This third policy paper of the Countering Lone-Actor Terrorism series examines variations in the political engagement and online activity of lone-actor terrorists, and provides recommendations for policy-makers, police and social media companies

Countering Lone-Actor Terrorism Series: No. 7

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 is the third of four policy papers in the CLAT series and is published by the Institute for Strategic Dialogue. Preventing every single instance of lone-actor terrorism is impossible. This is particularly true in countries where freedom of thought, speech and privacy are highly valued and must be protected. The recommendations stemming from this paper's analysis provide practical suggestions for preventing instances of lone-actor terrorism – based on findings relating to motivations, political engagement and online activity – that adhere to these principles.
