the ideology known as the open fields doctrine was first enunciated in the case of
Open-fields doctrine The open fields doctrine was first articulated by the U.S. Supreme Court in Hester v. United States,[3] which stated that “the special protection accorded by the Fourth Amendment to the people in their ‘persons, houses, papers, and effects,’ is not extended to the open fields."[4] This opinion appears to be decided on the basis that "open fields are not a "constitutionally protected area" because they cannot be construed as "persons, houses, papers, [or] effects."
Containment The basis of the doctrine was articulated in a 1946 cable by U.S. diplomat George F. Kennan during the post-World War II administration of U.S. President Harry S. Truman. As a description of U.S. foreign policy, the word originated in a report Kennan submitted to U.S. Defense Secretary James Forrestal in 1947, which was later used in a magazine article. It is a translation of the French term cordon sanitaire, which was used to describe Western policy toward the Soviet Union in the 1920s.
