No Greater Threat: America After September 11 and the Rise of a National Security State by C. William Michaels, Wei-Bin Zhang
If you want to read a great synopsis of the USA PATRIOT Act with a full understanding of the legal and law enforcement ramifications of it and see clear lines drawn as to where our nation is headed, this is the book to read. Be prepared to start re-thinking your stance on where the government is headed and how it will affect personal liberties.
Of course, today it is somewhat outdated with the sunsets, renewals, additions, and more that have happened. Other laws, as bad as the USAPA, have come into play now as well. This is a goo starting point if you want to see how the Police State has progressed starting at 9/11/01 to present.
