1. The muslim, making threats.
2. I'm not flying with any Captain that allows a passenger to make a go or no go decision. That is his ship and if he can't make that call I won't go with him.
I don’t think the captain was asking her to make the decision. I think he was testing the strength of her “hunch” or suspicion. If you’re not willing to miss your connection or get to your destination a little late, you must not feel so threatened. Apparently no one else concurred with her assessment of the situation or had a concern with this fellow passenger.
Sounds like she is trying to get some attention from the media.
