Searching for suicide bombers.

Here's a NYT op-ed that makes a compelling argument for a very specific kind of profiling:

[C]ommuters need to be most aware of young men praying to Allah and smelling like flower water. Law enforcement knows this, and so should you. According to a January 2004 handout, the Department of Homeland Security advises United States border authorities to look out for certain "suicide bomber indicators." They include a "shaved head or short haircut. A short haircut or recently shaved beard or moustache may be evident by differences in skin complexion on the head or face. May smell of herbal or flower water (most likely flower water), as they may have sprayed perfume on themselves, their clothing, and weapons to prepare for Paradise." Suspects may have been seen "praying fervently, giving the appearance of whispering to someone. Recent suicide bombers have raised their hands in the air just before the explosion to prevent the destruction of their fingerprints. They have also placed identity cards in their shoes because they want to be praised and recognized as martyrs."

The op-ed writer, Paul Sperry, says that once you're on the train and see someone like this, it will be too late. It's necessary for the police to stop the man from boarding the train.

Currently, the official search procedure is to randomly select one person out of five -- the old as well as the young, females as much as males. Actually, I find it hard to believe that they aren't also noticing men with recently shaved beards and smelling of flower water. But isn't it better not to mention they are?
