It's a wretched yet predictable ritual after each new terrorist attack: Certain politicians and government officials waste no time exploiting the tragedy for their own ends. The remarks on Monday by John Brennan, the director of the Central Intelligence Agency, took that to a new and disgraceful low ... after coordinated terrorist attacks in Paris killed 129. Mr. Brennan complained about ... the sustained national outrage following the 2013 revelations by Edward Snowden, a former National Security Agency contractor, that the agency was using provisions of the Patriot Act to secretly collect information on millions of Americans' phone records. It is hard to believe anything Mr. Brennan says. Last year, he bluntly denied that the C.I.A. had illegally hacked into the computers of Senate staff members conducting an investigation into the agency's detention and torture programs when, in fact, it did. In 2011 ... he claimed that American drone strikes had not killed any civilians, despite clear evidence that they had. And his boss, James Clapper Jr., the director of national intelligence, has admitted lying to the Senate on the N.S.A.'s bulk collection of data. Even putting this lack of credibility aside, it's not clear what extra powers Mr. Brennan is seeking. Most of the men who carried out the Paris attacks were already on the radar of intelligence officials in France and Belgium, where several of the attackers lived. The problem in this case was not a lack of data. In fact, indiscriminate bulk data sweeps have not been useful.
