An absolutely great thing to happen, in my opinion. A SEAL with immunity from prosecution says he did it which sets up the other SEAL to be freed. Couldn't have happened to a better prosecutor either.
What I thought of when I heard about this was how (and it was portrayed in the movie) Desmond Doss, the 7th Day Adventist medical assistant, who refused to carry a gun in World War II and was the first conscientious objector to receive the Congressional Medal of Honor, saved countless numbers of American soldiers and wounded as well as a few Japaneese wounded soldiers in that conflict. As portrayed in the movie the soldiers who were at the bottom of the cliff who testified about Desmond Doss saving at least three Japaneese wounded soldiers who were said to have died of their wounds (all of them) when they reached the bottom of the hill.
We instill in our soldiers to kill the enemy and today though we are going to consider a life's sentence for doing exactly what they were taught and ordered to do. I'm not trying to justify the killing of anyone but when you politicize war you do a great injustice to our men and women who volunteer to put their lives on the line and put at risk our own Nation. I've never seen war, up close and personal, nor do I care to unless I had to or to defend our Nation and freedoms. The last thing our military and soldiers need is some pencil pusher, who never has, themselves, seen or experienced combat judge and stand in judgement of someone who has and is at risk of dying due to ongoing combat.
