This whole argument is quite silly...
ISIS declared war, the World should declare war back and intern ALL of those suspected of jihhad into POW camps. The guy in South of France yesterday would not have been able to commit 4 murders.
Further who is NOT in uniform like this:
When arrested should be treated as spy and shot...No different then in World War 2...
Simple ;)
They try to kill us and we give them shelter and welfare...
Stupid ;)
