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
