Ah yes because it's only those "anti-American Canadians" that are politicizing the case

Leaving aside all of them (and AI and the UN, but not our government since Harper couldn't care less), and leaving aside my personal disgust with the whole Gitmo/International Law fiasco, what do you actually make of the legal issues that have been raised in the case?
For example being tried a third time after the first trial was thrown out by the Supreme Court? and the second by the military judge?
... or "damning" video footage being declared prejudicial to the case and being barred by the current judge - but mysteriously said secret footage some how got leaked to CBS a week later?
... or having his civilian legal counsel barred from talking or visiting him?
... or the prosecution withholding testimony and evidence from the defense - specifically eyewitness testimony from a soldier that states it wasn't Omar that threw the grenade? (in the case of the murder charge).
... strong allegations by US military personnel that Omar's confession was obtained under extreme (and illegal) duress: ie. the witholding of pain medication to quote "soften him up" post-op?
As you can see there are some interesting non-political legal questions raised by the whole process - for example how does this case fit in with the practice and context of UCMJ and American domestic law? or where does the case fall into the American legal system with regards to the appeals and sentencing process?
*Now as for Canadian domestic and military law it is illegal to try a minor as an adult without a Supreme Court ruling allowing it.... and it is most certainly illegal to hold the accused in custody without legal recourse until such time that they reach the age of majority (pesky Charter of Rights and Freedoms, Human Rights Code, and all that). All of that aside the reason the both the Liberal and Conservative governments haven't got involved is simple, Omar and the Khadr family are a political grenade - there is (or was) equal parts outrage and disgust with him and his family as there where and are calls for Canadian governmental involvement in his case... basically public opinion is pulling in two directions at once even amongst the more hawkish or pro-American segments of society, conflict between seeing him (and his family) punished and the idea of Canadian sovereignty and the Rule of Law ~ and no government wants to (or wants to be seen) handle something that could easily blow up in their face, particularly after the Maher Arar disaster... (of course the whole thing could also blow up on them if they don't get involved "in the right way", ala Maher Arar).
