The crime of pretending to be another individual in order to deceive others and gain some advantage.
The crime of false impersonation is defined by federal statutes and by state statutes that differ from jurisdiction to jurisdiction. In some states, pretending to be someone who does not actually exist can constitute false impersonation. For example, suppose Bill attempts to evade prosecution for a crime by giving the arresting officer a fictitious name and address. In Colorado, where "[a] person who knowingly assumes a false or fictitious identity and, under that identity, does any other act intending unlawfully to gain a benefit for himself is guilty of criminal impersonation," Bill could be charged with a crime (Colo. Rev. Stat. Ann. § 18-5-113 [West 1996]). In this situation, the benefit Bill hopes to realize is avoiding prosecution, so that element of the offense has been satisfied. To be charged, the defendant does not need to seek a monetary benefit from the impersonation.
In New York, giving only a fictitious name does not constitute false impersonation. Under New York law, criminal impersonation is committed when an individual "[i]mpersonates another and does an act in such assumed character with intent to obtain a benefit or to injure or defraud another"(N.Y. Penal Law § 190.25 [McK-inney 1996]). In other words, it is illegal to impersonate a real person, but not a fictitious one. Thus, if Carol forges Ann's name on checks made out to Ann so that Carol can cash the checks, Carol could be guilty of false impersonation—but only if Ann is a real person. Such laws are designed to protect innocent people from the losses they may incur owing to the wrongful acts of others and to restore any loss of dignity and reputation they may have suffered as a result of impersonation.
Most state laws also provide that the impersonation of a public official is a criminal act. In Texas, impersonating "a public servant with intent to induce another to submit to his pretended official authority or to rely on his pretended official acts" is a crime (Tex. Penal Code Ann. § 37.11 [West 1996]). Depending on the jurisdiction, the public servant being impersonated does not always have to actually exist. For example, suppose Carl pulls over a driver, shows her a fake police badge, and reprimands her for speeding but tells her that he will not arrest her if she pays him $50. Carl's actions constitute the crime of false impersonation, in addition to any other crimes, including EXTORTION, that may apply to the situation. Thousands of criminal reports are filed every year by individuals victimized in various ways by persons impersonating police officers.
Under federal law, pretending to be "an officer or employee acting under the authority of the United States" in order to demand or obtain "any money, paper, document, or thing of value" can result in a fine as well as imprisonment for up to three years (18 U.S.C.A. § 912). Like state false impersonation statutes, the federal law also seeks to protect interests such as the dignity and prestige of individuals, especially those who hold federal office. Federal statutes also prohibit other types of impersonation, including pretending to be a U.S. citizen; pretending to be a U.S. officer or employee attempting to arrest or search a person or search a building; pretending to be a creditor of the United States or a foreign official; and pretending to be an agent or member of 4-H or of the Red Cross.
