Justices Dissenting



Washington, D.C.

Date of Decision

10 June 1996


Denied the petitioners' claim and affirmed the decisions of the trial court and court of appeals, ruling that probable cause to believe that a traffic violation has occurred is sufficient justification for the police to stop a vehicle and conduct a search for objects in plain view within that vehicle.

The War on Drugs

Beginning in the early 1980s, the Court interpreted Fourth Amendment prohibitions against unreasonable search and seizure so as to increase the ability of law enforcement authorities to obtain evidence against criminal suspects. This tendency has been particularly apparent in cases involving the trade in illegal drugs, and has generally mirrored public sentiment.
