What are some US Supreme Court cases relevant to the Fourth Amendment taking place before the 2000?

Several significant U.S. Supreme Court cases prior to 2000 have shaped Fourth Amendment jurisprudence. In Mapp v. Ohio (1961), the Court established the exclusionary rule, which prevents illegally obtained evidence from being used in court. Katz v. United States (1967) expanded the definition of "search" to include electronic surveillance, emphasizing the protection of privacy. Additionally, Terry v. Ohio (1968) upheld the constitutionality of "stop and frisk" procedures, allowing police to stop individuals based on reasonable suspicion.
