If the ‘raghead’ ahead of you was actually wearing a turban, there’s a good chance he was a Sikh, not a Muslim, and would have been the first to jump into the fray in defense of the airplane and passengers if a Muslim started anything. (The Sikh custom of carrying a dagger ‘to fight injustice’ was instituted in response to the injustices of Muslim persecution of Sikhs.)
Did his turban cover his ears? If so, he was a Sikh.
