The organizers of this symposium gave us the choice of writing about effective assistance of counsel or about teaching criminal procedure. I've decided to do both. This article discusses teaching the criminal procedure course most often called "Police Practices," for which I write a textbook entitled Regulation of Police Investigation: Legal, Historical, Empirical and Comparative Materials.' Borrowing heavily from the Teacher's Manual for that book, the first part of this article describes my general philosophy for teaching the course. The rest of the article illustrates this philosophy by describing how I teach students about the application of the Sixth Amendment right to counsel to the interrogation process and to the conduct of identification procedures.
