Any JAG oficers here? I didn’t think there was jury screening, except actual conflict of interest, in picking a military Court. There is no jury per se, in a military trial, there is “The Court”, a panel of officers (and enlisted if the defendant is enlisted and requests enlisted members, which most wisely do not) They are appointed by the convening authority, and are on special orders. The judge is there to advise the Court on the law. The head of the Court, that is the senior officer on the panel, is in charge of the proceedings.
Forget what you’ve seen on “A Few Good Men”, or any Hollywood representation of a civilian court. Military trials/courts are different than real civilian courts/trials, and even more different from the Movie/TV versions of those.
I don’t understand why they didn’t forcibly shave Hassan, and cut his hair to be within military regulations. He is still a Major in the US Army and thus still subject to military discipline. In fact he’s supposed to appear in court wearing the appropriate uniform.
