In Fourth Amendment terms, intrusion into a person's reasonable expectation of privacy is described as a what?

• A. REP
• B. Katz
• C. Search
• D. Olmstead

Answer: (C)

Intrusion into a person's reasonable expectation of privacy is described as a search under the Fourth Amendment. The idea comes from Katz v. United States, which established that the Fourth Amendment protects people, not places, and introduced the reasonable expectation of privacy (REP) test. When the government acts in a way that intrudes on that protected privacy—whether through physical intrusion, eavesdropping, or electronic surveillance—it triggers Fourth Amendment protections by constituting a search. If there is no reasonable expectation of privacy or the government action doesn’t infringe on one, it may not be considered a search. The REP concept is the standard used to judge what counts as a search; Katz defines the standard, and the word “search” describes government activity that violates a protected privacy interest. Olmstead is an older case about wiretapping and trespass that helped set the historical backdrop but doesn’t define the modern description.
