The moral "High Horse" that I am going to ride into this thread has nothing to do with whether or not it's legal, if they are considered"vermin", or even eating the little thing.
What strikes me is such disregard for life in general........since when is killing FUNNY? I understand the predator instinct, what drives a boy to shoot at live creatures blah blah blah. I at least see a sense of accomplishment and a feeling of pride and "Trophy", But killing an animal, stomping its head and spinning it's crumpled body on an arrow is FUNNY?

Yeah keep encouraging him......

Joe I realize you are a 12 yr old kid, but please think about your actions a bit as you transition into an adult hunter. A respect for all of nature will go a long way to helping you enjoy hunting as recreation.
