TSA
You know, it would be just like the TSA to get bent out of shape by a turban. Where I live in California, I don't think I have ever seen a turban on a Muslim. Only on Sikhs, very common here, who are definitely NOT Muslim, but have had to put up with some crap from people who don't know that.
All I'm looking for is common sense in the driver's seat instead of politics and PR. Given the patterns, odds are enormously in favor of a Muslim being the perpetrator in a potential terrorist attack. That doesn't mean a "Muslims Only" line, but it might mean wasting fewer expensive resources on nuns, little old ladies from Kansas, and five-year-old kids.
Richard Reid's biography can be found here. I don't think he proves your point very well.
