A private investigator, private detective, PI, or private eye, is a person who undertakes investigations, usually for a private citizen or some other entity not involved with a government or police organization. They often work for attorneys in civil cases or on behalf of a defense attorney. Many work for insurance companies to investigate suspicious claims. Before the advent of no-fault divorce, many private investigators were hired to search out evidence of adultery or other illegal conduct within marriage to establish grounds for a divorce. Despite the lack of legal necessity for such evidence in many jurisdictions, according to press reports collecting evidence of adultery or other “bad behavior” by spouses and partners is still one of the most profitable activities investigators undertake.
Many jurisdictions require PIs to be licensed, and they may or may not carry firearms depending on local laws. Some are ex-police offices, although many are not. They are expected to keep detailed notes and to be prepared to testify in court regarding any of their observations on behalf of their clients. Taking great care to remain within the law in the scope is also required, as this may lead to the individual facing criminal charges. Irregular hours may also be required when performing surveillance work.
