In a 6-2 opinion (minus the Chief Justice), the Supreme Court today held in Illinois v. Caballes that the use of a police dog to sniff the exterior of a car during a lawful traffic stop for drugs does not implicate the privacy rights protected by the 4th Amendment. Writing for the Court, Justice Stevens opines: . . . the use of a well-trained narcotics-detection dog — one that "does not expose noncontraband items that otherwise would remain hidden from public view," Place, 462 U. S., at 707 — during a lawful traffic stop, generally does not implicate legitimate privacy interests. In this case, the dog sniff was performed on the exterior of respondent's car while he was lawfully seized for a traffic violation. Any intrusion on respondent's privacy expectations does not rise to the level of a constitutionally cognizable infringement. This conclusion is entirely consistent with our recent decision that the use of a thermal-imaging device to detect the growth of marijuana in a home constituted an unlawful search. Kyllo v. United States, 533 U. S. 27 (2001). Critical to that decision was the fact that the device was capable of detecting lawful activity — in that case, intimate details in a home, such as "at what hour each night the lady of the house takes her daily sauna and bath." Id., at 38. The legitimate expectation that information about perfectly lawful activity will remain private is categorically distinguishable from respondent's hopes or expectations concerning the nondetection of contraband in the trunk of his car. A dog sniff conducted during a concededly lawful traffic stop that reveals no information other than the location of a substance that no individual has any right to possess does not violate the Fourth Amendment.
