For law students of constitutional criminal procedure, Principles of Investigative Criminal Procedure will assist them in learning about Fourth, Fifth, and Sixth Amendment issues associated with criminal investigations. This volume is an effort to provide a comprehensive, though "Concise," treatise for law students and attorneys. The materials discuss and analyze the criminal procedure jurisprudence of the United States Supreme Court, with extensive use of primary source material that affects judges, prosecutors, defense counsel, and criminal defendants. Discussions relate to breakthrough decisions like Miranda v. Arizona and United States v. Jones, as well as lower court cases adding a nuance to topics already well-developed in prior Court decisions. "The Court" is a phrase used hundreds of times as a shorthand reference to the work of the United States Supreme Court. Footnotes provide specific page citations in United States Reports for a quick reference to Westlaw. The coverage of this book extends to United States Supreme Court cases through the 2023-2024 Term.
