A new volume, The Political Heart of Criminal Procedure: Essays on Themes of William J. Stuntz, edited by Michael Klarman, David Skeel, and Carol Steiker. It has essays by several of the leading criminal procedure scholars writing today, and I have a chapter in there, too. Unfortunately, the volume was priced for library purchase, not for individual purchase. But if you go hunting you can find most of the pieces on SSRN for free. You might start with the introduction here.
