Timmeh, first time hunters would be the ones that should know BEST to not hunt like that... in order to get a hunting license you need to take the hunter's safety course, which presumably, would outline those kind of things. Unless, of course, one took the course, and didn't hunt for another 20 years after, and would hence forget.
I have no problem with the deer being shot, if done so in a legal manner (as some have pointed out). I mean, kids who live on farms befriend lots of animals that end up on the dinner table. People own dogs and cats, and they don't live forever either. You want a deer for a pet -- an animal with a legal hunting season -- then you will always risk experiencing that kind of loss. But hunting is not the "old wild west," and there are rules that must be followed -- for the safety of everyone. And not retrieving the deer... I mean, what the heck is that all about? They obviously knew they were doing something wrong and should be treated accordingly.
