He was put in Gitmo under Chretien's watch and eventually released under the Harper Government. If anything it's the Liberals who own this fiasco all because of Chretien.

Face reality. We probably wouldn't be dealing with this mess if Chretien didn't use his influence to have the father released from the Pakistani prison in he first place. 

But the idiotic Liberal mindset of a Canadian citizen with known links to Osama in Laden taking precedent over common sense to leave him rotting in a jail where he belonged was too great for Chretien.

Khadr's links to Bin Laden was the political albatross for Chretien and Martin which is why they complied to housing Omar in Gitmo hoping to sweep the Liberal mistake tied to his father's release under the rug. 

I know you're probably going to try and pin this all on Harper but he's only responsible for prolonging the incarceration while he waited for the SCC to make the unpopular ruling ordering the request for his release.
