"I think the real question is, why did the French allow the passenger to get on the plane?"
Answer.
To get rid of them. As in. Move along there.

Here is a thought. Perhaps ew know the French are letting them on the plane.

Perhaps the French have let them on the plane, then notify the US so that we can catch the bad guys.

Although I m inclined to think that France is our enemy, this is a possibility.
