It just shows how your innate biases colour your perception of events. Does anyone remember the Grauniad advert showing the black youth running at a man holding a briefcase, viewed from different angles? Some showed it looking like an assault or mugging, the final view showed he was saving his life.
The best bit I found was that the "Middle Eastern" men looked at each other!
When you're in foreign lands, do you make eye contact with other westerners? Does that make you a terror suspect in their eyes?
Besides, if they had been terrorists, we wouldn't have heard this story at all
