Better Border Security: Going Beyond Watch Lists

The Syrian refugee and migrant crisis is overwhelming Europe. The reality of ISIS fighters entering in the guise of refugees, has made it clear that watch lists are not enough to secure borders. Furthermore, 6,000 Europeans—including 1,800 French—have left home and joined ISIS in their war.1 Among the French, 118 returned to France in 2014.2 The question is, where are those people now? It is unlikely that all of them will be on a watch list.
