A surveillance program known as Catcher’s Mitt is curtailed, and ten to twenty al-Qaeda wiretaps, as well as some Hamas wiretaps, are not renewed. This follows the discovery of errors in applications for warrants under the Foreign Intelligence Surveillance Act (FISA) related to both al-Qaeda and Hamas and the introduction of new procedures (see Summer 2000-September 11, 2001, Summer-October 2000, October 2000, and March 2001). [New York Times, 9/19/2001; Newsweek, 5/27/2002; Newsweek, 3/29/2004] In addition, other similar programs such as Able Danger and Monarch Passage are shut down at the same time (see (February-March 2001) and January-March 2001).
