Private Investigators – Who They Are and What They Do

Private investigators, also known as PIs, work independently or for a private investigation agency to gather information and conduct investigations. Individuals, organizations hire them, and businesses collect information and evidence for various reasons, including, but not limited to, criminal defense, insurance fraud, background checks, and infidelity investigations.

The role of private investigators is to gather and analyze information, interview witnesses, and use various forms of technology and equipment to uncover the facts and evidence in a case. They work with clients to understand their needs and tailor their services to meet those needs. They may also work with lawyers, insurance companies, and other organizations to assist with legal and insurance claims.

The history of private investigation dates back to the mid-19th century when Pinkerton National Detective Agency was established in 1850. This agency was one of the first private detective agencies in the United States and became well-known for solving high-profile cases and providing private security services. Today, private investigators are licensed professionals who undergo rigorous training and follow strict ethical guidelines.

Private investigators use various techniques and methods to gather information and evidence. For example, they may conduct surveillance, interview witnesses and suspects, collect and analyze public records, and use various forms of technology, such as GPS tracking devices and computer forensics, to uncover information. They may also be called upon to serve subpoenas or to assist with legal proceedings by providing expert testimony.


One of the main challenges of being a private investigator is balancing the client’s needs with the legal and ethical guidelines that govern their work. For example, private investigators must abide by laws related to privacy, search and seizure, and the use of electronic surveillance. They must also be careful to avoid entrapment, tampering with evidence, and other unethical practices.

Private investigators must have excellent communication and interpersonal skills and strong analytical and problem-solving skills. They must also have a good understanding of the law and the criminal justice system, as well as experience with technology and the use of various forms of equipment. Many private investigators have prior experience in law enforcement or military service, and many have a background in criminal justice or a related field.

Becoming a private investigator typically requires completing a training program and obtaining a license from the state where they wish to work. Many states have specific requirements for private investigators, including passing a background check, completing a certain number of hours of training, and passing an exam. Some private investigators may also become certified through a professional organization, such as the National Association of Private Investigators. If Need help securing evidience of cheating?
