In ''Illinois v. Caballes'', 533 U.S. 27 (2005), a 7-2 [[U.S. Supreme Court]] upheld the use of drug-sniffing dogs without probable cause and without a warrant to smell for drugs outside the trunk of a car stopped for speeding. The rationale was that the drugs could only detect unlawful activity in the trunk of the car, and thus there was no violation of the [[Fourth Amendment]]. | In ''Illinois v.
