I disagree. No conspiracy is needed when institutional stupidity works.
I first became suspicious there was a terrorist attack in the works about a month before the Boston bombing.
Didn’t know any of the details, just the first hint there was a terrorist attack in the works.
Got a second hint about 2-3 weeks before the attack.
Got a 3rd hint from Eric Holder about a week before the attack.
If I can do it, they can do it.
They did it under Bush, they can do it now.
