While the government initially claimed that mass surveillance on Americans prevented more than 50 terror attacks, the NSA’s deputy director John Inglis walked that position back all the way to saying that – at the most – one (1) plot might have been disrupted by the bulk phone records collection alone.

The government greatly exaggerated an alleged recent terror plot for political purposes (and promoted the fearmongering of serial liars). The argument that recent terror warnings show that NSA spying is necessary is so weak that American counter-terrorism experts have slammed it as "crazy pants"
