 20 years or so]? Why only one or two at agencies with thousands upon thousands of employees? And only one Keysha Cooper at WaMu; one honest trader at Merrill Lynch, likewise fired for refusing to undertake illegal activities?
