New figures show nearly half of the names on the U.S. government’s terrorist watchlist have no known connections to terrorist groups. Citing leaked figures, the website The Intercept reports that of the 680,000 people included, more than 40 percent are recognized as having “no recognized terrorist group affiliation.” The Intercept revealed last month the Obama administration has expanded the watchlist system by approving broad guidelines over who can be targeted, asserting that “irrefutable evidence or concrete facts are not necessary.” The Intercept’s report is based on a U.S. intelligence source, prompting the government to acknowledge Tuesday there’s at least a second active leaker after Edward Snowden.
