This page contains links to materials for the ISIS/Extremism Community Briefing, first public presentation on 25 January 2016 in Mount Vernon, Missouri, updated for presentation in Springfield on 20 June 2016 and Mount Vernon on 09 August 2016. The briefing will consist of a talk, question/answer session, and additional reading materials. We have divided the presentation into several sub-presentations so that we can mix-and-match for different audiences and time-slots.
