WELL... yesterday on an AA flight from JFK to LAX, my friend fell asleep while the plane was delayed on the runway with passengers on board. She awoke to two men in FBI jackets shaking her and asking her if she had anything in the overhead compartment. She said no and they hauled off three men that were sitting in front of her. She said all three men looked to be in their early 20s and to be Middle Eastern. They then had to deplane while they did a security sweep of the aircraft and were then allowed to leave.
When she aked why the men were taken off the plane she was told that "their IDs didn't check out".
