As you might expect, lawyers have a fairly crisply defined set of rules about what their ethical (sorry, "professional") responsibilities are [1]. On the Multi-state Professional Responsibility Exam (part of the bar exam required to practice law), there are questions where you are penalized for selecting an answer that is too ethical (i.e., where you may believe it to be the right thing to do, but where the Code of Professional Responsibility imposes no such duty on you).
