I wouldn't have tagged it, and I wouldn't have reported it either...if it looked like it was going to stay where it was for awhile, and I was near a road, I might try to call the game warden to let him put it down...otherwise, if it was obvious the thing was suffering, I'd just dispatch him quickly. Some game wardens would hammer you for that, because as far as I know, there isn't anything in the code about putting wounded deer down.
