Canada supposedly has its kangaroo courts through the various federal and provincial human rights commissions; the United States has its kangaroo court at Guantanamo. Prime Minister Harper supports the Gitmo kangaroo court and the US military jurisdiction to torture and try a Canadian citizen.
The problem with Omar Khadr is that he does not have blond hair, blue eyes, and peachy-white skin like many other Canadians. If Khadr's family were devout peachy-white Christians and if Omar had converted to Islam, he would have been back on Canadian soil several years ago.
The problem with Khadr is that he is the wrong kind of Canadian.
