alt Hacker NewsI don't know why this is being downvoted. The federal government has never really prevented a terrorist attack that they themselves have not recruited. It is entrapment, and it is legal in most cases. I know it sounds like a conspiracy theory, but even mainstream media has covered this: https://www.theguardian.com/world/2011/nov/16/fbi-entrapment...
It is perfectly reasonable to suspect similar claims of catching "spies".
Your article doesn't support your claim that the 'federal government has never really prevented a terrorist attack'. And a lot of that was highly motivated reporting itself by people like Glenn Greenwald who was basically denying that things like ISIS were real threats at all in 2014 and then went full victim blaming for things like Charlie Hebdo the year after (it was harder after the Bataclan).
Will you next claim that the police have never really prevented a murder?
