What is it that the National Security Agency began doing after 9/11 that necessitated Presidential authorization for warantless surveillance? .....
My guess is the government decided after 9/11 to monitor everyone.Thanks JMC for pointing out that the USA PATRIOT Improvement and Reauthorization Act Of 2005 contains a Section 126, inserted by the House, requiring the Attorney General to submit a report to Congress "on any initiative of the Department of Justice that uses or is intended to develop pattern-based data-mining technology."
Data-mining is defined in Section 126 as:
"a query or search or other analysis of one or more electronic databases, where--
(A) at least one of the databases was obtained from or remains under the control of a non-Federal entity, or the information was acquired initially by another department or agency of the Federal Government for purposes other than intelligence or law enforcement;
(B) the search does not use personal identifiers of a specific individual or does not utilize inputs that appear on their face to identify or be associated with a specified individual to acquire information; and
(C) a department or agency of the Federal Government is conducting the query or search or other analysis to find a pattern indicating terrorist or other criminal activity.
