I was teaching ethics at UConn Law last Spring. One of the secrets of teaching is that your students will always find visitors much more credible than you. So we all bring in guest lecturers. It also saves on preparing teaching notes. But I had a class where the visitors truly did better than I could have ever done.

The first half of the class was devoted to pro bono. For those who have been away from the books for a while, there are actually ethics rules on the duty of lawyers to do public service work. The commentary to the rules codifies what is the universal situation—the rules are not enforced. They serve hortatory and aspirational purposes but no one enforces them.
