Since Gen Hagee IS in the direct chain of command of these soldiers, then his failure to entrust this information with reliable people, and the subsequent damage this has caused to their right to a fair trial, means that unlawful command influence has tainted this trial.
Unlawful Command influence INCLUDES the perception that the accused cannot receive a fair trial.
I will never believe that any of these soldiers, from Col Chessani on down, has done a single thing wrong. If convicted of any of these politically motivated charges, then it is at this point MORE RATIONAL to conclude that they are political victims than that they have actually committed any crimes.
