This investigation was the responsibility of the battalion, regimental, and divsion commander. If they failed to properly investigate, then they should be so charged, not some staff officer. The ultimate outcome of all of this will be the assignment of lawyers at all levels of command serving as political officers, undermining the commander and challenging his judgment, authority, and credibility. This will mean the end of the military.
Too bad the enemy doesn’t get their own set of lawyers, too. Then each side could just sue each other over grievances and skip the combat part of war. /sarc
