The Harper government spent a fortune fighting Khadr in the courts and mostly losing.

Now the same Party and its supporters are attacking the government for not fighting yet another battle it would probably lose.  

They ignore the two Supreme Court decisions that Canada was complicit in the violation of Khadr's rights at Gtmo.  

They ignore that if the Harper government had responded properly to the first Court decision in 2008, had it followed a court order to request Khadr's return, had it listened to former PM Martin saying his government had been wrong not to do it and had they accepted the recommendation of all the Opposition  parties to request Khadr's return and give him a fair trial here, the government could have argued they at least tried to remedy the situation.

Instead the Harper government spent years demonizing him, tried to renege on the transfer deal with the US, gave into US pressure then continued demonizing and fighting him in the courts.
