As a libertarian expose of the overreach of government practices, this book is replete with documented examples from recent (up through 2015) web articles as well as examples from history over the past 60+ years. Chilling to some extent, and well worth the read to examine that perspective.
As a truly 'new' work of examination of the development of a police state in this nation it is not so much a thing... it seemed that every chapter utilized the same source... frequently a web-site... several times over, and individual chapters in the book repeated the same statistics and same sources a few times over. I have a suspicion that the individual chapters might have originally been essays published in other sources (perhaps on the author's own institute's website), but that is only a suspicion and a I haven't researched it to ascertain the veracity of that idea.
I was able to do some internet research concerning the author, his institute, and his associations with other think-tanks and organizations... Yes, I do agree with his thesis that there is much government over-reach in the current socio-political climate, but the hard-right, Christian reconstructionism aspects that I encountered were enough to make me suspicious of the veracity of the civil 'liberties' espoused by the author and his institute.
Nevertheless, there were other aspects, picayune points if you will, that caused me to take pause... there was one work that was spelled one way in one chapter, another way in a different chapter (a compound word vs two separate words), and the lack of notation of (TM) or (R) when referring to two trade-name products.
