In the days following the attacks, concern and rhetoric turned towards the issue of refugees. In October, from refugee camps in France, Full Measure reported on the potential for ISIS terrorists to travel into Europe posing as refugees.

Full Measure spoke to Jim Hanson with the Center for Security Policy, a former member of US Army Special Forces and author of, 'Cut Down the Black Flag, A Plan to Defeat the Islamic State'.
