"In 1995, Ahmed was arrested by Pakistani authorities for his involvement in an al-Qaeda attack on the Egyptian embassy in Pakistan, which killed 15 people. After heavy pressure from the family, Prime Minister Jean Chrétien made an extraordinary personal plea for his release on a state visit to Pakistan. Mr. Khadr was freed"


That's the guy who should apologize to Canada and Canadians. He and his advisors, at the time, should be charged with breach of trust and dereliction of duty for abandoning his responsibility, as leader of Canada, to protect Canadians.  This guy and his Government is still paid handsomely, receives VIP benefits and huge pensions from the taxpayers of Canada. There are very few responsibilities that a leader of a nation has to his citizens and one is security and protection.
He and his Government were paid huge sums of money to anticipate and prepare for future threats to his citizens and nation. He knew or should have known that this group were a threat.
