I am always amazed at the millions of people that travel by plane each day all over the world. Among those millions traveling are women that wear scarves and men that have beards. They are able to board a plane and arrive to their destination without questions being asked.

If a person did not report a suspicious conversation and a disaster occurred, how horrible would that be? Almost 4000 lives were lost on 9-11. That is a fact that will never be forgotten.

The pilot must feel safe in order to get the plane and the passengers on board to their destination safely. Period.

Heed the warnings. Like you posted, Scarlet, announcements are made and warnings are posted everywhere in the airport. Listen and read. Don't bring attention to yourself by having a dialogue with others that can be misconstrued.
