That they didn't means either the instructor disagrees with your judgment about how dangerous those divers really are (very possible - some things look really dangerous to beginners, where more experienced eyes just see noobs learning the way noobs do) or that they just didn't care (the "quality comes from the instructor" point I was trying to make).
