Illinois+v.+Caballes

__Facts of the case__ Roy Caballes was pulled over for a speeding violation on an interstate highway, while waiting in the state trooper's car the trooper radioed his stop and a state police drug interdiction member overheard and arrived at the site. Craig Graham arrived with a drug sniffing dog and went around the perimeter of Caballes' car, the dog signaled the trunk and Graham discovered marijuana. Caballes was charged with drug trafficking and had a 256,136$ fine.

__Majority Rule__ The majority rule was that the stop for a traffic violation was not prolonged by the drug sniffing dog, and the investigation did not invade his expectations of privacy therefore it did not violate the fourth amendment.

__Minority Rule__ The minority rule was that the typical traffic stop was turned into a drug investigation and it was unauthorized search and that it was unjustified, there was no records of evidence of any drugs being present in Caballes' vehicle.
