Omar Khadr - A Canadian in Guantánamo Bay

i read the Globe & Mail newspaper and they recently published an article about Omar Khadr.

if you aren't familiar with the story:

• Omar Khadr is a Canadian by birth
  
• his father was close to Osama Bin Laden and his family (at one point) lived in the Bin Laden compound
  
• currently being held in Guantánamo Bay on charges of killing an American soldier
  
• at the time of the incident he was a teenager (14 or 15)
  
• he is being held as an "unlawful combatant" with limited access to lawyers
  

while i had been aware (from media reports) that he was accused of killing an American solder, it wasn't until i read this article that i first learned:

...
During a deadly 2002 battle, U.S. forces raided an alleged al-Qaeda compound killing all inside save one.

The Pentagon alleges it was Omar Khadr who survived the attack to throw a grenade at U.S. soldiers, killing one and blinding another.
...

thoughts on the subject:

• it would appear that being designated an "unlawful combatant" makes retaliating against ones attackers illegal?
  
• while Omar Khadr's case/situation is complicated - why isn't it explored more in the Canadian media? (both from his perspective and that of the US government?)
  
• this editorial in the same day's Globe & Mail paper suggests the Canadian Government should be speaking out more on his behalf - but falls short on exploring why the issues around the case are so controversial
  
• should the Canadian government assume presumption of innocence for citizen's abroad and work to ensure their right to petition for Habeas Corpus?
