After the Quebec City mosque shooting, Fox News stated that the killer was Muslim.  Trudeau corrected this, and Rona Ambrose upbraided him for "wasting time" by doing so.  Now, Rempel goes on Tucker Carlson's show -- wow!
The Conservatives are playing pure dog-whistle politics here -- again.  To fall for their rhetoric, you must ignore that Khadr's "confession" was made under duress, and would  likely not stand up in any real court: you must be unaware that the original American battle reports strongly suggest that Khadr did not throw a grenade; you must ignore the facts that he was a manipulated 15 year old child, and that Canada failed in its obligations to him, and that he has spent over ten years in custody without a fair trial.  
I looked at the "Khadr Questions" website; it is amateurish and gravely misleading.  The survey that comes attached to it is an absolute joke.  
The more people know the facts about his case, the less animosity they have toward him and this settlement.
