The Trouble with Airport Profiling

Why do otherwise rational people think it's a good idea to profile people at airports? Recently, neuroscientist and best-selling author Sam Harris related a story of an elderly couple being given the twice-over by the TSA, pointed out how these two were obviously not a threat, and recommended that the TSA focus on the actual threat: "Muslims, or anyone who looks like he or she could conceivably be Muslim."

This is a bad idea. It doesn’t make us any safer -- and it actually puts us all at risk.
