The book demonstrates how to offer testimony on direct examination, how to cross-examine and impeach various types of witnesses, and how to use discovery in the examination of witnesses. The authors illustrate model examinations and offer citations to rules and cases that can be relied upon by an advocate preparing an examination on an important point. The Fifth Edition adds new material addressing the many authentication issues that can arise as digital evidence is presented at trial. The authors have drawn upon excellent work by others to present the new material so that it is clear and understandable.
