On a mild November night last year, nine EU citizens roamed the streets of Paris with guns and explosives, murdering and injuring hundreds of civilians. In the days and weeks afterward, France declared emergency laws, Britain voted to expand the bombing of ISIS in Syria and ISIS supporters launched their own social media response on Twitter with #PrayforRaqqah.
But many of the most important questions around Paris remain unanswered. Where did these men come from? Were they part of a group? Who instructed them to commit these acts?
