What is an example of a supreme court case that dealt with the 4th amendment?

Katz v. United States is an important Supreme Court case that directly addresses the Fourth Amendment, which protects individuals from unreasonable searches and seizures. This case, decided in 1967, expanded the interpretation of what constitutes a search under the Fourth Amendment.

In Katz, the Supreme Court ruled that the Fourth Amendment protects people, not just physical places. The case involved Charles Katz, who was convicted based on evidence obtained from an FBI wiretap placed on a public phone booth he used to make calls. Katz argued that the wiretap was unconstitutional because it was a search that required a warrant.

The Court held that the FBI's actions violated Katz's reasonable expectation of privacy, establishing the principle that conversations and personal communications are protected from government interception without a warrant. This decision significantly shaped the legal landscape regarding privacy rights and the application of the Fourth Amendment in the context of modern technology, emphasizing that individuals have a right to privacy in public communications.
