Lone-actor terrorism has unfortunately been on the rise in recent decades, causing major adverse societal effects in the United States and abroad. While lone-actor terrorists can be driven by a range of identifiable factors such as extremist views or availability of weapons, the process of becoming and identifying these individuals is deeply complicated. Lone-Actor Terrorism: An Integrated Framework outlines the societal causes and impacts of lone-actor terrorism from a multi-disciplinary, international perspective. Drawing together seasoned insights across clinical and forensic mental health, sociology, criminology, law, military and intelligence, and security, this volume explores patterns common to lone-actor terrorists across four major sections: historical and case examples, clinical aspects, non-clinical professional and allied perspectives, and assessment and potential approaches to reducing the risk of lone-actor terrorism. Contributors describe both individual clinical factors affecting lone-actors, including developmental aspects, mental health variables, psychoactive drugs, psychometrics and linguists, along with broader social factors such as propaganda and rhetoric, social media, and geographical considerations. This volume concludes with a review of the available threat and risk assessment tools applicable to lone-actor terrorism cases and provides guidance for professionals seeking to reduce risk. While there is no uniform approach to the concept of lone-actor terrorism, this edited volume provides a diverse yet authoritative overview for those interested in better understanding the threats of lone-actor terrorism and its professional response.
