A systematic analysis of lone-actor terrorists reveals considerable variation in terms of individual characteristics, methodologies, motivations and indicators of violent intent
Countering Lone-Actor Terrorism Series: No. 4
The aim of the Countering Lone-Actor Terrorism (CLAT) project is to understand lone-actor terrorism in a European context. The project will develop a database of lone-actor cases from across Europe. Its overall objective is to see if it is possible to discern any trends or patterns that could be translated into useful observations or recommendations for practitioners and policy-makers.
This fourth paper of the series conducts a detailed examination of the lone-actor terrorist database. The findings reaffirm a key assertion from the earlier literature review: there is no consistent profile for a lone-actor terrorist. However, systematic analysis of cases from across Europe has provided valuable insights into the scale of the threat, the ways in which it is most likely to manifest, and the activities of lone-actor terrorists in the time leading up to the attack.
