You inserted the can of worms into the openerwhen you asked what the correct protocol is.
Why is it a can of worms? It's an honest question.
The can of worms comes from this. You brought up the question of what the correct protocol is in this situation. Do you tag it or not was your concern. Then afterwards you became concerned about potential ethical issues should you decide not to tag. At least that's how I read it. Combining those two concerns it looks to me like a can of worms is all I was saying, since this is a public forum.
I really don't care one way or the other what you do. Only you know if that deer is yours or not and only you can decide what the corrrect course of action is. It doesn't affect me either way.
