There are more guns in Zimbabwe than most other parts of Africa. If the locals really wanted that elephant gone, it would have been machine gunned by two guys arriving on foot.
What really happened here is that a hunting party arrived, killed an elephant and left the carcass for the locals to eat.
What a hero.
PS: I spent my childhood and early 20's in South Africa and we hate this great-white-hunter tourist shit, but it sure pays the bills if you're the driver guide or booking agent.
