Thurgood Marshall, New York v. Harris — Dissenting Opinion
“ Police officers are well aware that simply because a statement is "voluntary" does not mean that it was entirely unaffected by the Fourth Amendment violation. See Brown, supra, 422 U.S., at 601-602, 95 S.Ct., at 2260-2261. Indeed, if the Fourth Amendment required exclusion only of statements taken in violation of the Fifth Amendment, the Fourth Amendment would serve no independent purpose. A regime that suppresses only some fruits of constitutional violations is a regime that barely begins to eliminate the incentives to violate the Constitution. ”
