The Supreme Court heard oral arguments on United States v. Jones, which questions the notion that advances in technology alter a person's reasonable expectation of privacy. The case specifically involves the question of the necessity of police needing a warrant before secretly attaching a Global Positioning System (GPS) device to a suspect's car. Antoine Jones, a nightclub owner in Washington, D.C., challenged his conviction for drug trafficking, asserting that the police violated his Fourth Amendment rights when, without a valid warrant or his consent, officers placed a GPS device on his car to track his movements on public streets.
