No news here

It's nothing new. DTW was an early pilot city for TSA's Behavior Detection Officers... along with BOS. This technique has been advocated by security experts for years because of its combination of relative effectiveness and being within U.S. discrimination laws (what you say in response to their questions is irrelevent -- it's how you respond that they are observing).

As part of TSA’s risk-based, intelligence-driven security approach, TSA is piloting an expanded behavior detection program in which specialized behavioral analysis techniques are used to determine if a traveler should be referred for additional screening at the checkpoint. The vast majority of passengers at the pilot checkpoints will experience a “casual greeting” conversation with a Behavior Detection Officer (BDO) as they go through identity verification. This additional interaction is used by security agencies worldwide and enables officers to better verify or dispel suspicious behavior and anomalies.
