I find this program disturbing in that people on 3 boats watched this attack without attempting to assist the mother gray whale and her calf, stop the killer whales, or in some way interfere so the mother and calf could get away. How on earth did those human beings stay so detached and interested? No wonder the world is a mess. I watched very little, had to turn it off. This was another example of human detachment narrated by a zoologist in the guise of education is disgusting. You should be ashamed of yourselves.
