This young man is obviously well "young". Are you telling me when you were lets say 17 you didn't make mistakes or take marginal shots?
No. When I was 17, I never took marginal shots. When I was 12, I never took marginal shots. When I was 25, I never took marginal shots. When I was 45, I never took marginal shots. I'm 52, and I still don't take marginal shots. Know why? Because I was taught not to. I was taught to respect the animal enough to not take a shot that I wasn't sure of. Know why? I'll tell you why. Because I would have had to face the folks that taught me how to hunt. That's why. They taught me better than that. No excuses.
BlkPwder and Bronko said it all. Flinging arrows and taking potshots at targets that are obstructed by brush is not only unethical, but unneccesary. There's tons of information available just about everywhere you would like to look regarding ethical bowhunting behaviour. Considering that this young man can't be old enough to not have been able to grasp and remember what was preached at the HTE course he had to take is highly unlikely.
It's these kinds of antics that give hunters, bowhunters in particular, a bad name and these types of hunters are a bigger threat to our sport than any kind of division from within. That's the messege. Take it and run with it or turn a blind eye to it. The choice is yours
I still say he outta be grounded for a month.
