Apparently this big trophy hunting is almost an exclusively American thing. The need to kill things will big guns must be some small-penis compensation mechanism. That's the only theory I can come up with.
I have no problem at all with people hunting to eat - it is entirely different (as long as they do it cleanly). Especially when a native population kill and animal and use almost every part of it.
But for a photo and a trophy? Lame, lame, lame. Especially when it isn't a clean kill but a 40 hour slow painful death.
IMO the Dentist deserved to be harassed and hounded at the very least - he should be jailed. Small fines are obviously no deterrent for someone with lots of money and no morals. At least enough harassment may put off other idiots from doing the same thing.
