Book excerpt: At the intersection of politics, law and national security--from "protect us at all costs" to "what the hell have you guys been up to, anyway?"--A lawyer's life in the CIA. Under seven presidents and 11 different CIA directors, Rizzo rose to become the CIA's most powerful career attorney. Given the agency's dangerous and secret mission, spotting and deterring possible abuses of law, offering guidance and protecting personnel from legal jeopardy was, and remains, no easy task. The author accumulated more than 30 years of war stories, and he tells most of them.
