The ninth edition of this criminal procedure casebook incorporates significant rulings of the Court since the last edition--most notably, Carpenter v. United States (whether acquisition of historical cell site location records is a search), Collins v. Virginia (whether the automobile exception allows warrantless entries onto curtilage), Kansas v. Glover (whether knowledge that a vehicle's registered owner has a revoked license gives rise to a reasonable suspicion justifying a stop), and Byrd v. United States (whether a person not on a rental car contract but permitted to use a car by the renter has "standing" to object to a search). The text has been streamlined with the hope of assisting instructors pressed for time. Chapter Six (Entrapment) has been eliminated and a number of previously main cases have been reduced to note status.

Finally, the problems for most of the chapters have been refreshed with a sampling of cutting-edge rulings by lower courts.
