[1] Title III of the Act set rules for obtaining wiretap orders in the United States.

[3] Within that amount, $50 million was earmarked for assistance to local law enforcement agencies, which included funds to deal with riot control and organized crime.

[5] The wiretapping section of the bill was passed in part as a response to the U.S. Supreme Court decisions Berger v. New York, 388 U.S. 41 (1967) and Katz v. United States, 389 U.S. 347 (1967), which both limited the power of the government to obtain information from citizens without their consent, based on the protections under the Fourth Amendment to the U.S. Constitution.

In 1975, the United States Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities, (known as the "Church Committee") was established to investigate abuses by the Central Intelligence Agency (CIA), National Security Agency (NSA), Federal Bureau of Investigation (FBI), and the Internal Revenue Service (IRS).

In 1975 and 1976, the Church Committee published 14 reports on various U.S. intelligence agencies' operations, and a report on the FBI's COINTELPRO program stated that "the Fourth Amendment did apply to searches and seizures of conversations and protected all conversations of an individual as to which he had a reasonable expectation of privacy...At no time, however, were the Justice Department's standards and procedures ever applied to NSA's electronic monitoring system and its 'watch listing' of American citizens.

[6] Academic Colin Agur argues that the act "disappoints" from the perspective of Brandeisian legal philosophy, in regards to individual privacy, because it assumes that law enforcement agencies have a right to electronic surveillance, instead of "giving unambiguous priority to individual privacy.

§ 3501 with a clear intent to reverse the effect of the court ruling, included a provision in the Crime Control Act directing federal trial judges to admit statements of criminal defendants if they were made voluntarily, without regard to whether he had received the Miranda warnings.
