Well, people with turbans, Sikhs, always carry two symbols of their religious faith, a Kirpan, which is a dagger, and a chakkar, a steel bracelet which is derived from an edged throwing ring. There’s also the khandar, a double-edged sword. Sikhs are, after all, a martial people, reflected in the symbol of their religion, the Khanda.
They also never cut their hair, which might also cause issue with border controls and their stupid scanners.
Sikhs are not people to mess with, which is why we Brits were only too glad to have them fighting on our side during WW2
