"This Tenth Edition plays to what we feel were the strengths of the first nine editions. While the predominant focus is on Supreme Court jurisprudence, we have tried wherever possible to give the reader a sense of what the lower courts are doing with the interesting and exciting issues that abound in criminal procedure. The lower courts are where the day-to-day law is made, and where many of the most interesting fact situations arise. Since our topic is "American" Criminal Procedure, we have made an effort to include cases from all the circuits and state courts throughout the book". -- PREFACE.
