I like the idea of cutting a chunk out of the tongue or something like that, especially if you think there might be people following it and their hit wasn't a killing shot or if you need to leave the deer to retrieve it later. I'm not sure a warden would be able to do much in a situation like that, I just don't know that they'll get involved or be able to say it's his deer not his deer. I had a slightly similar situation last season, hit a buck and wounded it (non-lethal shot) and pushed it to within 30 yards of my buddy and he dropped it. I followed the blood trail right to him and we looked the deer over, saw my hit wasn't good, and he tagged it.
