They dragged a carcass behind a vehicle to lure the lion out of the park where it was protected, shot it with a crossbow and failed to kill it (the dentist is supposed to be an amazing shot), and it took the lion 40 hours to die.
People who sport hunt, especially with bows, talk about the skill of the hunt, having to sometimes stalk their prey for days to get close enough to make a clean kill. These guys baited this lion and served him up in front of this clown and he failed to do the one thing he was meant to do properly, perform a clean kill on a legal animal. Then they tried to hide the radio collar he was wearing, chopped off his head and skinned him. For what? To put him on the wall?
I'm a meat eater, and I have absolutely no problem with sustenance hunting. If you want to kill and process a deer every season to fill your freezer (of which there are millions because they breed like rabbits) then more power to you, you're more in touch about where your food comes from than those that buy it on Styrofoam at the grocers.
But this trophy hunting bullshit, hunting threatened animals for shits and giggles, is simply killing for killing sake, because of a deep seated love for killing. Torturing and killing animals is a trait shared by most serial killers. This guy, and people like him (and there are many), are seriously wired wrong. I wouldn't want him anywhere near my family and friends.
