Same here.
Just a guess, but I would say he knew why the date of the bombing was changed from the original July 4th date and why they had been instructed to “spontaneously” plan an attack on New York after the Boston bombing.
Nothing quite like using another terrorist attack to make it appear as if a lie from another terrorist attack just might be true.
I bet you he was doubled and saw a chance to attack his case officer. Or his case officer saw a chance to clean up his case file.
