Editing Private investigator (section)

==Responsibilities==
Private investigators also engage in a variety of work not often associated with the industry in the mind of the public. For example, many are involved in [[service of process|process serving]], the personal delivery of summons, [[subpoena]]s, 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. <!-- not encyclopedic The best known of these firms in the U.S. include Granite Island Group, Confidential Research & Investigations LLC, Murray & Associates,SLC Security Services LLC and TSCM/Special Operations Group Inc. -->

Other PIs, also known as corporate investigators, specialize in corporate matters, including antifraud work, loss prevention, internal investigations of employee misconduct (such as [[Equal Employment Opportunity Commission|Equal Employment Opportunities]] violations and sexual harassment), the protection of [[intellectual property]] and [[trade secret]]s, 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]].<ref name="main" />
