The people who boarded flight-93 as well as the other three flights on 9/11 weren't scared either. Neither were the ones who boarder the shoe-bomber's plane or the latest undie-bomber's plane. The folks at Ft Hood weren't scared, especially the pregnant woman. Its not a matter of being scared, its a matter of being stupid or naive'. When there are people committed to killing you and your families its stupid not to take precautions, especially profiling.
