I would just like to comment on this disheartening video as I am directly involved in the hunting industry as a professional guide and builder of big bore custom hunting rifles (most of which are used to take big game in Africa, Asia and North America).
"Canned hunts" also known as "put and take" are an ethical thorn in the side of the hunting community as a whole. It happens everywhere, even here in the U.S. I think there is no bigger threat to those of us who hunt fair chase than the public perception of a rich elite gunning down a "wild" animal inside small high fenced enclosures. Unfortunately there are hunting organizations which turn a blind eye to this perversion for one reason: money.
Legal, controlled, fair chase hunting of predators (as opposed to put and take or poaching) will only help in sustaining the populations of the species. Like it or not, animals have economic value, especially in developing countries. Ethical hunters, in cooperation with other wildlife enthusiasts, raise the value of the animal to the point that it is in the people's and the government's best interest to protect them in order to keep the money flowing.
