Legion d'Honneur for Americans suppressing Train Terrorists.

TV shows the three Americans and one Brit  accepting France's highest honor, the Legion d'Honneur from the president of France.  The Americans are wearing knit polo shirts and khaki slacks.  To my way of  thinking, they should have been wearing coat and tie for such a ceremony.  We were required to wear coat and tie merely to go to dinner at my old prep school, let alone receive the Legion d'Honneur.  Oh well, they are heroes, and they make me proud to be an American.
