Q: This book is not for everyone. It is extremely scary and disturbing. At the same time, it is a fascinating look at the police work and prosecution that brought the murderous Manson Family to justice. The book is hard to put down; the in depth discussion on presenting a criminal case in court and developing evidence to support the case is outstanding. The main complaint is that the book is a few hundred pages too long. The author seems a little too self-promoting, but then again he did get a prosecution on one of the biggest murders in history.

A: Positive

Q: I think beyond the fact that Hazlitt produces a succinct and well-argued explanation for why free markets are the best arrangements in economic relationships, what is really wonderful is reading the screeds of those readers that he pisses off! Read the rabid ranting temper tantrum of the one reader who amazingly was accepted to the University of Chicago and you can see how ideas that actually support free thought and productive profitable endeavors drive lunatics like this crazy - its awesome!! This dork probably marches against the WTO.

A: Positive
