This seminar will examine a set of issues of contemporary academic and/or public concern in three principal areas of constitutional criminal procedure: Search and Seizure (Fourth Amendment); Confession Suppression (Miranda and Fifth Amendment); and Impermissibly Suggestive Identifications (Due Process). These general subjects are covered initially in the Criminal Procedure Investigation Course. This seminar will focus on several specific issues and pursue them in greater depth, and it will consider other criminal procedure guarantees, including the prosecutor's obligation to provide exculpatory evidence to the defense. As part of the consideration of several issues, the seminar will examine aspects of the Duke Lacrosse case. Mixed into many of the discussions will be the impact of enhanced concern for erroneous conviction of the innocent on criminal procedure.
