William O. Douglas,
Gilbert v. California (388 U.S. 263…
“ Prior to this case, police could enter and search a house without a warrant only incidental to a valid arrest. If this judgment stands, the police can search a house for evidence, even though the suspect is not arrested. The purpose of the search is, in the words of the California Supreme Court, 'limited to and incident to the purpose of the officers' entry'-that is, to apprehend the suspected criminal. Under that doctrine, the police are given license to search for any evidence linking the homeowner with the crime. ”
