In reply to Dave Garnett:
It sounds as though those who were organising the hunt must carry a large part of the blame here. Big game hunting is legal in many African countries on a strictly controlled basis. It's unlikely that a wealthy overseas punter will know whether or not they are within a Park, or will have any personal knowledge of the animal the are shooting. This is the Ranger's/ professional hunter's responsibility.
I do question the use of a bow though. It's unlikely to have anything like the power to achieve a clean kill that a hunting rifle has.
Personally I would have no desire to hunt a wild animal at home or abroad, be it a lion or a pheasant, but there are those that do. Is it morally right to vilify them any more than someone who goes out rough shooting with a shotgun on a British farm?
In African countries it's a major source of income on game reserves which goes towards managed conservation and the war against illegal poaching which is wiping out some species. Without it many poorer countries like Zimbabwe will see their precious and dwindling animal resources wiped out.
I was in the Kruger national park in January this year where I talked to some of the Rangers and an anti poaching patrol. They were saying that the elephant population has grown too large and a major cull is due.
Yes the Rangers can and do cull, but as this is essential management it makes econometric sense to get revenue from wealthy overseas hunters still hunting under the guidance of professional hunters/guides who will identify the targets to be shot. These will include aging and sick animals.
These professional hunter/guides carry a heavy responsibility, and in the dentist's case that certainly appears to have gone badly wrong.
