You seem confused. 
First Khadr "admitted to throwing the grenade"  in gitmo under torturous  conditions. Tortured convictions are not admissible under Canadian law because they are unreliable. People say anything to make the abuse stop. So there is that.
 Second, this is completely unrelated to Trump and the three separate US government investigations into possible collusion or other wrongdoing.  So let's talk about something more relevant to the point you poorly tried to make. Hypocrisy. 
What of the hypocrisy of "lock her up? " Trump supporters made that a rallying cry again and against Clinton with no evidence. None. Nada. Zip.  Zilch. People said hey that's not fair. Did they listen ? Nope. 
 Now there is a lot more evidence- still circumstantial -that Trump or someone in his campaign colluded to undermine the Democrats. Yet Trump supporters cry foul for a lack of fairness and objectivity when they have offered none. Lol. Seriously?Reap what you sow. You can't have it both ways.
