The head of Canada's national police resigned Wednesday amid criticism over his handling of a case in which a Canadian citizen was deported by the United States to Syria where he says he was tortured. On Tuesday, Royal Canadian Mounted Police Commissioner Giuliano Zaccardelli admitted he got his facts wrong when he testified at a House of Commons committee in September about when he first knew the RCMP had passed erroneous information to US authorities about Maher Arar. An inquiry concluded that the information, which suggested Arar had ties to al-Qaida, likely led the US to deport him to Syria where he says he was tortured. "Commissioner Zaccardelli submitted his resignation to me and I have accepted it," Prime Minister Stephen Harper said. "The commissioner has indicated to me that it would be in the best interests of the RCMP to have new leadership."
