Without the generous cooperation of many people in various settings, including police departments and universities, the variety of examples and particularly illustrations presented in this guide would not have been possible. Some individuals who should have been acknowledged below may have been inadvertently omitted, and I apologize if that is the case.

I am particularly grateful to Nancy
La Vigne, director of the National Institute of Justice (NIJ) Crime Mapping Research Center, who facilitated this project. Several reviewers, anonymous and otherwise, provided invaluable insight that has been incorporated. I am also grateful to my colleague Tom Rabenhorst, former cartographic editor of Annals of the Association of American Geographers, who edited the maps.
Ultimately, all these efforts to spread the blame are in vain, and the author accepts full responsibility for errors, omissions, and misinterpretations.
