I think it's deeper than that. There's an incentive on not going against your own military because doing so would attract the wrong kind of mentality and makes things worse when you need them. So unless there are real consequences against brushing it off (like burning down public buildings) that's usually what happens. But publicly people cannot be too explicit saying it because it plays on the image of the pristine rule of law that our politicians like so much to use on speeches to make sure we're above China and other developing countries on the moral grounds.
