Why did the supreme court held that the fourth amendment did not apply to wiretaps?

The Supreme Court held that the Fourth Amendment did not apply to wiretaps in the 1928 case Olmstead v. United States, reasoning that the amendment protects against physical intrusions and searches of tangible property, rather than the interception of communications. The Court concluded that since wiretapping did not involve a physical entry into a home or property, it did not constitute an unreasonable search or seizure. This decision was later revisited and refined in subsequent cases, reflecting evolving interpretations of privacy rights.
