At Tactical Response Security Consulting, Inc., we often encounter questions about the various roles within the security and investigation field. A common point of confusion is the distinction between a detective and a private investigator. While both roles involve uncovering information, their jurisdictions, methods, and the types of cases they handle are fundamentally different. Understanding this difference is key for anyone looking to hire a private investigator for their specific needs. 
Jurisdiction and Authority
Public detectives are law enforcement officers employed by a government entity, granting them the authority to make arrests and enforce laws within a specific public jurisdiction. In contrast, the licensed private investigators are private citizens hired by individuals or corporations. The authority is limited to the private investigation services they are contracted for.The Nature of the Cases
Detectives primarily handle criminal cases like theft, assault, or homicide. The work of private detectives and investigators, however, often revolves around civil matters or corporate concerns. This can include background checks, infidelity cases, locating missing persons, or gathering evidence for a civil lawsuit. We provide the specific, personal investigator services that law enforcement cannot.Methods and Resources
While detectives have access to vast government databases and resources, a licensed private investigator relies on public records, surveillance, and interviews. Our expertise lies in knowing how to legally and ethically gather information that is not readily available, providing our clients with the detailed reports they need to make informed decisions and achieve their objectives.
