Talk:Patriot Act/Draft/Background

Background
The Patriot Act made a number of changes to U.S. law. Key acts changed were the Foreign Intelligence Surveillance Act of 1978 (FISA), the Electronic Communications Privacy Act of 1968 (ECPA), the Money Laundering Control Act of 1986 and Bank Secrecy Act (BSA), as well as the Immigration and Nationality Act.

Title II of the Patriot Act made a number of significant changes to the laws relating to foreign intelligence surveillance, of which the main two Acts that were affected were FISA and the ECPA. FISA came about after the Watergate scandal and subsequent investigations by the Church Committee, which discovered and criticised abuses of domestic spying by the National Security Agency (NSA), Federal Bureau of Investigation (FBI) and Central Intelligence Agency (CIA). This led to widespread congressional and public outcry, resulting in Congress passing FISA in 1978. FISA governs the way in which U.S. intelligence agencies may conduct wiretaps and the interception of communications in order to gather foreign intelligence. FISA established the Foreign Intelligence Surveillance Court (FISC) and a FISC Court of Review which administer foreign intelligence related applications for access to business records, wiretaps, microphone "bugging", physical searches and the use of pen registers and trap and trace devices. The Act does not apply to U.S. citizens, but is limited to dealings with foreign powers and nationals.

The ECPA was an amendment to title III of the Omnibus Crime Control and Safe Streets Act of 1968, which is sometimes known as the "Wiretap statute". The Wiretap statute was mainly the result of two Supreme Court cases &mdash; Katz v. United States and Berger v. New York &mdash; and from criticism by the Church Committee of the actions of COINTELPRO (Counter Intelligence Program). The Supreme Court found in both Katz v. U.S. and Berger v. New York that Fourth Amendment search and seizure protections prohibited warrantless wiretaps. COINTELPRO was a program of the FBI that was aimed at investigating and disrupting dissident political organizations within the United States. COINTERPRO's operations during 1956–1971 were broadly targeted against organizations that were (at the time) considered to have politically radical elements. These included those whose stated goal was the violent overthrow of the U.S. government (such as the Weathermen), non-violent civil rights groups such as Martin Luther King Jr.'s Southern Christian Leadership Conference and violent groups like the Ku Klux Klan and the American Nazi Party. The Church Committee found that most of the surveillance was illegal. Consequently Title III of the Omnibus Crime Control and Safe Streets Act, though noting that wiretaps and interception of communications are a vital part of the law enforcement, found that wiretapping had been undertaken without legal sanction and were being used to overhear the private conversations of U.S. citizens without their consent. These conversations were then often being used as evidence in court proceedings. Therefore, in order to protect the integrity of the courts while also ensuring the privacy of citizens was not violated the Act provided a legal framework within which wiretaps and interceptions of communications could be used. The Act requires a court order authorizing the use of such measures against U.S. citizens, with penalties for those who do not get such authorization. The notable exception to these orders is in section, which makes an exception to the restrictions of wiretaps in cases where the President must take measures to protect the U.S. from actual or potential hostile actions from a foreign power.

When Title III was established telecommunications was in its infancy and since that time many advances in communications technology have been made. This made it necessary to update the law to take into account these new developments. Thus the ECPA was passed, and extended title III to also protect wire, oral and electronic communications while in transit, as well as protecting stored electronic communications. The ECPA also extended the prohibition of the use of pen register and/or trap and trace devices to record dialling information used in the process of transmitting wire or electronic communications without a search warrant.

Along with changes to surveillance measures, the Patriot Act also made substantial changes to laws relating to money laundering. The main law changed was the Money Laundering Control Act (MLCA), which was itself an amendment to the Bank Secrecy Act (BSA) The BSA was passed by Congress in 1970 and is designed to fight drug trafficking, money laundering and other financial crimes. It requires financial institutions to keep records of cash purchases of negotiable instruments, file reports of cash transactions exceeding a daily aggregate amount of $US10,000, and to report suspicious activity that might signify money laundering, tax evasion, or other criminal activities. The MLCA, passed in 1986, further enhanced the BSA by making it a crime to structure transactions in such a way as to avoid BSA reporting requirements.

Immigration law was also tightened under the Patriot Act. The Immigration and Nationality Act of 1952 (INA), also known as the McCarran-Walter Act, was passed by Congress in 1952 and was designed to restrict immigration into the U.S. It allowed the government to deport immigrants or naturalized citizens engaged in subversive activities and also allowed the barring of suspected subversives from entering the country. The Act is codified under Title 8 of the United States Code, which primarily governs immigration and citizenship in the United States. Prior to the INA, a variety of statutes governed immigration law but were not organized within one body of text. The Act was later modified by the Immigration and Nationality Act of 1965, and then by the Immigration Reform and Control Act of 1986. Since the Patriot Act, Title 8 has been modified even further by various Acts, including the Real ID Act of 2005.
