The Legal Division Handbook relies essentially on the Supreme Court cases that have developed Fourth, Fifth and Sixth Amendment law. Crucial principles of the law are embedded in the Handbook text with frequent cites to the pertinent cases. This Reference Book provides an opportunity to gain further insight, clarity and understanding of the law by setting out the facts, issues, holding, and rationales of those significant decisions. The cases are listed by subject in the Table of Contents and by name in the Index in the back of this book. This Reference Book is also helpful in preparing for legal examinations. The facts of each case can mimic the material that make up multiple choice test questions. The issue in each case brief can serve as a test question. Students may attempt to answer the question posed in the issue before reading the Supreme Court's answer and rationale as a means of testing knowledge gained from course work and the Handbook. Specific guidance and policies from the Department of Justice and Department of Homeland Security is arranged for quick reference on issues such as: Use of Race, Legal Ethics, Consensual Monitoring, Use of Deadly Force, the Public Safety Exception, Discovery in Criminal Cases, Use, Preservation and Disclosure of eCommunications in Federal Criminal Cases, Electronic Recording of Statements, and Interviewing Government Employees.
