As a white guy who was caught accidentally carrying a large knife once through security, at the bottom of a carry-on backpack I'd had since high school, I don't think it's in any way essential to use racial or ethnic markers to figure out whether someone is taking something dangerous onto a plane. I didn't even know I was trying to bring a knife onto a plane at a regional airport. There's no reason to think that Sikhs are explicitly going out of their way to hide something.
