Perhaps you should read the SCC decision. Mr Anglin is entitled to his opinion, as are you. Had the Harper government made restitution, and insisted on a fair trial for Mr Khadr, (in Canada, not a kangaroo court in America) the matter might have been settled years ago.
The Harper government did not accept the SC ruling; fr some reason they believed that they knew better. It cost over five million dollars to try to sway the Court- to no avail.
We can now put the matter to rest and let Mr Khadr get on with his life.
