Suppose there is a controversial issue of constitutional law.  Where does one go for authoritative exposition? We continue what is essentially a discussion of expertise and authority.  How do you know whom to trust?  Who has the right answers?  How might we go about finding out these things?  We continue to look at these questions in several arenas:  scholars, scholarship, and schools.  Interesting sidelights abound, as usual, and a Friendly detour finds an unusual consensus in the “who’s the best” category.
