I suspect that the US actually wants Mzourdi and Motassadeq out on the street and working on some al-Qaida project...while being watched. These guys simply aren't smart...and would likely lead dozens of folks into traps.
But you know our judges - they´re even more dumb and keep the letter of the law higher than the intentions of the lawmakers. One´s for sure: if these two were that important, the US and Germany would have found ways to solve the problem by now. I agree with you that these two are not that important for Americas authorities.
