What is a Licensed Private Investigator?
A licensed private investigator is sometimes referred to as a P.I., detective, gumshoe, sleuth and sometimes even a spy. In general, the terms refer to a person who uncovers facts and information, finds missing persons and gathers evidence, usually at the request of a private citizen or a company for which they are employed.
Detectives often work for attorneys and lawyers in both civil and criminal court cases. In addition, many professional investigators work for insurance companies to investigate suspicious or fraudulent insurance claims.
Most states require P.I.’s to be licensed and some may be permitted to carry firearms (guns) depending on local and state laws. Some detectives have prior military experience and many worked as a police officer or law enforcement official. Due to the nature of their work, PI’s keep detailed notes and records during each case and often testify in court regarding their observations on behalf of their clients.
Detectives often work irregular hours, especially when conducting surveillance (e.g., sitting outside a subject’s house during early morning hours hoping to get a photograph or video of their activity).

Job Functions
In many cases, spouses hire professional investigators to obtain proof of adultery or other illegal conduct to establish grounds for a divorce. In fact, collecting evidence of adultery or other bad behavior by cheating spouses and partners is one of the most common and profitable services offered.
Also, PI’s provide process serving services, which is the delivery of subpoenas and other legal documents to parties who are involved in a legal case. Many detective agencies specialize in a particular field of expertise. For example, some agencies deal only in skip tracing related to finding missing persons or tracking down debtors.
While others may specialize in technical surveillance countermeasures, which involves locating and dealing with unwanted forms of electronic surveillance (for example, an electronically bugged boardroom for industrial espionage purposes).
Increasingly, detectives prefer to be known as “professional investigators”. This may be a response to the sometimes negative image that is attributed to the P.I. profession and an effort to establish the industry to be a proper and respectable profession.
The U.S. Department of Labor, Bureau of Labor Statistics publishes an article in the Occupational Outlook Handbook for Private Detectives and Investigators, that describes the nature of the work, working conditions, qualifications, employment, training and advancement, earnings, job outlook, and related occupations. If you want to become a private detective, this is a great place to begin.
