It's great that the authorities snuffed out this terrorist, but why wait until he murders people.? It is always an afterthought. Whoever these perpetrators are, ALL immigrants, asylum seekers, refugees and the such should be subjected to extreme vetting and in many cases banned from entry if they originate from any one of dozens of terrorist countries. 

Call this intervention what you like but I along with many others I am sure, are sick and tired of all this politically correct garbage.  Our safety should come first....!!
