The Khadr story is  a case study for journalism students. 

They will discover how a complex legal case was misrepresented for a critical period of time;  how the media used highly charged and inaccurate information that served to vilify Khadr, how some media routinely issued the Harper press release with its strategy to demonize Khadr,  how there was initially little effort to inform the public about the true nature of a military tribunal, how Khadt became a scapegoat for anti-Muslim and racist attitudes. The Toronto Sun initially posted the address of Zaynab Khadr in a story when a demonstration was being planned at her home. They did take it down, but this was very ugly.
It's not hard to understand why so many Canadians hate Khadr. Their opinions were formed early in the story when so little was really understood or reported. 

Over time, more accurate, factual reporting took place. Editorials, opeds, documentaries presented the facts to Canadians. But in some cases it was too late
