A private investigator (often abbreviated to PI and informally called a private eye), a private detective, or inquiry agent, is a person who can be hired by individuals or groups to undertake investigatory law services. Private detectives/investigators often work for attorneys in civil and criminal cases.
In 1833, Eugène François Vidocq, a French soldier, criminal, and privateer, founded the first known private detective agency, "Le Bureau des Renseignements Universels pour le commerce et l'Industrie" ("The Office of Universal Information For Commerce and Industry") and hired ex-convicts. Official law enforcement tried many times to shut it down. In 1842, police arrested him in suspicion of unlawful imprisonment and taking money on false pretences after he had solved an embezzlement case. Vidocq later suspected that it had been a set-up. He was sentenced for five years with a 3,000-franc fine, but the Court of Appeals released him. Vidocq is credited with having introduced record-keeping, criminology, and ballistics to criminal investigation. He made the first plaster casts of shoe impressions. He created indelible ink and unalterable bond paper with his printing company. His form of anthropometrics is still partially used by French police. He is also credited for philanthropic pursuits – he claimed he never informed on anyone who had stolen for real need.
After Vidocq, the industry was born. Much of what private investigators did in the early days was to act as the police in matters for which their clients felt the police were not equipped or willing to do. A larger role for this new private investigative industry was to assist companies in labor disputes. Some early private investigators provided armed guards to act as a private militia.
In the United Kingdom, Charles Frederick Field set up an enquiry office upon his retirement from the Metropolitan Police in 1852. Field became a friend of Charles Dickens, and the latter wrote articles about him. In 1862, one of his employees, the Hungarian Ignatius Paul Pollaky, left him and set up a rival agency. Although little-remembered today, Pollaky's fame at the time was such that he was mentioned in various books of the 1870s and immortalized as "Paddington" Pollaky for his "keen penetration" in the 1881 comic opera, Patience.
In the United States, Allan Pinkerton established the Pinkerton National Detective Agency - a private detective agency - in 1850. Pinkerton became famous when he foiled a plot to assassinate then President-elect Abraham Lincoln in 1861. Pinkerton's agents performed services which ranged from undercover investigations and detection of crimes, to plant protection and armed security. It is sometimes claimed,[by whom?] probably with exaggeration, that at the height of its existence, the Pinkerton National Detective Agency employed more agents than the United States Army. Allan Pinkerton hired Kate Warne in 1856 as a private detective, making her the first female private detective in America.
During the union unrest in the US in the late 19th century, companies sometimes hired operatives and armed guards from the Pinkertons. In the aftermath of the Homestead Riot of 1892, several states passed so-called "anti-Pinkerton" laws restricting the importation of private security guards during union strikes. The federal Anti-Pinkerton Act of 1893 continues to prohibit an "individual employed by the Pinkerton Detective Agency, or similar organization" from being employed by "the Government of the United States or the government of the District of Columbia."
Pinkerton agents were also hired to track western outlaws Jesse James, the Reno brothers, and the Wild Bunch, including Butch Cassidy and the Sundance Kid. The Pinkerton agency's logo, an eye embellished with the words "We Never Sleep", inspired the term "private eye".
Many private detectives/investigators with specialized academic and practical experience also work with defense attorneys on capital punishment and other criminal defense cases. Many others are insurance investigators who investigate suspicious claims. Before the advent of no-fault divorce, many private investigators were hired to search out evidence of adultery or other 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 behaviour" by spouses and partners is still one of the most profitable activities investigators undertake, as the stakes being fought over now are child custody, alimony, or marital property disputes.
Private investigators can also be used to perform due diligence for an investor who may be considering investing money with an investment group, fund manager, or other high-risk business or investment venture. This could serve to help the prospective investor avoid being the victim of a fraud or Ponzi scheme. By hiring a licensed and experienced investigator, they could unearth information that the investment is risky and or that the investor has suspicious red flags in his or her background. This is called investigative due diligence, and is becoming much more prevalent in the 21st century with the public reports of large-scale Ponzi schemes and fraudulent investment vehicles such as Madoff, Stanford, Petters, Rothstein, and the hundreds of others reported by the SEC and other law-enforcement agencies.
