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.

The MLCA, passed in 1986, further enhanced the BSA by making
