I completely dropped the ball on this one. Back in October, University of Michigan Law Professor Yale Kamisar came to UW to talk about Miranda. If you have gone to law school in the past two or three decades, you have probably heard of the professor. His Modern Criminal Procedure book is the standard bearer of legal textbooks.
You can watch the lecture on the rise and decline of Miranda at this link.
I was reminded of the lecture after reading Orin Kerr’s post at the Volokh Conspiracy.
