In U.S. v. Mendenhall (1980) 446 U.S. 544, two Drug Enforcement Administration (DEA) agents were stationed at the Detroit Metropolitan Airport for the purpose of detecting narcotics smuggling. The agents observed the defendant walking through the airport and concluded that her conduct was consistent with that of persons who unlawfully smuggle narcotics. The agents approached the defendant and asked to see her driver's license and airline ticket. After discovering that the ticket and driver's license contained two entirely different names, the agents asked further questions and identified themselves as DEA agents. (U.S. v. Mendenhall, supra, 446 U.S. 544, 547-548.) The U.S. Supreme Court found that no seizure of the defendant occurred. "The events took place in the public concourse. The agents . . . requested, but did not demand to see the respondent's identification and ticket. Such conduct, without more, did not amount to an intrusion upon any constitutionally protected interest. The respondent was not seized simply by reason of the fact that the agents approached her, asked her if she would show them her ticket and identification, and posed to her a few questions. Nor was it enough to establish a seizure that the person asking the questions was a law enforcement official. . . . In short, nothing in the record suggests that the respondent had any objective reason to believe that she was not free to end the conversation in the concourse and proceed on her way . . . ." (U.S. v. Mendenhall, supra, 446 U.S. 544, 555.)
