Mrs. Rodriguez was “hesitant” and balked at least once, but that when the agents told her that they could obtain a search warrant she said that they could “go ahead and look in the room” or “nodded her head” after repeated requests.
Although this record could have supported a conclusion that Mrs. Rodriguez did not give effective consent, Judge Aspen found that “[h]er only hesitancy was over whether she could consent to the search of the union storage area.” Once she resolved that question in her own mind, she approved. This finding is not clearly erroneous.
Mrs. Rodriguez’s possession of the key gave her apparent authority to consent. Apparent authority is enough. Just as police may have probable cause to act even though their source was lying, so they may act when the person giving consent had apparent authority. United States v. Miller, 800 F.2d 129, 133 (7th Cir.1986); United States v. Sledge, 650 F.2d 1075, 1077-81 (9th Cir.1981) (Kennedy, J.); United States v. Isom, 588 F.2d 858, 861 (2d Cir.1978); United States v. Peterson, 524 F.2d 167, 180 (4th Cir.1975); cf. United States v. Matlock, 415 U.S. 164, 177 n. 14, 94 S.Ct. 988, 996 n. 14, 39 L.Ed.2d 242 (1974) (reserving the question). The question posed by the Fourth Amendment is whether the search is “reasonable”, and it is reasonable to act on the basis of apparently valid consent. Going beneath the surface of the information in hand — whether furnished by an eyewitness, see Gramenos v. Jewel Companies, Inc., 797 F.2d 432, 437-41 (7th Cir.1986), or by a person giving consent — would make the outcome of the search depend on niceties of property or marital law far removed from the concerns of the Fourth Amendment. Consents would become untrustworthy unless the police spent additional time investigating the authority of the person who gave consent, which in a ease like ours would require knowledge of Illinois domestic relations law and the living arrangements of the couple. Suppressing evidence because of what the police did not know at the time, even though their acts were justified on the basis of what they did know, would inject a random element into Fourth Amendment jurisprudence without serving any of the functions of the exclusionary rule. Denying police the ability to act on the basis of apparent authority would not deter improper conduct; it would instead deter acting on the basis of consents. Nix v. Alaska, 621 P.2d 1347, 1349-50 (Alaska 1981). Any wrong done to Rodriguez was done by his wife, not by the agents who entered the room on the basis of her apparent authority. Suppression is an inappropriate response. •
To say that Mrs. Rodriguez consented to a search of the janitors’ room is not necessarily to say that she consented to a search of the items it contained. The prosecutor does not contend that Mrs. Rodriguez had even apparent authority to consent to a search of her husband’s briefcase, or that she gave such consent. None of the versions to which the agents testified— whether Mrs. Rodriguez said “If you want to go ahead on in, go on in” or “go ahead and look in the room” or just nodded — included reference to containers such as briefcases. Suppose Rodriguez had checked his briefcase with United Airlines for a flight. United could have consented to a search of its baggage handling facilities, in which passengers anyway lack privacy interests; no one thinks that United could consent to a search of all luggage in its possession. So too with checkrooms at restaurants, parcels in transit with express companies, and other containers in public places. Many a closed container is accessible; opening it requires justification, United States v. Chadwick, 433 U.S. 1, 97 S.Ct. 2476, 53 L.Ed.2d 538 (1977), just as turning over a stereo system to observe its serial number requires justification. Arizona v. Hicks, 480 U.S. 321, 107 S.Ct. 1149, 94 L.Ed.2d 347 (1987). See O’Connor v. Ortega, 480 U.S. 709, 716, 107 S.Ct. 1492, 1498, 94 L.Ed.2d 714 (plurality opinion), p. 731, 107 S.Ct. p. 1509 (Scalia, J., concurring), p. 737, 107 S.Ct. p. 1505 (Blackmun, J., dissenting) (1987); Paulino v. United States, — U.S. -, 109 S.Ct. 1967, 104 L.Ed.2d 435 (1989) (White, J., dissenting from the denial of certiorari). Paulino involved rif
