Watched it and don't think he was lying.

In real life when "bad" things happen people act differently than they do in the movies/TV.

People look around them and pay attention to how others are behaving.

They don't know what is really happening.

The whole thing is hard to believe. (for the people there)

For instance--real gunfire sounds nothing like it does on TV/movies--in real life it is like fireworks--pop. pop,pop....not BANG!!

Have you ever been in an airplane when heavy turbulance hits? The plane starts to shake--it is really scary, and images of "movie plane crashes" come to mind--yet everyone remains calm--no screaming.

In the maternity ward in the hospital--there is no screaming--it is very quiet--mothers in real life don't scream out. Been there twice this is my experience.

When you are in a car accident, or hit unexpectedly the pain is not there (at first), shock takes over and you are bewildered.

So, no I am not surprised there was no screaming and people did not act like they were in a movie.
