The majority of the mishandling took place under Chretien who tried to sweep Khadr under the rug because he personally vouched for the release of Khadr's father who was imprisoned in Pakistan as a known terrorist.

If Chretien didn't press Pakistan for the release of a known terrorist it's highly likely that Omar would have never left Canada and created this mess under his father's influence in the first place.

Khadr's supposed Gitmo sleep deprivation "torture" was all done during Chretien's watch. Harper just delayed his release until the Supreme Court made the ruling forcing him to request for the release.

There were a lot of underhanded, slimy dealings Chretien lied to Canadians about including how involved we were in the Iraq invasion which Wikileaks shed light on so don't be letting Chretien off the hook so easily.
