The latest Greenwald book, and John Whitehead's "A Government of Wolves" are both books that I can only read a little at a time. More than likely the book you've referred to would have the same effect on me. Namely a rage-fueled need to rend and tear . . . .
It does seem as if the pace of instituting repressive policies and practices has increased lately. Although that impression might simply be due to my own increased awareness and edification.
