Check out the mug shot of the world’s dumbest terrorist.

After his arrest, Faisal Shahzad was questioned in a Brooklyn hotel, where he spun fantasies about attacking Boston, Washington and landmarks across Manhattan and asked investigators why his car bomb in Times Square failed to go off.

The answer is this mutt was unable to build a working bomb almost any idiot could make.

And that was after he went all the way to Pakistan for bomb-making classes.

The problem is there must have been more than one student in the class and not all of them could have been dunces.
