Hey! I belong to the same religion! We call ourselves the 1911A1/24/7 society. Don't mess that, officer, it's a religious artifact! I'm being oppressed by the man!
Seriously, while I respect the Sikhs right to wear a dagger if that is part of their faith, the same authorities would not let other students run around campus wearing a 6-inch blade, they would be arrested or expelled.
How about a ceremonial Kbar? I can carry that too right? I am pretty sure that is in the 1911A1/24/7 Society code some where.
