I think we have to remember that maintaining military discipline is supremely important. The article says only one of them was charged with assault. All three are charged with dereliction of duty and making a false official statement. I’m not sure what the dereliction of duty is about, but in the military, even more than civilian life, making a false official statement is a serious matter and cannot be excused or overlooked.
We do remember that maintaining military discipline is important. HOWEVER, matters can be handled with discretion OR with much publicity and fanfare. The latter was chosen for this case. Remembering that this is a time of war is also part of the military code.
