Personally I find this kind of shooting utterly ridiculous. Ridiculous are also these people who like retards pose proudly next to their kills as if they achieved something important or difficult. Anyone with money can join a "safari" hunting group, with guides, riding big trucks, everybody armed with machine guns, and with all the luxuries of the modern world. This is not hunting, it's a massacre. What's next, hunting by drone?
Having said this, some natural preserves make money by licensing hunts for exotic animals, and the better ones pick only old animals for shooting. They say that controlled killing helps population control and raises needed funds to keep the preserves operating. I don't know how much of this is true; it may very well be. Yet, nothing takes away from the Trumps being assholes.
