Despite some success stories, terrorist attacks in recent years have revealed a general lack of information sharing-and failures in communication-between federal, state, and local law enforcement and the intelligence community and private security profession. With the creation of the Department of Homeland Security after 9/11, efforts to share information between these groups has increased, emphasizing the important role private security plays in homeland counterterrorism efforts. Private investigators can provide criminal, civil, and background investigations, protective services, security consulting, and electronic sweeps, making them vital resources in any investigation. Private Investigation and Homeland Security provides a thorough overview of the role of private investigation in homeland security industries and operations, and how such services can be best utilized by both government entities and private sector businesses. Written by a licensed private investigator-drawing upon his years of expertise in private security and experience with the CIA, the book includes the following key features: Dedicated chapters on licensing requirements, business development, and legal issues, Historical background of private investigations, Analysis of the complexities of investigating social media, Commonsense guidelines for conducting various types of investigations, References to key, reliable resources for further reading/follow-up, Private Investigation and Homeland Security serves as an invaluable reference for those new to the field and those hoping to learn more about applying private investigation techniques to a homeland security platform alike.
