The second annual CASIS West Coast Security Conference brought together international tactical, academic, practitioner, intelligence, and defence perspectives on engaging with and addressing violent transnational social movements. Building upon our second edition, Volume 2, Issue 3 takes these different perspectives and presents them in a clear, and coherent manner. The following pieces are a reflection of presentations and discussion panels that took place during our two-day conference. The conference is unique because it generates both academic research and policy-relevant knowledge. This edition may be used to inform responses to emerging national and international security threats of a non-traditional and often ambiguous nature.
