"Collect It All" Doesn't work

In the wake of this month's terror attacks in Paris, the debate about mass surveillance for counter-terrorism purposes has resurged. While the USA Freedom Act, which would rein in the government's access to phone records of millions of Americans, is about to take effect, some lawmakers are pushing to delay anything that would remove tools from the arsenal of the intelligence community. But as the Brennan Center for Justice's Elizabeth Goitein tells Brooke, there's no evidence that bulk collection of American citizens' phone data has done anything to prevent terror attacks in the 14 years since 9/11. Intelligence officials are drowning in data, says Goitein, and what's needed is a shift away from the mentality of "collect it all."
