This news from Guantanamo Bay — Omar Khadr, the 19-year old Canadian teenager who has been detained for four years — announced he is boycotting his military trial at its opening session Wednesday. Human rights lawyers say Khadr is the first person in modern world history to face a military commission for alleged crimes committed as a child. He is accused of killing a US soldier with a grenade in Afghanistan. Khadr told the judge: “I say with my respect to you and everybody else here that I am boycotting these procedures until I [am] treated humanely and fair.”
