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: This card installed without a hitch on my Dell Dimension with Windows XP Pro (Service Pack 2). It wasn't even necessary to install any drivers; Windows simply detected the new FireWire and USB devices and installed them without prompting.The device works great. I noticed a huge increase in transfer speeds coming off my USB 2.0 capable digital camera (my Dell came stocked with USB 1.1 only).I would definitely recommend this PCI card!
