It's hard but try to follow this convoluted reasoning. The US prosecutor is happy that he was able to agree to a plea deal with a Taliban terrorist who killed a US Medic and partially blinded a Soldier with a grenade. The prosecutor claims that he wasn't aware that there was a cap on time that convicted Gitmo prisoners could serve. Omar Khadr was sentenced to a long stretch after he pleaded guilty to the killing of the Army Medic and the blinding of a US Soldier and then transferred to a Canadian prison where he could be released in a year. What's the freaking sense in bringing these people to trial if the prosecutor is so dumb that he doesn't realize that it doesn't matter because they can't do a lot of time because the US government apparently agreed to a cap on sentencing.
