Assassination research occupies a relatively small area of the literature, and progress has been hindered by anomalies in research findings thrown up by variations in the person being targeted, the geographic region, and whether or not the planned attack is actually completed. As such, it is related to, and draws on, studies in homicide, stalking, and terrorism research. Assassination research initially grew out of attempts to “profile” the personality and background characteristics of those who had attacked prominent persons, but over time, research has evolved to take a more risk‐focused approach.
