6pt, you hit on the point I was going to make: all the meat is eaten by the locals.
The other point I want to stress is that although the video you saw might be in bad taste, sport hunting of elephants has done more to keep that animal alive. Without the money coming in to hunt them, poachers would be shooting them for their ivory. And their killing is indiscriminate. With hunters, it is managed. In many African countries, there are now more elephants than they care to have. It is only the other countrries that haven't figured out how to manage wildlife where the elephant's population is wavering.
