A Must Read to Know More About Snowden
Edward Lucas presents a well researched book that digs through all the things that have happened since the first story published was with material from the leaked files. He presents to the readers how an intelligence agency actually works, the lack of actual evidence of illegal activities by the NSA and its allies in the stories produced from the Snowden files, and he tries to connect to dots about how Snowden got to be where he is today. Whether you believe Snowden is a saint or a traitor, this short book gives a clearer picture of what has happened and explains who has most to gain from these leaks and it should be read by both sides. Although the people supporting Snowden have a hard time accepting criticism, they should read this book to keep an open mind about this situation. Well researched and well written, this book is a must read. ( )
