Messrs. Chretien and Martin were the leaders in power when the two events occurred that have been cited by the SCC as offending the charter rights that Liberals under Pierre Trudeau established for Mr. Khadr's benefit.  Trudeau the younger is the naif who thought he could use our money to buy his way out of the corner Liberals painted the country into, without paying a political price.
Every error in judgement associated with this fiasco lies 100% at the feet of the Liberal Party of Canada despite the efforts of Canada's MSM to paint a different story.
