Book excerpt: Leading off with the O. J. Simpson trial, the author assembles reflections on each phase of his legal career, including being a law school dean and professor, Supreme Court advocate for medical marijuana, critical observer of the criminal justice system, opponent of the death penalty, and executive director of the California study of wrongful convictions, as well as on more personal thoughts about ethical issues. Distinguishing reflections from ruminations, he ends each section with his current take on various proposed reforms of the justice system.
