Kidnapping funds organized crime and terrorism, and damages developing economies by discouraging tourism and foreign investment, straining international alliances and creating human capital flight. Governments have two unattractive choices: allow payment of ransom, and thus encourage more kidnapping, or attempt to stop families and associates from paying, which, if successful, likely sacrifice the life of the hostage. This paper argues for a more vigorous and sophisticated approach: disrupting the business model of kidnapping organizations. The FBI has developed a doctrine of crisis negotiation that has proven effective at undermining the business of kidnapping while still prioritizing the life of the hostage. It steers negotiations in ways likely to produce evidence for eventual prosecution while making negotiations costly and burdensome to kidnappers without provoking an open confrontation. Our goal is to spread the use of these techniques to allied governments and law enforcement organizations.