Private investigators also engage in a large variety of work not usually associated with the industry in the mind of the public. For example, many are involved in process serving, the personal delivery of summons, subpoenas, and other legal documents to parties in a legal case. The tracing of absconding debtors can also form a large part of a PI's work load. Many agencies specialize in a particular field of expertise. For example, some PI agencies deal only in tracing. A handful of firms specialize in technical surveillance counter-measures, sometimes called electronic counter measures, which is the locating and dealing with unwanted forms of electronic surveillance (for example, a bugged boardroom for industrial espionage purposes). This niche service is typically conducted by those with backgrounds in intelligence/counterintelligence, executive protection, and a small number from law enforcement entities whose duties included the covert installation of eavesdropping devices as a tool in organized crime, terrorism and narco-trafficking investigations. Other PIs, also known as corporate investigators, specialize in corporate matters, including antifraud work, loss prevention, internal investigations of employee misconduct (such as EEO violations and sexual harassment), the protection of intellectual property and trade secrets, antipiracy, copyright infringement investigations, due diligence investigations, malware and cyber criminal activity, and computer forensics work. Some PIs act as professional witnesses where they observe situations with a view to reporting the actions or lack of them to a court or to gather evidence in antisocial behavior.
An undercover investigator, undercover detective, or undercover agent is a person who conducts investigations of suspected or confirmed criminal activity while impersonating a disinterested third party. Undercover investigators often infiltrate a suspected insurgent group, posing as a person interested in purchasing illegal goods or services with the ultimate aim of obtaining information about their assigned target.
Many undercover investigators carry hidden cameras and recorders strapped to their bodies to help them document their investigations. The period of the investigation could last for several months, or in some extreme cases, years. Due to the dangerous nature of the job, their real identities are kept secret throughout their active careers. Economic investigations, business intelligence and information on competitors, security advice, special security services information, criminal investigation, investigations background, and profile polygraph tests are all typical examples of such a role.
Across the world
Many jurisdictions require PIs to be licensed. Depending on local laws, they may or may not carry a firearm, some are former law enforcement agents (including former police officers), some are former spies, some are former military, some used to work for a private military company, and some are former bodyguards and security guards. While PIs may investigate criminal matters, most do not have police authority, and as such, they are only limited to the powers of citizen's arrest and detainment that any other citizen has. 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. Great care is required to remain within the scope of the law, otherwise the investigator may face criminal charges. Irregular hours may also be required when performing surveillance work.
Private investigators in Australia must be licensed by the licensing authority relevant to the state where they are located. This applies to all states except the Australian Capital Territory. Companies offering investigation services must also hold a business licence and all their operatives must hold individual licences. Generally, the licences are administered and regulated by the state police; however, in some states, this can also be managed by other government agencies.
To become registered in New South Wales requires a CAPI licence, which can be applied for through the NSW Police Force website. The Australian Capital Territory does not require PIs to be licensed, although they are still bound by legislation. PIs working in the ACT cannot enter the NSW area without a CAPI license, else they will be in breach of the law.
In 2001, the government passed the licensing of private investigators and private investigation firms in the UK over to the Security Industry Authority (SIA), which acted as the regulatory body from then on. However, due to the cutbacks of this agency, licensing of private investigators in the UK was halted indefinitely. At present, no government-backed authorities in the UK license private investigators.
The SIA have announced that PIs in the UK were to become licensed for the first time from May 2015, but this is only the scheduled date for the issue to be discussed in parliament. In December 2014, Corporate Livewire produced an article written by a UK private investigator at BAR Investigations, addressing the issues surrounding private investigation in the UK.
Private investigators in the United States are licensed or registered by the professional licensing authority or state police of the state where they are located. Licensing varies from state to state, and can range from just applying for a city business license in three states (Idaho, Mississippi and South Dakota, which have no state or local licensing requirements) to needing several years of experience and licensing-related training classes and testing in other states (such as Virginia, which has some of the highest standards in the country). In general, companies offering investigation services must hold an agency license, and all of their investigators or detectives must hold individual licenses or registrations. A few reciprocity agreements allow a detective working in one state to continue his work in another for a limited time without getting a separate license, but not all states participate in these agreements.
