I ran into ethical vs legal issues a few times, which is bound to happen if you are out in nature. One time I was deer hunting, and like 5 deer were walking out past me, I shot the biggest buck out of the bunch, it dropped right away. It was about 100 yards away. I continue to sit for another hour, and then walked out there. I had 2 deer down off one shot, one was the buck I shot at, the other a doe, the bullet passed through the buck and into the doe. The doe was still alive, so I finished her off. My party (We could party hunt) didnt have an open doe tag. So I called the warded up, he came there, looked at the deer in the field, inspected the wounds, made me buy an extra license, I think it was $21 at the time, then took the doe with him, and said I just donated my doe to someone in need. I was fine with that!
Another indecent, several years later, I was in my stand, and saw a doe with its lower jaw shot off of it, and again none of us had a doe tag. Back then, doe tags were very few and far between. I didnt shoot it when I had the chance, but it laid down in a creek bed, and I figured she was down for the day. When I got back to camp, and told the others about it, we went out and did a drive and kicked her up, and finished her off. Again we called the warden, he came out, looked at the doe, and just said good job, and wrote us a tag for the deer, no charge, and he let us keep it.
The last time wasnt really anything to do with ethics, but it had to do with calling the warden again. I shot my deer on Sunday night of the last day of the season. I tracked it into some large thick stuff, and on property I did not have permission to be on, and at this point it was after 10 pm, so we called off the search until the next day after work. I got ahold of the land owner, and he said he will come along, which was great, more eyes! Anyhow we tracked it and eventually found it, and we had a long drag back, after cleaning it and getting it loaded up, it was again late at night, and the place we register deer at was already closed. I figured I would just take it there after work the next day (Wednesday now), and I would register it, but he said they can only register it 24 hours after the season was closed. So I called the warden up, he wasnt able to come out that day, so he had me bring it into the local county sheriffs office, and have them look at it. He looked at iut, and said, yup, its been dead for a couple days and he wrote me a tag for the deer. All 3 different cases turned out satisfactory in my eyes, and no issues with the law from them. I guess my points were, if you have the choice to be ethical, do it. Deal with the consiquences later if there is any. But usually they are human as well, and will see why you did what you did.
