Why should Zaccardelli resign? Why should he apologize? Arar fit a profile: too bad!!
Did the RCMP send him back? No. Therefore it was not the RCMP's fault
On September 26, 2002, during a stopover in New York en route from Tunis to Montreal, Arar was detained by the United States Immigration and Naturalization Service who were acting upon false and misleading information information supplied by the RCMP. Despite carrying a Canadian passport, he was deported to Syria in accordance with a U.S. policy known as "extraordinary rendition".

Shoddy Police work pure and simple at it's best. God help those who are innocent and the RCMP get you in their sights, how many innocent people have to go to jail for crimes they didn't commit (like Arar) before this organization is held accountable to the public. The RCMP screwed up and had this young man picked up in the States as a Torrist suspect based on "lies" and faulty Intel he was tortured and god knows what damage to his person will be long term. At least the US used the phrase "Terrorist Suspect" Canadian RCMP called him "A person of Interest". He was owed an apology to say the least.
