His ego came through a bit in the book, but honestly that's a fairly common trait for young guys. I am also quite aware that the book only presents one side of the story and that Mitnick had quite a different perspective. I'm sure the truth lies somewhere in the middle. My enjoyment of the book was much more about the process they used to track him down, and the detailed description of them building tools to aid in the process, rather than the people involved.
