I was watching TV with my 8 year old Niece this afternoon, and they were showing footage of the towers collapsing. There was a particular scene where the second building had just collapsed, and it got real quiet and dark. Afterwards, there were people wandering about the streets like ghosts, and there was a shot of these 3 firefighters walking down the street, AWAY from the carnage. My 8 Year old Niece looks puzzled at what she is seeing and says to me "Uncle, why are the Fireman walking away from the fallen building like that? Shouldn't they be going in the other direction so they can help rescue injured people?". She actually made a very interesting observation. There were lots of fireman who, after the buildings collapsed, were walking away from the destruction, slowly, almost as if they mentally shut down.
