The article says "Paris prosecutor Francois Molins said late on Saturday that the man, named as 39-year-old Ziyed Ben Belgacem, had shouted he was there to “die for Allah” when he tried to seize a gun from a woman air force member on patrol at Orly airpor".

It also says "Belgacem was born in Paris, according to the prosecutor. French media said his family was of Tunisian origin". 

It seems to show that Muslims who have been moderate for years can suddenly decide to follow the verses in the Qur'an and suddenly lash out in the name of their God and religion to attack, maim and kill non believers or try to attack, maim and kill non believers.

If Muslim terrrorists can get into countries or if Muslims already in countres or born and raised in countries can follow Islam and the verses in the Qur'an and lash out anytime, why then would countries in Europe and in North America want more Muslims?
