Which 1967 USSC case established that the Fourth Amendment protects people rather than just property?

The case that established that the Fourth Amendment protects people rather than just property is Katz v. United States. This landmark decision clarified that the Fourth Amendment is concerned with people's reasonable expectations of privacy. In this case, the Supreme Court ruled that the government could not conduct warrantless wiretapping of a public phone booth without violating the Fourth Amendment rights of the individual using it, highlighting that privacy extends beyond physical premises.

The significance of this case lies in its expansion of Fourth Amendment protections to include the privacy of individuals, regardless of their physical property. It shifted the focus from a strictly property-based perspective to a broader understanding of personal privacy rights, which has had a lasting influence on subsequent cases dealing with privacy issues in various contexts.
