The video of Canadian Security Intelligence Service agents questioning 16-year-old Omar Khadr in Guantanamo Bay, Cuba revealed many things. As has been said, it gave Canadians a glimpse of a CSIS interrogation and of the CSIS's methods of gathering intelligence.

But it also revealed something much more troubling: That the Canadian government -- both Liberal and Conservative -- far from merely acquiescing in the United States' decision to hold enemy combatants without charges or legal counsel, has been an active participant in the process.

In the video, which was shot in 2003, not long after the U.S. opened the prison in Cuba, Khadr appears elated upon first meeting the agents, saying he had long requested a hearing with the Canadian government.

But after realizing that the agents were not there to help him, Khadr, who had been sleep-deprived before the interrogation, collapsed into sobs, saying what has variously been interpreted as "kill me," "help me" and "ya ummi" ("Oh mother" in Arabic).
