Unless I'm off base, I think he's that by leaving them in the ravine or where they were killed will make tasty vittles for the bush pig. In LE circles, it's thought to be the best way to get rid of a body, unless of course you are coastal.The first thing that came to my mind was how this story reinforces the argument that lawful hunting is not the problem. That the dollars that legal, ethical hunting brings in seems to be the most effective manner to combat these animals (the two-legged kind). It seems that those opposed to hunting just refuse to face the reality of what's going on in the world.
But...like Phil, it's early and I haven't had my second cup of coffee yet so maybe I'm missing the point as well.
