The US interagency National Counterterrorism Center (NCTC) maintains a watch list of 325,000 names of international terrorism suspects, a number that has more than quadrupled since the the list was created in 2003 by merging other watch lists together. NCTC officials estimate that, due to aliases, some 200,000 individuals are represented on the list. The main US watch list at the time of 9/11 had 60,000 names on it (see December 11, 1999). An administration official says, “The vast majority are non-US persons and do not live in the US.” However, officials refuse to state how many on the list are US citizens and how many names on the list were obtained through the controversial wiretapping program run by the National Security Agency (NSA). Civil liberties and privacy advocates claim that the scale of the list heightens their concerns that watch lists include the names of large numbers of innocent people. Attorney General Alberto Gonzales tells the Senate Judiciary Committee that he cannot discuss specifics but says, “Information is collected, information is retained, and information disseminated in a way to protect the privacy interests of all Americans.” A September 2003 presidential directive instructs agencies to supply data for the list only about people who are “known or appropriately suspected to be… engaged in conduct constituting, in preparation for, in aid of, or related to terrorism.” Marc Rotenberg, executive director of the Electronic Privacy Information Center, says the scope of the NCTC list highlights the “false positive” problem, in which innocent people have been stopped from flying because their names are wrongly included or are similar to suspects’ names. “If there are that many people on the list, a lot of them probably shouldn’t be there. But how are they ever going to get off?” [Washington Post, 2/15/2006] Numerous problems with the list will be found in 2006 (see March 2006).
