Yes, there has to a scapegoat. Even a few of them, if necessary.
Any scapegoat really. So some unnamed ‘service members’ will do I suppose.
Just so long as blame (and punishment) doesn’t get anywhere near to those who are actually ultimately responsible for those service members being put into the position where they were called on to make this unforgivable tragedy happen. Can’t let that happen. It just wouldn’t do to allow that to happen, would it?
