I have to give Marcia Clark credit; it's takes courage to be as brutally honest about one's own mistakes as she is in this book. She presents here the argument she was only partially able to present in court for a number of reasons. I think this was an honest account of what went on. She explains the scientific terminology used in such a way that I think anyone should able to understand it. Having read this book, I conclude that our American system of justice is one of the best in the world, but it is still flawed--without a doubt.
