Book excerpt: This book serves three types of readers. The first type of reader is one who is going to read this book as study material for the California Private Patrol Operator Qualified Manager Exam A.K.A. PPO Exam or PPO Test. As such, the content was based on the Examination Outline for Private Patrol Operators, and from at least seven years' worth of suggestions from Shaun's colleagues. The second type of reader this book serves are those considering opening a private security company or those who are managing a company and who want a refresher on the current industry standards. This book will explore the basic fundamentals of owning and operating a private security company in California. The third type of reader is that of the attorney who is investigating or prosecuting a negligence case involving a private security company. The intent of this book is to serve as one of the primary legal treatises on private security standards. The reader must understand that although the book contains practice questions, these questions are not the same questions as on the state exam. Neither the same or exact content in the state exam. Remember- no particular author or entity- has legal access to the BSIS exam questions. We do, on the other hand, base our questions from the state Examination Outline.
