The stalking typologies that have evolved fall short, however, when we attempt to use them to understand persons who have pursued the President of the United States. Because of this shortcoming, the author (a consultant to the United States Secret Service) has had to develop a unique framework for understanding persons who have threatened, approached, or attacked Presidents of the United States or have appeared at the White House without invitation. The author has developed a technique that integrates psychiatric diagnosis with a conceptualization of what is known about others who have acted similarly. By codifying their actions based on motive, presence or absence of delusions, active psychosis, and intent to do harm, the author presents five descriptive categories that he suggests capture the various motivations of presidential stalkers and assassins and characterize the clinical context in which the behavior occurs.
