Reference excerpt

Warrantless searches are searches and seizures conducted without court-issued search warrants. In the United States, warrantless searches are restricted under the Fourth Amendment to the United States Constitution, part of the Bill of Rights, which states, "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."

History In the Thirteen Colonies, agents of the British Empire utilized general warrants to authorize searches in the homes of colonists. Such warrants allowed the holder to search any place for any thing at any time. They were viewed as abuses of power, contributing to increased tensions that ultimately led to the American Revolution. The Fourth Amendment barred all warrantless searches and all general warrants; nevertheless, the interpretation and limitations of the Fourth Amendment and the permissibility of warrantless searches under certain circumstances, such as wartime, have been important in the history of executive and judicial power in the United States. During the American Revolutionary War, "the Continental Congress regularly received quantities of intercepted British and Tory mail". See intelligence in the American Revolutionary War. In 1975, the Church Committee, a United States Senate select committee chaired by Frank Church of Idaho, a Democrat, investigated domestic and foreign Cold War area intelligence-gathering by the federal government, including warrantless surveillance on anti-war advocates inside America. The committee report found the "Americans who violated no criminal law and represented no genuine threat to the 'national security' have been targeted, regardless of the stated predicate. In many cases, the implementation of wiretaps and bugs has also been fraught with procedural violations, even when the required procedures were meager, thus compounding the abuse. The inherently intrusive nature of electronic surveillance, moreover, has enabled the Government to generate vast amounts of information – unrelated to any legitimate governmental interest – about the personal and political lives of American citizens." The "potential criminal liability of the National Security Agency and the Central Intelligence Agency for operations such as SHAMROCK (interception of all international cable traffic from 1945 to 1975) and MINARET (use of watchlists of U.S. dissidents and potential civil disturbers to provide intercept information to law enforcement agencies from 1969 to 1973)" helped persuade president Gerald Ford in 1976 to seek surveillance legislation, which was ultimately enacted as Foreign Intelligence Surveillance Act in 1978. Abuses of power by the federal government led to reform legislation in the 1970s. Advancing technology began to present questions not directly addressed by the legislation as early as 1985. In its 1985 report "Electronic Surveillance and Civil Liberties", the nonpartisan Congressional Office of Technology Assessment suggested legislation be considered for a surveillance oversight board. Congress disbanded this agency in 1995.

Clinton administration On July 14, 1994, President Clinton's Deputy Attorney General and later 9/11 Commission member Jamie Gorelick testified to the Senate Intelligence Committee that "The Department of Justice believes, and the case law supports, that the president has inherent authority to conduct warrantless physical searches for foreign intelligence purposes … and that the president may, as has been done, delegate this authority to the Attorney General." This "inherent authority" was used to search the home of CIA spy Aldrich Ames without a warrant. "It is important to understand", Gorelick continued, "that the rules and methodology for criminal searches are inconsistent with the collection of foreign intelligence and would unduly frustrate the president in carrying out his foreign intelligence responsibilities".

George W. Bush administration

NSA warrantless surveillance controversy

On December 16, 2005, the New York Times printed a story asserting that following 9/11, "President Bush secretly authorized the National Security Agency to eavesdrop on Americans and others inside the United States to search for evidence of terrorist activity without the court-approved warrants ordinarily required for domestic spying", as part of the war on terrorism:

Under a presidential order signed in 2002, the intelligence agency monitored the international telephone calls and international e-mail messages of hundreds, perhaps thousands, of people inside the United States without warrants over the past three years in an effort to track possible "dirty numbers" linked to Al Qaeda, the officials said. The agency, they said, still seeks warrants to monitor entirely domestic communications. The revelation of this program caused a widespread controversy, with legal experts and politicians concluding that it violates the Foreign Intelligence Surveillance Act and other legal experts saying that the FISA law only applied to domestic calls and not to overseas calls and communications that involved a foreign intelligence threat. Bush administration officials such as the Attorney General defended the program by citing that this was a part of the justification that the Clinton administration used in its warrantless search of Aldrich Ames. They claimed that since Ames was spying for a foreign power, presidential power applied and FISA did not.

NSA call database

In May 2006, it was revealed that the Bush administration had also been compiling a database of telephone calls, created by the National Security Agency (NSA) with the cooperation of three of the largest telephone carriers in the United States: AT&T, Verizon, and BellSouth. All three companies were paid to provide the information to the NSA. It is speculated that the database contains over 1.9 trillion call-detail records of phone calls made after September 11, 2001. The database's existence prompted fierce objection from those who viewed it as a warrantless or illegal search – nevertheless, the collection of such third-party information has been authorized by the USA PATRIOT Act, and has been upheld by the courts.

Worked examples

Example 1 — a first encounter with Warrantless searches in the United States

Start with the simplest possible case. Write down what Warrantless searches in the United States claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Warrantless searches in the United States before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Warrantless searches in the United States ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.
