In which of the following cases did the Court hold that any form of electronic surveillance, including wiretapping, that violates a reasonable expectation of privacy, constitutes a search under the Fourth Amendment. No physical trespass is required.a. Berger v. New Yorkb. Kyllo v. United Statesc. Rasual v. Bushd. Katz v. United States

The conflict of the Katz v. United States originated when Katz was caught up transmitting illegal transmission of wagering information over a public phone to clients in other states, however, he had been caught by Federal agents that had attached an eavesdropping device to the outside of the public phone booth that Katz was using.

On Court, Katz argued that the recordings obtained by the agents could not be used as evidence against him because it violated the Fourth Amendment right that protected him against unreasonable search and seizure and required the police to obtain a search warrant before they could search a specified place for evidence.

The Supreme Court ruled in Katz's favor, stating that any form of electronic surveillance without a warrant, including wiretapping, that violates a reasonable expectation of privacy, constitutes a search under the Fourth Amendment.
