I disagree. If ethics trump regulation, there is no moral obligation to turn yourself in. Turning yourself in is just a good idea to avoid harsh penalties and a bad reputation among LEOs.
I break traffic laws every day. It would be absurd to go turn myself in for every infraction.
I think you have somewhat of a point when it comes to practicality, but not principle. I understand the traffic example, however, when you see the blueberries in your mirror to you immediately pull over? Do you accept the ticket? Do you plead guilty? Or, do you try to "get away with it" and avoid the consequences? If you are willing to stand up and take the consequence and not avoid them, you are yielding.
I would also suggest that when I break the traffic laws on a regular basis, it is not because I'm making an ethical choice that is trumping the law. Perhaps if I'm rushing someone to the hospital with a life threatening condition, I would be making an ethical choice, but we don't do this on a daily basis. When I violate the traffic laws, it is out of selfishness, not out of an ethical choice.
Hopefully, folks are not shooting deer illegally on a regular basis based on an ethical choice either. I see no ethical basis for saying I'm going to intentionally violate regulations and shoot deer without proper authorization. That boils down to selfishness pure and simple. On the other hand, someone who make the ethical choice like putting a severely wounded animal out of its misery and turns themselves in, they are saying that they respect that law and are taking responsibility for breaking it. The ethical point is not to avoid harsher penalties (although that is often the result), it to ensure that choice is really ethical and we are not fooling ourselves in to thinking our selfish choices are really ethical ones. In fact, 90+% of the time, if you do not turn yourself in there are zero consequences, and if you do turn yourself in there are usually some consequences, even if they are less severe than if you hide it and get caught. For example, a game warden may decide not to charge you if you make an obvious ethical choice and turn yourself in with no threat of getting caught, but they will often confiscate the game.
When I say that ethics trumps regulations, I mean when there is a conflict between my ethics and the law, ethics will prevail. I'm not saying that each time we break the law it is an ethical choice.
