Nobody complains too loudly if you fire a torpedo at a blue whale, but there would be dire consequences if you hit the wrong sub. I wouldn't call sonar contacts

Nobody complains too loudly if you fire a torpedo at a blue whale, but there would be dire consequences if you hit the wrong sub. I wouldn't call sonar contacts statistical evidence though, even if it is partially correct. The counter example doesn't fit. In you example the sub is hostile because it is Russian. Here the people are convicted to death by circumstantial evidence. Very, very bad circumstantial evidence. It is just "worth" it because there are little consequences for the murderers.
