A reference for law enforcement and security organizations tasked with protecting the welfare of an individual or groups of individuals, this volume offers suggestions and guidance for confronting high-threat scenarios as well as the more mundane protective details. Detailing the essence of protective operations that are run, in large part, covertly, the book explores operational security, situational awareness, and surveillance detection and includes examples from real-world attacks occurring over the past sixty years. Focusing on the economics of providing the most protection for the least cost, it also addresses issues surrounding possible direct violations of the law and department policy and procedures.
