They weren't a "sleeper cell." They came to America and immediately started training for the attack and once they finished the training they went and carried it out. They were also under government surveillance. A sleeper cell by definition is supposed to stay in a prolonged state of dormancy to avoid detection, hence the operative word being SLEEPER. It sleeps!
But good luck with convincing the retards on this board that those guys ever even existed.
