William Rehnquist,
United States v. Verdugo-Urquidez…
“ We think that the text of the Fourth Amendment, its history, and our cases discussing the application of the Constitution to aliens and extraterritorially require rejection of respondent's claim. At the time of the search, he was a citizen and resident of Mexico with no voluntary attachment to the United States, and the place searched was located in Mexico. Under these circumstances, the Fourth Amendment has no application.For better or for worse, we live in a world of nation-states in which our Government must be able to "functio [n] effectively in the company of sovereign nations." ”
