The author has had a very, very impressive career helping to champion the art of hostage negotiation within the FBI. It goes into detail on both Ruby Ridge and Waco, which has coincidentally been mentioned in a couple of other books I have recently read (like Educated) so it's been good to get that additional context on American history.
Obviously Gary Noesner's done a lot of great things and has saved a lot of people but I felt at times he was patting himself on the back a bit too much. There was a lot of “I'm right and you're wrong” which I wanted to take seriously but at the same time felt like I had to take with a grain of salt due to the heavy bias throughout the book.
