The most significant change in the Seventh Edition deals with the revolution in Confrontation Clause jurisprudence occasioned by the Supreme Court's decisions in Crawford v. Washington (2004) and Davis v. Washington (2006). The confrontation section of the book in Chapter 13 is completely revised and substantially expanded. Extensive notes describe the operation of the earlier system of confrontation analysis, the immediate impact, and the areas of continuing uncertainty under Crawford and Davis. The new edition also continues the trend in the Sixth Edition, which dramatically revamped the book's treatment of scientific evidence, and includes a number of new cases and notes regarding scientific evidence because of the dynamic nature of that particular area of evidence law.
