Somehow, I've manage to avoid learning that Sikhs are required by their religion to carry a dagger:
The kirpan, one of five items baptized Sikhs are required to wear, is meant as a reminder of the duty to uphold justice. The others are reminders of other things: the kesh, or Sikhs' uncut hair, to live as God created you; kanga, a wooden comb, to remain neat; kara, a bracelet, to do good deeds; and kachera, or large underwear, to remain chaste and faithful sexually.
The story is about Homeland Security maybe being a little less asshole-ish to one particular group of brown folk, but I'm more excited about a whole group of people being required to pack a blade!
