Google " Trudeau in Mosque" and check out the pictures. He is in the process of saying the "shahada," There is one god, Allah is God. Mohammad is the prophet of God".  the sacred oath to Islam. All it takes is for a man to say it before another Muslim and ...voila... the deed is done. It is irrevocable, and death is the punishment for apostasy or  breaking the shahada . Did Justin know what he was doing?  We don't know. However, the other people in the mosque know perfectly well what is going on.  The one thing we do know for sure Trudeau felt like  Lawrence of Arabia in his sexy white linen robes. The shahada is the white text on the black flag of ISIS.
