Many of the names and some of the identities in this book have been changed. I also disguised some locations and altered the titles of certain organizations. But all the people, places, and institutions are real; they are not composites, and they are not fictional.
Whenever possible, I based the material on written field notes. Some of the stories, however, have been reconstructed from memory. While memory isn’t a perfect substitute for notes, I have tried my best to reproduce conversations and events as faithfully as possible.
